The Motoforce Racing Evolution Clutch (MF80.105) is designed for scooter enthusiasts and racing hobbyists running Minarelli engines who want to optimize their transmission engagement. Its primary benefit is the ability to adjust spring preload without dismantling the unit, providing significant time savings during tuning; however, users should be aware that this is a performance-oriented racing part that may require more frequent maintenance than stock components.

It is designed for Minarelli engines utilizing a 105 mm clutch bell housing. Always verify your specific model's housing diameter before purchase.
The spring preload is adjusted via an Allen screw on the back, so you do not need to dismantle it from the converter for preload changes.
The springs have different tension rates, which dictate the RPM at which the clutch engages. The stiffer springs generally raise the engagement RPM.
While it can be used on the street, it is a racing part designed for performance. It will likely engage much more aggressively than a stock clutch.
You will need standard socket tools for the transmission cover and a clutch tool to remove the large central nut on the torque converter.
Increase the spring preload using the rear Allen screw or install the stiffer set of springs provided in the kit.
Check that the clutch bell is not warped and ensure the friction pads are wearing evenly.
Inspect the friction pads for glazing or excessive wear and check that the clutch bell diameter matches the 105 mm requirement.
To install the MF80.105, ensure your scooter utilizes the 105 mm Minarelli bell housing. Always ensure the clutch nut is torqued to manufacturer specifications. For maintenance, check the condition of the friction pads every few track days to ensure they have not glazed over. Use the rear Allen screw to make small, incremental changes to preload, testing the bike after each adjustment to find the ideal engagement point. Keep the clutch area clean and free of heavy grease or belt debris, as foreign material can cause slippage or uneven wear.
