YAMAHA WGP 50TH ANNIVERSARY MODELS

Fifty years after Yamaha sent its first ever GP riders to compete in the World Championships, our newest factory rider Ben Spies helped to commemorate the occasion with his maiden MotoGP win at Assen in June 2011. Riding a YZR-M1 in Yamaha's specially-designed red and white WGP 50th Anniversary livery, Spies was continuing the strong tradition of winning that has enabled Yamaha to become one of the industry's most innovative and creative manufacturers.

Ever since it made its first motorcycle, Yamaha has believed that racing improves the breed. From winning our first ever Grand Prix points at the Isle of Man TT in June 1961 through to this year's MotoGP victories by Jorge Lorenzo and Ben Spies, every single success on the track allows our engineers and designers to develop and refine tomorrow's cutting-edge street-bikes.

Over the past fifty years Yamaha's racing programme has led to the development of some of the most innovative engine and chassis technologies -as well as the creation of the most ground-breaking race-developed models like the YZF-R1, whose crossplane crankshaft is a direct spin-off from the factory YZR-M1 racer.

To celebrate half a century of success in Grand Prix racing, Yamaha will produce a limited quantity of exclusive 'WGP 50th Anniversary' motorcycles and scooters. Based on the classic colour schemes debuted on the YZR-M1 by Jorge Lorenzo and Ben Spies in 2011, this very special timeless livery is inspired by the famous red and white 'speedblock' design featured on Yamaha's pioneering Grand Prix racing machines.

This desirable and exclusive WGP 50th Anniversary colour scheme will be available on limited quantities of YZF-R1, YZF-R6, YZF-R125, FZ8, Aerox and TZR50 for the 2012 model year. Owners of these exclusive new WGP 50th Anniversary models will receive a special certificate of authentication, and will also receive Yamaha's 'Insider' magazine which contains the latest news, interviews and new model information.

In addition to the ECU changes and new traction control system, which combine to achieve a new level of drivability, the R1 features a more aggressive fairing "face" with new eye catching LED illumination lights. Other new styling highlights include the muffler covers and muffler end tips plus a MotoGP inspired lightweight top triple clamp.

The 2011 AMA Superbike Championship winning R1 with its cross plane crank and uneven firing order has taken another evolutionary step forward for 2012 with the addition of traction control and revised ECU settings. These changes make it easier for the experienced rider to bring out the full performance of the new 2012 Yamaha YZF-R1 50th Anniversary Edition while enjoying the unique character and sound of the revolutionary cross plane engine.

With back-to-back American Superbike Championships, and more MotoGP-inspired than ever, the R1 is the world’s most advanced Open-class production motorcycle.

The 2012 Yamaha YZF-R1 50th Anniversary Edition is unlinke anything before. Benefitting from even more MotoGP technology for 2012 with new sevel-level traction control and the World GP 50th Anniversary livery option. The World GP livery includes a 50th Anniversary emblem on top of the fuel tank and a special numbered plate showing the production number of only 2000 units that will be produced worldwide. From the track to the street, it truly is "the 1."

2012 Yamaha YZF-R1 50th Anniversary Edition Features and Benefits

ENGINE

Ultra-lightweight, compact, 998cc, DOHC, 16-valve, liquid-cooled, 40 degree inclined, in-line four-cylinder engine with "crossplane" style crankshaft.

The key components of this cutting edge engine design are the "crossplane" crankshaft and an uneven firing order. Both of these features are used on Yamaha's championship winning M1 MotoGP racer. Please note … this is not a "big bang" engine. The R1 departs from the norm for in-line 4 cylinder engines and the 180 degree alignment of the crank pins (where the connecting rods attach to the crankshaft), and locates the center two rods at a 90 degree plane from the outer cylinders. This means instead of the crank pins aligned on the same plane (a straight line drawn through the center of the crankshaft), they align on 2 planes in the form of a cross ... or "crossplane". Working in conjunction with the crossplane crank is an uneven firing order. A traditional in-line 4 cylinder's firing order is normally 1,2,4,3 with a 180 degree interval. This R1 engine fires 1,3,2,4 cylinders and the firing intervals are uneven at 270 / 180/ 90 /180 degrees. What all this means to the rider is the most linear torque possible and amazing throttle control. This engine design allows a whole new level of rider - machine communication. One of the most important benefits is the outstanding cornering performance that increased engine control allows.

