Secondary transmission Minarelli horizontal long crankcase 14/41 Polini

The transmission ratios extend the final ratio of the motorcycle.
If the engine has enough power and can handle a longer transmission ratio, the top speed is increased.
The original cylinder in most cases does not have enough power, it will need to be replaced with a more powerful one.
