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.
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.