The engineering goal for the R1 is controllability … not just an increase in horsepower. If that was the case, we could have simply increased the power output of the existing engine design resulting in a peaky, hard to use power band.

The 4-valve cylinder head design features a compact combustion chamber that utilizes lightweight, trick, titanium valves on the intake side. The 4-valve design maximizes breathing efficiency and overall engine performance.

The titanium intake valves are 31mm in diameter while the steel exhaust valves are 25mm in diameter. Lightweight yet super strong VX alloy valve springs control valve movement.

Steep valve angles, 11.5 degrees on the intake side and 12.5 degrees on the exhaust produce a compact combustion chamber.

The lightweight titanium intake valves reduce the reciprocating weight of the intake valves allowing for higher rpms without the concern of valve float. The use of lightweight "Ti" valves has allowed the engineers at Yamaha to use a 4-valve format. In the past, the use of 5 smaller valves allowed a higher rpm limit since each of the "smaller" valves was relatively light. The use of light weight titanium now means the engineers no longer have to use the 5-valve design to achieve the same high rpms.

Combustion chambers have been optimized for maximum engine performance. The compression ratio is 12.7:1.

Compact automatic cam chain tensioner reduces both maintenance and mechanical engine noise.

Short skirt, forged aluminium pistons offer light weight, fast throttle response and great reliability.

Crossplane crankshaft features 36mm journals for increased strength, while the inertial moment of the crank has been increased by 20% versus the last generation R1.

Connecting rods are carburized and use a nut less design. The lower end "cap" of the rod is made from the same piece of material as the upper portion and is cracked away in a process known as "fracture splitting". This process aids true big end roundness and greater precision in con rod dimensions.

Ceramic composite cylinder "bores" are a "liner less" design with the ceramic coating applied directly to the aluminium block to ensure uniform heat dissipation for consistent power delivery, reduced oil consumption, reduced friction and reduced weight.

Closed deck cylinder design allows the cylinders to be spaced more closely together, allowing a narrower engine.

The cylinder block is a stand-alone piece (not integrated into the upper crank case). The benefit is reduced weight and a less tall engine which lowers the centre of gravity.

A "coupling force balancer" is used to quell engine vibration for excellent rider comfort.

Compact ACM (alternator) is mounted directly to the crankshaft. The compact ACM uses rare earth magnets which produce more power for a given size than conventional magnets, therefore reducing size and weight.

Revised Mikuni fuel injection system features twin injectors (one set of primary & one set of secondary injectors). This type of twin injector system is also used on our M1 MotoGP race bike and the R6. One set of injectors (primary) are located in the 45mm throttle bodies while the secondary injectors are located in the air box very near the computer controlled intake funnels. The revised primary injectors utilize 4 spray holes to maximize the fuel atomization process. The secondary injectors, located inside the air box, begin to function at mid rpms onwards to supply more fuel as required.

The F.I. system features separate dual track TPS (throttle position sensor) and APS (accelerator position sensor) sensors

An oxygen sensor is fitted into the exhaust collector making this a "closed loop" type FI system, which feeds back info to the ECU so adjustments can be constantly made to the fuel-air mixture for improved performance and reduced emissions.

The benefits of fuel injection include excellent throttle response, great fuel economy, reduced emissions, stable idling and no choke to fuss with during start up.

The fuel injection's lightweight Electronic Control Unit (ECU) utilizes a powerful 32-bit processor for fast control of the injection process. The compact design also reduces weight.

