Primary transmission kit Minarelli AM6 Racing Factory Bidalot

The manufacturer Bidalot Racing Factory brings us this complete kit for primary transmission, with 5 plates, for Minarelli AM6 engines.

With this kit, we change the main gear ratio from 20/71 to 19/67 to make the primary shaft spin faster and reduce the torque to the clutch.

Additionally, by completely modifying the bell and the clutch nut made from mass-cut aluminum, it is possible to install 6 clutch plates, instead of the original 4.

The clutch no longer slips, and all the power supplied to the crankshaft output will be transmitted to the wheel.

The kit includes:

• Primary transmission with 1 primary pinion Z = 19 teeth
• 1 water pump pinion.
• 1 primary drive wheel Z = 67 teeth mounted in the needle cage.
• 1 spacer.
• 2 needle cages.
• 1 CNC clutch housing.
• 1 CNC clutch nut.
• 1 set of 6 clutch plates + 5 smooth steel plates.
• 5 racing clutch springs.
• 1 set of screws.
