Yamaha has a rich heritage of building supersport motorcycles designed to deliver the pinnacle of performance on and off the track. The YZF-R1 is forged from the technology and development gained from countless racetrack challenges, from MotoGP to the Canadian Superbike Championship. From crossplane crankshaft engines to revolutionary electronics such as the six-axis Inertial Measurement Unit (IMU), Yamaha’s historical achievements have become the future of R World.

Developed without compromise and constructed with the most sophisticated engine and chassis technology, the R1 is the ultimate Yamaha supersport.

KEY DIFFERENCES BETWEEN R1M & R1

- Premium Öhlins Electronic Racing Suspension (ERS)

ENGINE

Ultra-lightweight, compact, 998 cc, DOHC, 16-valve (4-valves / cyl.), liquid-cooled, inline four-cylinder engine with crossplane-style crankshaft.

Redesigned in 2020: cylinder head, fuel injectors, finger-follower rocker arms and camshaft profiles

- 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 race-winning M1 MotoGP racer. The R1 crossplane crankshaft locates the centre two rods at a 90-degree plane from the outer cylinders. 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. 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 / throttle control allows.

- The key engineering goal for the R1 series is significant horsepower with excellent controllability, making the bike easier and more enjoyable to ride. The R1 is a rider’s machine.

ELECTRONIC RIDER AIDS (YRC)

Many of the following rider assist aids are derived from Yamaha’s MotoGP race efforts and help make the R1 more controllable and enjoyable to ride. We call them Yamaha Ride Controls (YRC).

At the heart of the “Yamaha Ride Control” electronic rider assist aids are the Inertial Measurement Unit (IMU) and Electronic Control Unit (ECU).The IMU features six axis of measurement using a gyro sensor to detect rotational motion in the pitch, roll and yaw directions. A G-sensor detects acceleration / velocity in the forward/back, up/down and left/right directions. The vehicle position information obtained from the two sensors including bank angle, pitch rate and sideways slide acceleration is sent to the ECU, which in turn controls the five YRC systems (not including the quickshift system). These variables are calculated 125 times per second.

PWR: Power Delivery Mode is Yamaha’s variable throttle control, which controls the throttle valve opening speed, enabling the rider to adjust performance characteristics of the engine based on riding preferences or conditions. There are four power settings available from an enhanced race setting to a slippery condition mode with softer power characteristics.

TCS: Traction Control System with lean angle sensor. System uses front and rear wheel sensors to detect slip and then adjusts / regulates power via the ECU / IMU to control rear wheel spin. In addition to detecting difference in speed between the front and rear wheels, the system uses input on the degree of bank / lean angle to adjust the degree of TCS intervention to an optimum level in relation to riding conditions in real-time. As the banking angle increases, the amount of TCS intervention also increases. When the TCS is disabled, SCS, LIF and LCS systems will automatically be shut down as well. There are 9 settings plus off.

SCS: Slide Control System controls engine power when side slip is detected. Power output is adjusted to an optimum level to control side slide. There are 3 settings plus off.

LIF: Lift Control System (a.k.a. anti-wheelie control) reduces time loss due to wheelies during closed course competition. System reduces front end lift during starts and hard acceleration. When the IMU and other sensors detect lift, engine output is adjusted to the optimum level to maintain strong acceleration without lift. There are 3 settings plus off.

Revised Launch Control System ensures fast, strong, controllable starts in closed-course competition situations. When the LCS is activated, it keeps the engine limited to a specific rpm and maintains an optimum level of engine power in conjunction with inputs from the TCS and LIF systems, allowing the rider to concentrate on clutch engagement and the other competitors, reducing stress associated with race starts. There are 2 settings plus off.

QSS: Quick Shift System provides smooth, fast upshifts even at full throttle. When the switch on the shift lever rod detects motion, it adjusts engine output and momentarily cancels out the drive torque to promote faster gear shifts. There are 2 settings plus off.