YCC-I or Yamaha's Chip Controlled Intake means the intake funnels / stacks vary in length (2 positions) depending on engine rpm. An electronic servo motor varies the funnel length from the tall position at low to mid rpms to the shorter setting for improved high rpm power. The transition rpm between the 2 lengths is approx. 9,400 rpms. The revolutionary YCC-I provides the best of both worlds …solid low rpm torque and power combined with an amazing high rpm rush. It takes only 0.3 of a second for the funnels to move from the tall to the short position.

Yamaha's exclusive YCC-I electric-control servo motor-driven variable intake funnel system is a world's 1st on a production motorcycle and works in conjunction with Yamaha's fly-by-wire technology and FI Systems.

Yamaha Chip Control Throttle (YCC-T) electronically controls the throttle valves for outstanding response and improved controllability at all rpms. The YCC-T is used to provide even more control of the intake air volume for smoother torque character. Similar to the R6 design, the YCC-T features 3 - ECU's inside the main ECU to control ignition, fuel injection and the YCC-T. This special ECU is capable of responding to changes at a speed of 1000th of a second.

The rider can "mechanically close" the throttles by simply closing the throttle twist grip.

All new 6 mode traction control system features an off mode as well. This MotoGP derived system limits or eliminates rear wheel slippage or slide based on the chosen mode. This system uses front and rear wheel sensors to detect slip and then adjusts / regulates via the ECU the throttle opening (YCC-T), fuel injection and ignition timing to control slip. The system is activated using a switch on the LHS switch gear. Each mode offers a different level of slip control.

Long life Iridium twin electrode spark plugs are used.

Compact close-ratio 6-speed transmission features optimized gear ratios for maximum performance. The "stacked" 3-axis gearbox / clutch design stacks input/output shafts to create a low center of gravity and keeps overall engine size shorter front to back. As a result, the stacked design gives the engineers the freedom to place the engine in the "sweet spot" of the frame for optimum weight balance for awesome handling.

The slipper or back limiter clutch assembly reduces rear wheel hop when making hard down shifts when under hard braking. Key benefit is reduced lap times and smoother control when riding aggressively during a race or track day.

A multi plate clutch is used, utilizing coil springs and paper based fibre plates.

"Ram Air" system "force feeds" outside air via dual ducts located beside the projector headlights into the intake system. As speed increases the air velocity in the system increases and pressurizes the air box. This "force fed" air helps the engine develop maximum power.

Computer optimized large capacity air box maximizes performance. A viscous type, high flow air filter is utilized.

Revised 4 into 2 into 1 into 2 titanium exhaust system maximizes power output, reduces weight and improves aerodynamics. The dual under seat mufflers provide an aggressive sound. This system contains a 3-way honeycomb catalyzer and an oxygen sensor. The catalytic converter reduces harmful CO and HC exhaust emissions while the oxygen sensor provides feedback to the ECU to maintain optimum fuel/air mixture at all times.

Dual shorty, large diameter triangle shaped mufflers are a "single expansion" type that create a throaty exhaust note and help emphasize engine character. New muffler end caps improve styling. The exhaust note is much different than on previous R1 models due to the crossplane crank and uneven firing order … it sounds very similar to Yamaha's M1 MotoGP race bike.

Compact, high-efficiency curved radiator features dual ring-type fans for maximum cooling efficiency. This curved rad and twin fan design produces more airflow than conventional flat designs to maintain optimum engine temperatures for consistent power output.

Large liquid-cooled oil cooler maintains stable lubricant temperatures for extended engine life. Convenient cartridge style spin-on oil filter.

Convenient clutch cover sight glass ensures easy oil level inspection.

High performance direct ignition coils (ignition coil is built into the spark plug cap) reduce weight while iridium spark plugs and high-output magneto deliver increased spark energy.

