Yamaha YZF-R1

YZF-R1 

benefits from MotoGP® technology – a seven-level Traction Control System. The system has been developed so the rider does not feel any unnatural or harsh intervention from the system. In addition, traction control can aid in reducing tire wear due to less wheel spin. Coupled with the three level D-Mode electronic throttle response control, riders have 21 different choices available to tailor the YZF-R1 to their riding preference.

R1 keeps all the technological superiorities developed for its predecessor: YCC-T™ (Yamaha Chip Controlled Throttle) is MotoGP® inspired fly-by-wire technology used to deliver instant throttle response. YCC-I® is Yamaha Chip Controlled Intake which is a variable intake system that broadens the spread of power. The fuel injection system provides optimum air/fuel mixtures for maximum power and smooth throttle response.

In keeping with this machine’s exceptional cornering ability and crisp handling, the aluminum frame has been designed to offer exceptional rigidity balance. The rear frame is lightweight Controlled-Fill die-cast magnesium, contributing the optimum mass centralization. Suspension includes YHSJ (Yamaha Hydraulic Systems Japan) front forks which use one of the tricks developed for our winning MotoGP® bikes: independent damping. The left fork handles compression damping and the right side handles the rebound damping. And the rear shock adopts bottom linkage for optimum suspension characteristics.

Sound on the YZF-R1 is unlike any other inline-four cylinder production supersport. The precise and throaty pulse of the exhaust note will have riders enthused every time the throttle is opened.
