Description
Original clutch type of the Vespa PX125: Ø108mm – 6 springs, 21 teeth.
This still has the so-called small clutch type with 108mm diameter and 6 springs. With 21 teeth it has the middle pinion which can be used in combination with all original primary gears (65,67 or 68 teeth).
Due to the modular design of the PX motors it is possible to use this type of clutch on all other large frame motors like the PX80 or PX150.
Recommended for all PX80 engines with a larger cylinder.
Cylinders with a capacity of 177cc and above should use a clutch with 22 teeth and should generally be converted to the larger clutch type with 115mm Ø. These can cope with the higher torque permanently.
TIP: Especially recommended is the BGM Superstrong clutch which is not only indestructible but also very easy to operate.
Without modifications the coupling can be installed in the following models:
Note: Should this type of coupling be used in older vehicles such as VBB, VNB, GT, GTR orIf this type of clutch is to be used in older vehicles such as VBB, VNB, GT, GTR or similar, the clutch spacer plate must also be replaced with that of the newer models (3.3mm instead of 1.5mm, see accessories).
Newfren is the Italian original equipment manufacturer for Piaggio and our first choice in the field of standard 6 and 7 spring clutches. Reinforced version with 4 discs and thus increased friction surface. Often does not separate as cleanly as the 3-disc version, but can transmit more torque.

As lubricant we recommend BGM Pro Street gear oil (BGM2025, complies with specification API GL-3).
