2004-2007 Kawasaki ZX10R Standard Ratio Gearbox Alternate 6th Gear – Improved Dog Design

We also offer two alternate ratios for 6th gear, designed to work with the Nova gearbox listed above only. These were designed for endurance racing to keep the engine RPM down in top gear. This helps to reduce engine failure due to prolonged use of top gear over a long race distance.

One pair is classed as wide ratio and the other acts as an overdrive.

A 6th input gear and 6th output gear is supplied per kit.

NOTE: These are only compatible with the full Nova gearset listed above.