Yamaha D-Mode variable throttle control enables the rider to adjust the performance characteristics of the engine based on riding preferences or conditions. Standard mode emphasises the very linear throttle and torque feel of the engine. The A mode allows the rider to enjoy sportier engine performance in the low to mid rpms. While the B Mode reduces the power response for riding situations that require softer power characteristics. The switch mechanism is located on the RHS handle bar switch gear.

New ECU settings for improved drivability / controllability. 

CHASSIS / SUSPENSION

Aluminium Deltabox frame has been designed to offer an optimized rigidity balance to maximize handling performance. This frame is very rigid or stiff at the head pipe, engine mounts and swingarm pivot point. In other areas, material has been carefully removed to allow "tuned flex". Finished in black, this frame boasts a compact 1415mm (55.7") wheelbase. The swingarm pivot location has been optimized to minimize the chain tension effect under hard acceleration, providing more stable handling. The engine is a fully stressed chassis member to maximize handling. Stability, a key to great handling, is unsurpassed while the ability to hold a line under hard acceleration is excellent. This frame features a mix of gravity cast (head stock & front engine mounts & swingarm pivot area), CF (controlled filling) die cast (outer tank rails) and aluminium panels (inner tank rails). Each of these aluminium parts has different flex characteristics in order to provide the rigidity balance the engineers desired.

Detachable magnesium CF die cast rear subframe reduces weight. The detachable design allows rear shock access and is less costly to repair if accidentally damaged.

Extra-long, lightweight aluminium "truss-type" swingarm provides great torsional rigidity for class leading handling, agility and manoeuvrability. This lightweight swingarm is made up of cast aluminium and CF die cast parts. The distance between the swingarm pivot and the rear axle has been optimized (597 mm) for excellent "turn-in" abilities and rear wheel traction.

This Deltabox chassis offers an incredible 56 degree lean angle.

Fully adjustable 43mm inverted fork features independent left and right damping system. The compression damping is adjusted via the left fork leg, while rebound damping is adjusted on the right fork leg. This system simplifies the flow of oil through the fork and minimizes oil cavitation (aeration of the oil) for more stable suspension performance. Adjustments include 5-way spring preload, 25-way rebound and 25-way compression damping. Front wheel travel is 120mm (4.7"). The thickness of the inner fork tubes and the shape of the outer tubes have been optimized. The adjustable design allows the rider to tailor suspension settings to match rider weight and road /track conditions to maximize handling and suspension performance.

New MotoGP M1 inspired, gravity cast aluminum upper triple clamp reduces weight and improves styling.

Revised bottom link Monocross rear suspension utilizes a fully adjustable piggyback-style rear shock. Spring rate has been revised for improved traction feeling while the spring preload adjuster is now an easier to use screw type. Adjustments include 16-way spring preload, 18-way rebound and 20-way slow speed compression damping and 4-way fast speed compression damping. The bottom link design lowers the centre of gravity for excellent handling. This is a rising rate or progressive system. The adjustable design allows the rider to tailor suspension settings to match rider weight and road /track conditions to maximize handling and suspension performance. Rear wheel travel is 120mm (4.7").

Radial mount 6-piston calipers squeeze fully floating 310mm dual front rotors. The result is incredible braking performance with excellent control and lever feedback.

Brembo radial pump master cylinder with 16mm piston is a direct GP race innovation. The lever is adjustable for various hand sizes.

Single piston slide-type Nissin rear caliper squeezes a lightweight 220mm rotor.

Rugged yet lightweight 5-spoke mag wheels front and rear. The wheels utilize hollow "spokes" to reduce unsprung weight for superior handling. Front rim size is a MT3.50 x 17 while the rear is MT6.00 x17.

Premium sport spec radial tires front and rear.

18 litre fuel tank provides excellent knee grip for hard braking and great rider manoeuvrability. The elongated shape helps to centralize mass and reduces the variance in riding feel as the fuel load (weight) changes.

