Vespa PX 125 150 Super Sprint GL Rally BGM PRO Superstrong Cosa 2 Clutch - 20T for 67/68 Tooth

Vespa PX 125 150 Super Sprint GL Rally BGM PRO Superstrong Cosa 2 Clutch - 20T for 67/68 Tooth

BGM PRO Superstrong 2.0 CR - the original, now with Ultralube
Extreme loadable coupling, very easy to use - Made in Germany

The Superstrong 2.0 CR coupling combines extreme durability, absolute reliability and easy operation.
 The solid, CNC manufactured clutch basket has an excellent concentricity as well as an enormously high torsional stiffness. It thus offers perfect clutch engagement with a clearly defined grinding point and clean cutting. It is suitable for the touring rider who values high quality as well as the ambitious racer who is looking for an extremely strong and stable clutch.

ULTRALUBE
The latest generation of Superstrong 2.0 CR clutches now features an innovative new technology: Ultralube.
Ultralube pumps (through precisely defined bores and centrifugal force) gear oil both into the highly loaded hub profile (between clutch basket and clutch hub) and to the clutch linings themselves.
This technology, unique in the vespa sector, makes the legendary Superstrong 2.0 CR clutch even more stable than it already is. A clutch, designed for eternity.

PERFORMANCE
The clutch is supplied ready for installation and is tuned for a power range up to approx. 20PS / 22Nm by means of the mounted clutch springs. Reinforced springs (available separately, BGM PRO XXL) extend the power range of the clutch to over 40 HP. At the same time it still remains easy to operate.

VEHICLES
The bgm PRO Superstrong 2.0 CR replaces every conventional type of clutch as used in the
Vespa large frame models with inlet rotary vane control from about 1967 onwards.
Usable in Vespa GL, Super, Sprint, Sprint Veloce, GT, GTR, TS, Rally, PX, Cosa and T5.

MODIFICATIONS
Vehicles with less than 180ccm (ex works) require the clutch cover of the 200ccm models, unless the original existing clutch cover is to be modified.<="" p="" style="box-sizing: border-box;">

COVER TYPE CR
We deliver the Supertrong 2.0 CR with the clutch facing type of the Honda CR80/VFR400.
These have a larger effective radius, less weight, wider plates and a very resilient facing material. The advantages are a lighter clutch, which separates faster and is still extremely resilient. The traditional cork linings with a wide contact surface offer no advantages whatsoever, which is why we no longer use them in the Superstrong 2.0 CR.

TOOTHINGS
Clutches with straight-toothed pinions can only be combined with the corresponding straight-toothed primary wheel. To do this, the motor must be fully opened. The extra long primary reduction ratios based on the 62/63 tooth primary gear are only available with straight teeth. The high torque of motors requiring such a long reduction is transmitted directly to the gearbox via straight teeth without exerting lateral forces on the auxiliary shaft bearing. Due to the precise manufacturing process, the straight-toothed drives are nevertheless just as quiet as the helical-toothed drives.

transmission
A primary drive consists of a clutch (pinion) and primary gear.
Piaggio has 65, 67 and 68 teeth primary gears already combined ex works with different clutch pinions.
 A difference is made here between 67/68 and 65 teeth.
Due to the different so-called gear modules, the following wheel/pinion combinations can be used.
Please note: BGM is the only manufacturer to offer different 22Z pinions for 67/68Z and 65Z primary gears. This is the only way to guarantee maximum stability.
