ALL NEW FOR 2009
*In the supersport liter class, there’s always lots of talk about power. You expect that. What you wouldn’t have expected – until now – is a radically superior way to deliver that power. Introducing the 2009 YZF-R1, the first ever production motorcycle with a crossplane crankshaft. Crossplane technology, first pioneered in MotoGP racing with the M1, puts each connecting rod 90° from the next, with an uneven firing interval of 270°- 180°- 90°- 180°.
*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.
*The R1 features Yamaha D-MODE (or drive mode) with rider-selectable throttle control maps to program YCC-T performance characteristics for riding conditions. The standard map is designed for optimum overall performance. The “A” mode lets the rider enjoy sportier engine response in the low- to mid-speed range, and the “B” mode offers response that is somewhat less sharp response for riding situations that require especially sensitive throttle operation. Switching maps is as easy as pushing a button on the handlebar switch.
*In keeping with this machine’s exceptional cornering ability and crisp handling, the all new aluminum frame has been designed to offer exceptional rigidity balance. The rear frame is now lightweight CF die-cast magnesium, contributing the optimum mass centralization. Suspension includes new SOQI front forks which use one of the tricks developed for our winning MotoGP bikes: independent damping.
*Slipper-type back torque-limiting clutch greatly facilitates braking/downshifting from high speed.
*The new SOQI rear shock both high and low speed compression damping plus an easy-to-use screw adjustment for preload. This unit also adopts a pillow-ball-type joint for exceptional shock absorption, road hold feeling, and damper response. To achieve maximum performance, a new bottom linkage is used to work with the rest of the chassis refinements for brilliant, crisp handling characteristics.
Factory racers get machines tailored to their preferences. Welcome to the club. R1 has adjustable footrests, with a 15mm height and 3mm front-to-rear adjustment.
