Primary transmission Minarelli horizontal long crankcase 13/43 Stage6

To extend the transmission ratio, a longer transmission is needed, which results in an increase in top speed.

The original cylinders do not have enough power for a longer transmission, which is why we recommend combining this transmission with a more powerful cylinder.
Unlike standard transmissions, those developed by Stage6 are already compressed. Remove the stock transmission, install the Stage6 transmission, and you're done.

NOTE!: Count the teeth on the original transmission, as the number of teeth on the intermediate shaft must be the same as in the article. If you are not sure which is the ideal transmission for your setup, please contact us.

Primary 13/43 (1:3.31), original shaft = 13 teeth

NOTE! For lightly tuned engines, we recommend the 13/44 transmission (extends by 15.50%), for highly tuned engines you can use the 14/42 setup (extends by 25.00%).
The 16/40 transmission (extends by 60.00%) can only be used on fully tuned engines! If you are not sure which is the ideal transmission for your setup, please contact us.
