BGM ORIGINAL shift peg - Vespa PX old (1977-1983)

Precision you can feel when shifting gears: The BGM ORIGINAL shift peg is manufactured with special attention paid to the exact alignment of the shift arm and shift pad. For PX old gearboxes (model years 1977-1983), the outer surface of the shift pad in 3rd gear is exactly 1.5 mm above the sealing surface of the shift detent - this ensures clean gear changes, defined engagement and a securely engaged gear, even under load.

Why PX old? Quickly identified - without opening the engine

FAQ - frequently asked questions about the BGM ORIGINAL gear lever (PX old)

No. PX old and PX Lusso use different geometries. For Lusso gearboxes (from approx. 1984) please use the appropriate Lusso version.
It is the reference dimension for the correct position of the shift block and shift arm. This ensures that the gears engage precisely and remain securely engaged even under load.
Remove the shift lever and check the wrench flat on the shift bolt: 13 mm = PX old, 17 mm = PX Lusso.
Adjust the shift cables so that there is no play and check that all gears engage properly. The 1.5 mm reference dimension helps to verify the correct position.

Note: This version is specially designed for PX-alt gearboxes 1977-1983. For Lusso gearboxes from 1984 onwards, please select the corresponding BGM version.
