Description
Clutch cover complete BGM PRO Superstrong CNC ULTRALUBE - Vespa Largeframe 1958-1962
More than just a cover: The BGM PRO Superstrong CNC ULTRALUBE cl utch cover for early Vespa Largeframe models (1958 to 1962) comes here as a completely pre-assembled kit - including clutch arm, clutch arm spring, release lever, separating mushroom, O-rings and mounting material. The silver CNC design enables conversion to the modern PX clutch type and at the same time creates space for reinforced and CNC-machined sports clutches.
Why this cover is particularly important for early largeframe engines
The first Vespa largeframe engine cases (VBA, VBB1, VNA2, VNB1-3, VGLA, VGLB) have a flatter design in terms of the distance between the sealing surface of the clutch cover and the crankshaft bearing. The originally installed, flat clutches are more difficult to obtain and are often already at their limit with moderate power increases. The BGM PRO CNC cover is deliberately designed higher for these engines and allows the use of standard PX/Cosa clutch types including modern CNC versions - without milling work on the housing. The standard thin washer (approx. 1.5 mm) is still used.
Complete and ready to fit
✔️ CNC clutch arm with two cable pull positions: more disconnect travel or less manual force
✔️ Integrated ULTRALUBE oil guide reliably lubricates the disconnect mushroom and pressure bearing
✔️ Higher inner contour for oversize Sport and Race clutches
✔️ Specially for Vespa Largeframe 1958-1962 (conversion to PX clutch type)
ULTRALUBE - Lubrication where it counts
Many machined out series covers lose the oil supply for the separating mushroom during machining. The BGM PRO ULTRALUBE coverguides the transmission oil specifically to the release bearing and pressure plate. This reduces wear, improves the separation behavior and ensures high long-term stability - especially in combination with powerful clutch springs and high-torque engines.
Conversion to clutch type PX
Thanks to the higher design of the cover, a PX/Cosa clutch pack can be installed in the early Largeframe engines. This means that robust Superstrong and other CNC clutches are available which are much better suited to the increased performance level of modern setups than the flat original clutches. The inside of the cover is contoured in such a way that the standard oversize Sport and Race clutches can be fitted without additional reworking of the cover.
