The proven bgm SUPERSTRONG clutch is now also available for the Vespa GS150/GS160 and SS180 models.
Ready-to-fit clutch for your Wideframe Vespa
The bgm PRO clutch is supplied ready to fit. The scope of delivery includes
the assembled clutch,
a new lock washer,
clutch cover gasket and
half-moon wedge
We also recommend replacing the pressure plate and the separating mushroom, available here in a practical set! The Superstrong GS clutch replaces the standard clutch of the GS/SS models 1:1 and can generally* be used without further modifications. The clutch is available with 22 teeth (as original) or with 23 teeth (longer reduction ratio). Helical teeth for use with the standard 67-tooth primary wheel.
The bgm SUPERSTRONG 2.0 Ultralube clutch combines:
extreme durability,
absolute reliability and
easy operation
It is the basis of every solid Vespa engine tuning. The CNC-manufactured clutch basket has excellent concentricity and extremely high torsional rigidity. The Vespa clutch therefore offers perfect engagement behavior with a clearly defined grinding point and clean separation of the clutch linings. It can be used by touring riders who value high quality as well as ambitious racers who are looking for an extremely durable and stable clutch.
ULTRALUBE
The latest generation of Superstrong clutches now features an innovative new technology: Ultralube. Ultralube delivers gear oil (through precisely defined holes and centrifugal force) both into the highly stressed hub profile (between the clutch basket and clutch hub) and to the clutch linings themselves. This technology, which is unique in the Vespa sector, makes the legendary Superstrong 2.0 clutch even more stable than it already is. A clutch designed for eternity.
PERFORMANCE
The ready-to-install clutch is tuned for a power range of up to approx. 20 hp / 22 Nm by means of the installed clutch springs. Reinforced springs (available separately, bgm PRO XXL Reinforced clutch spring) extend the power range of the clutch to over 40 hp. It still remains easy to operate.
SCOPE OF DELIVERY
The scope of delivery includes the complete ready-to-install clutch with bgm PRO Cosa clutch facings and ten BGM PRO XL springs. A new O-ring for the clutch cover and a new half-moon wedge are also included.
RECOMMENDATION
We also recommend a low-alloy transmission oil of the API GL3/GL4 classes for high-performance engines in order to prevent the clutch from slipping even under extreme loads. This also applies to our bgm Superstrong clutches. The old engine oil specification SAE30 corresponds to the current transmission oil specification SAE 85W/90. As a lubricant, we recommend the bgm PRO Street gear oil (BGM2025, corresponds to specification API GL-3). * In some cases it may be necessary to rework the clutch cover and arm slightly, see instructions & Video:
