MALOSSI MHR "third support",
for MINARELLI horizontal 50cc
straight teeth, counter
supported incl. support
Tuned Minarelli motors tend to develop problems with vibration around the primary drive shaft, especially at higher revs. The 'Third Support' solution offered by MALOSSI employs a supplementary shaft bearing, located in the crankcase cover, to solve this problem in combination with a straight-cut 14/42 primary drive cog assembly. The primary drive shaft is provided with extra support by an additional bearing, positioned on the outer side of the crankcase cover. This results in a more efficient and effective CVT transmission system.
A 10 mm hole must be made in the crankcase housing cover. Detailed installation instructions are include with this kit and can also be viewed and downloaded on and from our website
