R WORLD. WE R1.
Packed with MotoGP technology; crossplane concept engine; advanced Rider Active electronics and so much more.
Features may include:
Cutting-Edge Crossplane 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.
Compact Stacked Transmission
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.
Yamaha’s 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.
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.
Fully Adjustable KYB® Fork
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.
