2010 Yamaha YZF-R1

2010 Yamaha YZF-R1

1 . The YZF-R1 garnered the prestigious award as the 2009 Motorcycle of the Year from Motorcyclist Magazine. The YZF-R1 was chosen for its MotoGP®-inspired engine and chassis technology, and for its luxurious fit and finish.

2 . Back for 2010, the YZF-R1 is the only production motorcycle with a crossplane crankshaft. Crossplane technology, first pioneered in MotoGP® racing with the M1, puts each piston 90° from the next, with an uneven firing interval of 270°- 180°- 90°- 180°. This uneven order does an amazing thing… it actually lets power build more smoothly. That means smooth roll-on delivery out of the corners, with outstanding tractability, followed by very strong high rpm power. 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 four. This breakthrough technology on the YZF-R1 represents a paradigm shift in both technology and performance.

3 . This 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.

4 . 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 for riding situations that require especially sensitive throttle operation. Switching maps is as easy as pushing a button on the handlebar switch.

Engine:

Crossplane crankshaft technology proven in victory after victory on MotoGP® machines provides a high-tech uneven firing interval. Unlike typical inline-four engine design, where the two outer and two inner pistons move together in pairs with 180° intervals, the crossplane crankshaft has each connecting rod 90° with a unique firing order of 270° – 180° – 90° – 180°. This overcomes the inherent fluctuations in inertial torque during each engine revolution, and the accompanying peaky torque characteristics. Instead, combustion torque continues to build, giving the rider more linear throttle response with awesome power and traction out of the corners.

To maximize rider comfort as well as power output, the engine adopts a coupling-type balancer that rotates in the opposite direction as the crankshaft.

The frame has a combination of uncompromising rigidity where needed along with carefully achieved flex for the precise rigidity balance this bike needs to give the rider the full benefit of its handling and engine characteristics. It is a sophisticated combination of Controlled-Fill die-cast, stamping, and gravity casting … the exact technology needed for each portion of this advanced frame.

SOQI front forks take a page from the championship-winning design of our MotoGP® weapon, the M1. Since both forks always move together, compression damping duties can be confined to the left fork, while rebound damping is precisely handled by the right fork, reducing oil cavitation.

The instrumentation includes everything a rider wants to know, including gear position.
