Details

Small upgrade kit for the primary ratio of all PV125, ET3, PK80-125 S/XL/XL2 motors. The set massively strengthens the primary drive and makes it durable even for powerful engines. The solid CNC-milled cover plate effectively prevents the thin standard plates from breaking through and thus keeps the shock absorber springs in place.

Ideal supplement to the BGM Pro Superstrong clutch
Reinforces the primary drive
Replaces the standard cover plates
Protects the entire drive train, especially the clutch
CNC reinforced: two-piece = easier installation
Fits all primary transmission ratios with standard shock absorbers (springs)
Useable with standard springs or reinforced BGM springs
Useable with all Vespa clutch types: V50/PV/ET3, XL1, XL2
Made from 42CrMo4
Hardened (nitrided)
Made in Germany

This evolutionary step of our popular HD primary kit now consists of only two components and thus considerably simplifies the assembly compared to the old version with loose sleeves and two cover plates. It is now also suitable for the clutch baskets of the XL2 versions. The kit does not fit the springless primary wheels of the 50cc models. Since these should also receive a longer gear ratio when the engine capacity is increased, the upgrade kit can be mounted in a new primary reduction ratio without any problems.

In principle such an upgrade kit should be used in every engine, not only in very powerful engines. The enormous torque of today`s engines also requires the use of reinforced shock absorber springs. This prevents the too soft springs from going on block and the noses of the clutch linings from getting into the basket.

Note: Depending on the manufacturer and tolerances of the primary used, it is possible that the CNC cover plate will touch the bearing seat or its bracing of the crankshaft bearing.
