This is a functional model of a motorcycle gearbox loosely based on Yamaha XV535 Virago.
I will be uploading the shifting mechanism and housing shortly.
UPDATE, 5.11.2017:
MainShaft: Added endpoints for mounting, spacers and circlip bores
FourthGearM: Fixed bore to match main shaft
DrivenShaft: Added endpoints for mounting, spacers and circlip bores
