ULTRALUBE

The latest generation of Superstrong clutches now has an innovative new technology: Ultralube.
Ultralube pumps (through precisely defined bores and centrifugal force) transmission oil both into the highly stressed hub profile (between clutch basket and clutch hub) and onto the clutch linings themselves.
This in the Vespa area unique technology makes the legendary Superstrong 2.0 clutch even more stable than it already is. A clutch designed to last.

PERFORMANCE

The ready-to-install clutch is designed for a power range up to approx. 20PS / 22Nm by means of the mounted clutch springs. Reinforced springs (sold separately, bgm PRO XXL Reinforced clutch spring) expand the performance range of the clutch to over 40 hp. It is still easy to operate.

RECOMMENDATION

We also recommend a low-alloy gear oil of classes API GL3 / GL4 for high-performance engines in order to prevent the clutch from slipping even under extreme loads. This also applies to our bgm Superstrong couplings. The old engine oil specification SAE30 corresponds to today's transmission oil specification SAE 85W / 90. We recommend this as a lubricant bgm PRO Street gear oil (BGM2025, corresponds to specification API GL-3).

Vespa Cosa clutch upgrade

SOLID BASE BRACKET

The linings use an aluminum carrier, the lugs of which have a large contact surface for the clutch basket. This makes the coverings very stable over the long term. The slow shearing of the tabs, which often occurs with conventional decks with steel girders, is completely eliminated due to the large contact surface. The aluminum also makes the coupling more thermally resilient. This is a great advantage in extreme situations (e.g. starting with a heavy load on a steep mountain pass), but also offers a reassuring reserve in everyday life. The width of the flaps is made to fit precisely, so that the pads are almost free of play in the basket.

DURABLE AND GRIPPLE MATERIAL

The lining material for the clutch discs is the same for the bgm PRO TOURING aluminum linings high quality sintered material as used for the CR80 racing pads. Due to the larger contact surface in the TOURING variant, the coupling is softer and not aggressive. The large support surface also improves durability.
