2009-2012 Yamaha R1 Gearbox

<< back to products

A direct replacement of the standard gears, we supply all loose gears for both shafts.  All gears incorporate 3 undercut engagement dogs for rapid changes and positive retention when engaged.

 

The standard clutch is retained and the gearbox should be assembled using the standard input shaft, output shaft, bearings, bushes, thrust washers, circlips etc.
