Description

BGM PRO Superstrong - the original
Extremely durable clutch, easy to use - Made in Germany
The Superstrong clutch combines extreme durability, absolute reliability and easy operation.
It is the foundation of any solid engine tuning.
The solid, CNC machined clutch basket has an excellent concentricity as well as an enormously high torsional stiffness. Thus, it offers perfect clutch engagement behavior with clearly defined grinding point and clean separation. It can be used by touring riders who value high quality, as well as by ambitious racers who are looking for an extremely resilient and stable clutch.

PERFORMANCE

The ready-to-install clutch is tuned for a power range up to approx. 20HP / 22Nm by means of the mounted clutch springs. Reinforced springs (available separately, BGM PRO XXL) extend the power range of the clutch to over 40hp. At the same time it still remains easy to operate. However, please also note the information regarding the helical 24 tooth sprocket under the point 'Gearing'

VEHICLES
The bgm Pro Superstrong replaces any conventional clutch type as used in the
Vespa large frame models with rotary intake valve control from about 1967.
Can be used in Vespa GL, Super, Sprint, Sprint Veloce, GT, GTR, TS, Rally, PX, Cosa and T5.

MODIFICATIONS
Vehicles with less than 180cc (from factory) need the clutch cover of the 200cc models, unless the original existing clutch cover is to be modified.
Vehicles prior to 1998 require minimal modification to install the Superstrong clutch (see documents under "Downloads").

COATING TYPES CR
In the CR version we offer the clutch with the Honda CR80/VFR400 type of coating.
These have a larger effective radius, less weight, wider plates and a very strong lining material. The advantages are a lighter clutch that separates faster yet is extremely durable.

TENSIONS
Clutches with straight-toothed pinions can only be combined with the corresponding straight-toothed primary gear. For this purpose, the motor must be fully opened. The extra long primary reduction gears based on the 62/63 tooth primary gear are only available with straight teeth. The high torque of the motors that require such a long reduction is fed directly into the gearbox via straight gearing, without exerting lateral forces on the bearing of the auxiliary shaft. Due to the precise manufacturing the straight geared drives are nevertheless as quiet as the helical geared ones.

Please note that we recommend a straight-toothed primary drive for engines with a power above approx. 25HP/25Nm. The straight toothed drives offer maximum safety. With the same possible reduction (by using a different pinion pairing) they have a much more stable tooth base in direct comparison to the helical geared drives. Instead of a helical-toothed 24/65 reduction, we recommend, for example, the straight-toothed 23/63 BGM primary. The reduction ratio is almost identical in both cases, but the 23/63 is the perfect choice for sporty engines because it is virtually indestructible. If the 23/63 ratio is too short for you, you can choose a 62 tooth primary gear and extend it even further with the individually available clutch pinions (with 24 or 25 teeth).

The helical 24 teeth special pinion is perfect for plugged setups such as Polini 210 or Malossi Sport. With this, the available speed band can be stretched again and a higher top speed can be achieved. However, we expressly do not recommend it for heavily revised engines whose power is above 25PS/25Nm. This is not possible due to the design of the 24/65 pinion pairing.

TRANSLATION
A primary drive consists of clutch (pinion) and primary gear.
Piaggio has already combined 65, 67 and 68 tooth primary gears with different clutch pinions at the factory.
This makes it easy to adjust the overall gear ratio to the engine power.
A distinction is made here between 67/68 and 65 teeth.
Due to the different so-called gear module, 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. 24Z*

EXAMPLES

Longer ratio:

PX80/PX125 riders use a clutch with 22 or 23 teeth for ratio extension (suitable for primary wheel 67/68)
PX200/Rally200 riders use a clutch with 24 teeth for ratio extension (suitable for primary wheel 64/65)

Shorter ratio:

PX200/Rally200 riders use a 22 tooth clutch (suitable for primary wheel 64/65) for ratio reduction

TIP
EXTRA LONG
DELIVERY

Included is the complete ready to install clutch with bgm PRO Cosa clutch plates and ten BGM PRO XL springs. A new o-ring for the clutch cover, the crescent wedge and a new clutch nut are also included. We use a nut with clamping part (MBN13023, T2, strength class 10, DBL9440.40) because we have had the best experience with this in racing with over 40HP 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).
