Key Features

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.

Engine Features

To maximize rider comfort as well as power output, this newly designed engine adopts a coupling-type balancer that rotates in the opposite direction as the crankshaft. The exhaust system is completely new. It’s meticulously designed to enhance engine output while, thanks to its threeway catalyst technology, also reducing exhaust emissions. The silencer is a single expansion type, and, the sound coming through from the unique crossplane-crankshaft-equipped engine is unlike any other in-line four cylinder production supersport.

Chassis Features

The frame is completely revamped, with 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. No one-technique-fits-all-needs design, it is a sophisticated combination of CF die-cast, stamping, and gravity casting… the exact technology needed for each portion of this advanced frame. The press-formed fuel tank has a shape developed using 3-D simulation analysis technology. The elongated shape of the tank allows it to fit neatly within the frame in a way that promotes concentration of mass.
