<< back to products

Full six speed close ratio gear set comprising both input and output shafts and all gears, selector drum with indexing block and using standard selector forks.  Supplied fully assembled ready for installation.

All engagement dogs are undercut and have three dogs to promote positive and rapid engagement.

Due to the change in diameter of the gears, the kickstart mechanism will not work with this gearbox, therefore roller starters will be required to start up.

 

ENSURE YOU SPECIFY 6 OR 24 CLUTCH SPLINE ON THE INPUT SHAFT WHEN ORDERING

 

NOTE: A small modification is required to the standard selector forks, this is simply to clear the Nova gears whe shifting.  For instructions CLICK HERE.
