Description
Extending the gear ratio is useful if the engine performance has been increased by successful tuning measures. With the extended gear ratio you can convert your extra power into more speed.
In addition, the cylinders and the rest of the engine are spared, because they don’t have to be revved up as much.
In series engines a longer gear ratio is usually not useful, because in most cases the power is not sufficient to convert the extra gear ratio into top speed.
We deliver the top performances secondary gears ready pressed.
What you have to pay attention to is that you have installed the right gear cover. Original Minarelli engines as used in MBK, Yamaha, Aprilia, Malaguti have a bearing guide. With the derivates of the engine the shaft is simply guided in aluminium. A suboptimal solution, which is not compatible with tuning measures.
