YZF-R125 specifications
| 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�. This all but eliminates undesirable inertial crankshaft torque, which allows the engine�s compression torque to build smoothly and provide a very linear power delivery out of the corners. It�s a feeling that�s simply unmatched, like having two engines in one: the low-rpm torquey feel of a twin with the raw, high-rpm power of an inline 4. In fact, the new YZF-R1 is not a continuation of existing supersport development; it is breakthrough technology that represents a paradigm shift in both technology and performance.
- This next-generation 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.
- 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. The left fork handles compression damping and the right side handles the rebound damping. And the rear shock adopts new bottom linkage for optimum suspension characteristics.
- All new bodywork does more than add break-away-from-the- crowd styling. Completely new, the new model has a more serious, less busy look. The side fairing is smoother for a sleeker appearance. And, instead of the usual four bulb headlight design, the �09 model now has only two projector-type bulbs mounted closer to the nose of the bike. This positions ram air ducts closer in for a more compact, smooth look. In addition, the rounded lenses are new and unique to the supersport industry.
