Description

BGM PRO Superstrong - the original
Extremely durable clutch, very easy to use - Made in Germany
The Superstrong clutch combines extreme durability, absolute reliability and easy operation.
It is the basis of every solid engine tuning.
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.

PERFORMANCE
The ready-to-install clutch 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 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.

COVER TYPES CR
In the CR version we offer the clutch 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 that separates faster and yet is extremely resilient.

TOOTHINGS
Clutches with straight-toothed pinions can only be combined with the corresponding straight-toothed primary gear. 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 into the gearbox via straight toothing without exerting lateral forces on the auxiliary shaft bearings. Due to the precise manufacturing, the straight-toothed drives are nevertheless just as quiet as the helical-toothed drives. 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 ensure maximum stability.

EXAMPLES

Longer gear ratio:

PX80/PX125 Drivers use a clutch with 22 or 23 teeth (suitable for primary wheel 67/68)
PX200/Rally200 Drivers use a clutch with 24 teeth (suitable for primary wheel 64/65) to increase the gear ratio.

Shorter gear ratio:

PX200/Rally200 drivers use a clutch with 22 teeth (suitable for primary wheel 64/65) to shorten the gear ratio.

TIPP
For the greatest possible gear ratio range, simply install the special BGM 64 tooth primary wheel (motor must be completely opened for this). Then, by simply changing the clutch pinion, the engine can be reduced in size to suit a tame 177cc cylinder up to a torque steamer.
EXTRA LANG
Engines with a lot of torque and early power peak choose the straight-toothed clutches that also require a straight-toothed primary wheel (also available as a set). This allows very long gear reductions to be achieved. Ideal even if the overall gear ratio is too short for very sporty engines with a modified auxiliary shaft and shorter gear steps (e.g. MHR). Also an option if the actual gearbox is very short (PX80) or the gear ratio is too low due to a small wheel diameter (PX200 engine with 8 inch tyres in Oldie).
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, the half moon wedge and a new clutch nut are also included. We use a nut with clamping part (MBN13023, T2, strength class 10, DBL9440.40) as we have had the best experience with this nut in racing with over 40PS shaft power. Tightening torque 70-75NM. We do not recommend other locking devices such as Nordlock, corrugated spring washers (DIN137) or serrated lock washers (DIN6798).

(US)

As lubricant we recommend BGM Pro Street gear oil (BGM2025, corresponds to specification API GL-3).