New more aggressive front fairing offers excellent aerodynamics

New LED marker and illumination lighting provides excellent visibility / conspicuousness.

Revised race inspired lightweight instrumentation includes an analog tach plus digital speedo, dual tripmeters, clock, coolant temperature and fuel trip meter. This console also features adjustable back lighting, adjustable shift light and a low fuel warning light. Other key features include a gear position indicator, new traction control indicator, engine mode indicator integrated stop watch, lap timer with split time mode and an air intake temperature display. The lap timer is controlled by the starter switch button for added convenience and ease of use.

LED taillight reduces weight and power consumption while providing a brilliant eye catching light. The lens is white while the LEDs are red. 

ADDITIONAL DETAILS / FEATURES

Adjustable footrests can be raised 15mm upward and 3mm backward if desired.

New design lightweight aluminum rider footrest

Immobilizer ignition system is designed to reduce the possibility of "ride away" theft. This system must recognize the "coded ignition key" in order for the unit to start. If the immobilizer ignition does not recognize the key (or a thief's screwdriver or other type of "jimmy tool") the bike will not start even if the ignition is turned or forced into the on position. If the system does not recognize the coded chip in the ignition key, it will not allow the ignition system, fuel pump or starter motor to function.

Windshield features a "screw less" design for a cleaner, more trick appearance.

Slim design rear tail section.

The seating position offers a very sporty yet comfortable riding position.

Extensive use of hollow bolts and lightweight fasteners help trim overall weight.

Heavy-duty 50 series "O" ring drive chain.

New design 17 tooth drive sprocket reduces chain noise.

2012 Yamaha YZF-R1 50th Anniversary Edition - European Press Release:

2012 YZF-R1 50th Anniversary Edition: ULTIMATE CONTROL

For the 2012 season Yamaha will introduce an uprated YZF-R1 50th Anniversary Edition featuring a range of important MotoGP inspired engine and chassis changes which are designed to elevate the performance and enjoyment of this unique race-proven motorcycle to another level.

Since its launch the latest-generation R1 has set new standards for engine and chassis performance on the road and track, winning the World Superbike Championship at its first attempt in 2009 with Ben Spies. In the 2011 WSB season Yamaha's race-winning factory YZF-R1 50th Anniversary Edition Superbikes have proved to be amongst the fastest and best-handling 1000cc machines, and in many National Superbike and Production race series around the world, the R1 is the machine of choice for front-running racers.

Powered by a 998cc in-line 4-cylinder engine equipped with an innovative crossplane crankshaft, the latest-generation R1 delivers a truly special blend of linear power combined with superior traction and outstanding cornering performance.

Unlike conventional 180º - 180º - 180º - 180º crankshaft designs - which feature con rods and pistons moving up and down in pairs - the R1's crossplane crankshaft features an uneven 270° - 180° - 90° - 180° firing interval which gives each piston and con rod its own individual and separate movement. The combination of an asymmetric firing sequence with the staggered con rod layout makes for a stronger low to mid-range pulse, as well as a more linear torque output for higher traction - and as a bonus the rider can enjoy a truly unique exhaust note!

On the road or track the R1 rewards the rider like no other large-capacity supersport machine, and for even more highly purified excitement the 2012 R1 is equipped with an advanced Traction Control System (TCS) for wider ranging controllability in a variety of conditions.
As every rider knows, a feeling of total confidence in your machine's abilities is one of the most important qualities that any bike can offer, and the new TCS inspires a high level of trust in the new R1's roadholding performance. By monitoring and controlling rear wheel spin, the new TCS creates a special bond between the rider and machine, enabling the owner to exploit the enormous potential of this outstanding motorcycle.

In addition to the new TCS, the latest R1 benefits from an optimised engine control unit for improved corner exits and stronger low to mid-range performance.

