5 Speed gearbox with reverse gear
The gearbox gets an additional device, the reverse may only be inserted while idling.
No other gear can be shifted now.
A safety device prevents any incorrect circuits and all 5 forward gears are maintained.
The conversion is possible for models before 1980 and after, also for models with and without kickstarter.
The optional installation of a short 1st gear is possible, make sense especially for sidecar bikes.
All 6 bearings, gasket and seals are new!
The installation of a reversing light through the additional switch is also possible
Currently a gearbox is available ( in exchange).
