Lambretta Clutch assembly (kit) 47 tooth, 6 plate, bgm

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 by means of the mounted soft clutch springs (BGM8010W) for a power range up to approx. 20PS / 25Nm. Reinforced springs, which are available separately, extend the power range of the clutch to over 40hp. Available are the spring types:

• BGM8010W - soft (k=4,7N/mm)
• BGM8010L - medium (k=6,8/mm)
• BGM8010F - hard (k=13,8/mm)

VEHICLES
The bgm Pro Superstrong replaces the traditional clutch type used on the entire Lambretta LI family of vehicles. Thus suitable for Lambretta LI, LI S, SX. TV (series 2-3), DL/GP models.

All CNC machined parts of the clutch are made of 42CrMo4.

Included in delivery are:

• CNC rear sprocket with either 46 or 47 teeth
• CNC clutch spider
• CNC pressure plate
• Adapter to use the pressure plate with both Li/SX and dl/GP engine covers
• CNC machined cover plate with shoulder to ensure enough air between cover plate and kickstarter shaft
• Six clutch plates
• Five 1.2mm steel discs
• Ten clutch springs, BGM8010W (k=4.7N/mm, soft)
• bgm PRO clutch bushing

The clutch pressure plate and spider can also be used with all other five and six disc clutch pinions. As long as the pinions are within Innocenti tolerances, this will fit without reworking the parts. For such combinations, especially the protrusion of the clutch spider should be checked.

TIP: Order an equalizing washer for spacing the clutch. This is installed under the clutch pinion and is available in thicknesses 0.8-1.6 mm. The protrusion of the BGM hub (clutch spider) to the BGM pinion is within the tolerance range of 0.10mm to 0.12mm
