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.
Note - for Benelli 125cc before 2000.
Secondary transmission 14/43.
