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.

Features may include:

• 4-valve cylinder head design

compact pent-roof combustion chambers with 13:1 compression ratio

• Special intake port shape provides maximum filling efficiency.

port shape, valve placement and combustion chamber shape induce a tumbling effect of the inbound fuel - air charge that increases combustion speed, power and torque

• 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.

• Gravity-cast aluminum Deltabox frame

designed to offer an optimized rigidity balance to maximize handling and suspension performance. Frame provides a balance of strength, rigidity and tuned flex

• Polished, lightweight aluminum upward truss-type swingarm

provides great torsional rigidity for excellent rear wheel traction and control
