Description


Together with the large primary wheel, the clutch pinion forms the so-called primary reduction. Here, the transmission ratio can be changed by simply replacing the clutch pinion.
Those who cannot manage this can also replace the primary wheel.

For the latter option, however, the engine must be opened completely, for the clutch pinion, however, it is sufficient to remove the clutch cover together with the clutch.

There are three primary wheels that were originally installed.

  • 65 teeth: PX200, Rally200
  • 67 teeth: Sprint Veloce, Super, GT, GTR, TS
  • 68 teeth: PX80, PX125, PX150, all Cosa models.

The fewer teeth the primary wheel has, the longer the possible reduction.
The fewer teeth the clutch pinion has, the shorter the possible reduction.

The following combination can be used:

  • 65Z = 23Z
  • 67/68Z = 20Z, 21Z, 22Z

There are now (from z.The 200cc models (except Cosa) use the combination 23/65, which is a very long gear reduction and can be shortened by one tooth for sporty engines. There is a special BGM pinion with 22 teeth, suitable for the primary gear with 65 Z. The clutch pinion with 22 teeth for the 67/68Z primary gear should not be combined with a 65 tooth primary gear.

The 23/65 primary can be extended for very high torque engines with a 24 tooth BGM special pinion. Ideal for Polini 221 and others.


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