Yamaha R1 Crossplane Motor

The crossplane crank motor also known colloquially as bing bang though this isn t strictly what it is fires its pistons in a unique firing order in order to reduce inertial torque and improve cornering.

Yamaha r1 crossplane motor.

The 2009 r1 was the first production sportbike to use a crossplane crankshaft. Yamaha currently offers three versions of the yzf r1. The power delivery is the same as a 90 v4 with a 180 crank such as the honda vfr800 and very similar to the yamaha v max which has been lauded for its exhaust sound. The base r1 the higher spec r1m and the entry level r1s.

Yamaha yzf r1 sport motorcycle.

This was inspired by yamaha s m1 motogp racing models which continue to use crossplane cranks to this date because of their significant inertial torque advantage at the extreme high rpm operation these engines. The yzf r1 come equipped with the next generation of yamaha s unique 998cc inline four cylinder crossplane crankshaft engine for refined performance.
