This type of coupling is almost identical to the later PX models, however, the height of the clutch is different due to the other clutch-side crankshaft stub (Sprint: 34mm / PX: 32.5mm). Therefore the height of the clutch pinion itself is also different (Sprint: 11mm / PX: 12mm). Therefore this pinion can only be used in the motors with the old type clutch, not in the PX motors.
*Attention: In some of the above mentioned models the new PX clutch type with 32,5mm height was already used in a second series (Sprint: 34mm / PX: 12mm).
The 22 tooth sprocket fits on the 67 and 68 tooth primary wheel.
It does not fit on the 65 tooth primary wheel of the 200cc models.
