02-05 Honda CRF450R Close Ratio 5 Speed Gearbox
This gearset is a direct replacement to the Honda CRF 450 5 speed motocross gearbox with the added advantage of undercut engagement dogs and road racing ratios.
The Nova close ratio gearbox gives a performance gain of up to 1.5 seconds a lap depending on the length of the circuit. The gear ratios are optimized for road racing to keep the engine working between its peak torque and peak power. The ratios of the standard box are designed to give tractability off-road, and as such cause the engine revs to drop below peak torque meaning drive from the engine is not optimized. Over the length of a 3.9km circuit, lap time improved by 1.5 seconds.
This kit includes only the loose gears.
Superfinished in house as standard.
