Malossi Secondary Transmission 16/42 Gilera Runner 125-200cc 4-stroke

A longer transmission will get the power where your need it and increase your top speed, always under the condition that your engine is powerful enough to begin with. This means you should definitely use this transmission with tuning cylinders only, as original cylinders are simply not powerful enough.

Secondary transmission 16/42.
