Honda CB72 & Honda CB77 5 Speed Road Version Gearbox

<< back to products

The Nova Honda CB72 & CB77 gearbox is a direct replacement for the standard four speed transmission. The gear ratios have been chosen to reflect the sporting aspirations of the CB72/CB77 but still allowing for practical use around town. The additional gear requires the removal of the kickstart mechanism.

The CB77 & CB72 five speed gearbox is supplied with both shafts assembled, requiring only shaft support bearings. The five speed selector drum is supplied with three selector forks and a completely revised selector mechanism.