A reshaped front cowl enhances the bike's pure race-bred looks, while a newly-designed YZR-M1 style handlebar crown and reshaped footrests make for an even greater feeling of rider-machine unity.

New 6-mode Traction Control System
For the 2012 season the R1 is equipped with an advanced new 6-mode TCS (Traction Control System) which has been developed using feedback gained from the winning Yamaha YZR-M1 MotoGP racer.

The new Yamaha TCS constantly monitors sensors in the front and rear wheels, and when any rear wheel spinning is detected the system alerts the ECU which instantaneously adjusts the degree of throttle opening, fuel injection volume and ignition timing. With six settings plus an 'off' mode, the R1's new TCS can be adjusted to suit differing rider requirements, as well as a wide range of surface and weather conditions - and when used in association with the existing three-mode Variable Map Function, the 2012 R1 offers a total of twenty-one engine set-up options.

The R1's crossplane crankshaft engine has already established an enviable reputation for its high levels of linear torque output, and the addition of the new MotoGP-developed TCS allows the rider to exploit the bike's already high levels of traction to an even greater degree. The benefits of the new TCS are particularly evident on winding roads, where the new system enables and encourages performance-minded riders to bring out the full performance of this remarkable motorcycle.

As well as enjoying their bikes on the public highway, a significant proportion of R1 owners are also exploring the bike's potential in the controlled environment of race circuits, and it is on the track that the TCS gives a real quantifiable advantage. By fine-tuning the system to suit the prevailing conditions, R1 riders can optimise the bike's linear torque characteristics and are able to push harder on the circuit for improved lap times. As well as the undoubted technical advantages it offers, the R1's TCS is also designed to reinforce confidence, allowing the rider to perform at an even higher level on the circuit.

Optimised ECU
In order to achieve a new level of driveability, the 2012 R1 also benefits from the fitment of a new re-mapped ECU. The revised mapping covers the degree of throttle opening for the YCC-T (Yamaha Chip Controlled Throttle), as well as the fuel injection volume and the ignition timing functions. These changes to the ECU improve low to mid-range controllability and out-of-the-hole performance - which, in the real world, equates to stronger acceleration when powering out of slow corners, and better roll-on acceleration when overtaking.

New YZR-M1 style handlebar crown
Another YZR-M1 inspired feature on the 2012 R1 is its new handlebar crown, which is based on the design featured on the Yamaha MotoGP factory race bike. Manufactured from gravity-cast aluminium, this high-specification component underlines the machine's quality feel and appearance.

Also new is the special relief pattern cast into the handlebar crown's back face, which helps deliver an outstanding balance of rigidity to complement the handling characteristics of the compact short-wheelbase chassis.

Newly-designed footrests
For 2012 the footrests have been redesigned, and they now feature a modified tread pattern of cast aluminium protrusions which deliver improved feel and fit. This revised design enables the rider to shift their feet easily and quickly for more efficient body weight transfer when cornering.

New-look low-drag front cowl
A new-look front cowl is introduced for 2012, and as well as giving the R1 a more menacing 'glare', the latest low-frontal-area design offers improved aerodynamics. Compared to the existing model, the section beneath the two 'eyes' of the headlights has been opened, and a sharper line is created above the 'eyes'.

The central nose portion of the cowl sits higher than the existing model, and the surfaces either side of the nose portion have been reshaped. Although relatively subtle, the combined effect of these changes is to refresh the face of the 2012 R1, while at the same time reducing drag.

LED position lamps and linear illumination
The new cowl is equipped with LED position lamps, and a new reflective finish is incorporated in the lower edge of the twin headlight assemblies to give an 'eye line' illumination effect when the position lamps are on. Together with the newly designed cowl, this linear illumination makes for a dramatic look, especially during night time riding.

Hexagonal silencer tail caps
The latest R1 benefits from new hexagonal silencer tail caps for an even sharper and lightweight look, while new protectors fit tightly around the silencers to give a more compact looking tail.
