2019 Yamaha YZF-R1

Packed with MotoGP technology, crossplane concept engine, advanced Rider Active electronics and so much more.

Features may include:

• Engine

The 998cc inline 4-cylinder, crossplane crankshaft engine features titanium fracture-split connecting rods, which are an industry first for a production motorcycle. The titanium alloy used to manufacture the connecting rods is around 60% lighter than steel, and this reduction in weight gives the R1 engine a responsive and potent character at high rpm. This stunning engine delivers extremely high horsepower and a strong pulse of linear torque.

A 6-speed transmission features close-ratio gearing to best match the high-revving engine. The transmission also stacks the input/output shafts to centralize mass and to keep the overall engine size shorter front-to-back, which optimizes engine placement in the frame for outstanding weight balance.

• Electronics

Yamahas Inertial Measurement Unit (IMU) uses six axes of measurement: a gyro sensor that measures pitch, roll, and yaw, and an accelerometer that measures acceleration in the fore-aft, up-down, and right-left directions all at a rate of 125 calculations per second. The IMU communicates with the ECU, which activates the technologies in Yamaha Ride Control (YRC): Power Mode, Traction Control System, Slide Control System, Launch Control System, Lift Control System and Quick Shift System with rev-matching. All these systems are adjustable and can be saved within four presets in the YRC system.

The ride-by-wire Yamaha Chip Controlled Throttle (YCC-T) system senses the slightest throttle input by the rider and instantaneously calculates the ideal throttle valve opening, and then actuates the throttle valves to actively control intake volume. The R1 also features YCC-I (Yamaha Chip Controlled Intake), a variable intake system that broadens the spread of power in across the entire rpm range.

• Chassis/Suspension

The slim aluminum Deltabox frame and magnesium subframe contribute to a light weight and compact chassis design, with overall geometry refined on racetracks around the world. The rigid motor mounts use the engine as a stressed member of the frame for optimal rigidity balance and great cornering performance on the race track.

The R1 features an advanced inverted KYB front fork with 43mm inner tubes and a 4.7 inch stroke with full adjustability, for incredible front-end feel on the track. All adjustments are also made on the top of the fork legs, for simplified tuning.
