Power is supplied even at a low rev range and the kits offer enough torque which allow you to ride even with longer ratios. The power development is very constant which means that the RaceTour engines fell like a genuine Innocenti 200 engine but with double the power.
Like for the genuine cylinder, the carburettor is positioned at the left side. The frame or the other parts require no modifications. Therefore the RaceTour cylinder is also ideal those who want to keep the Lamnretta look unchanged but, at the same time, don’t want to forgo performance.

The springs are available in the following versions:

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

SCOOTERS

The bgm Pro Superstrong replaces the common clutch type used in all scooters of the Lambretta LI. The clutch fits therefore Lambretta LI, LI S, SX. TV (series 2-3), DL/GP models.

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

The item includes:

  • CNC rear sprocket 46 or 47 teeth
  • CNC clutch spider
  • CNC pressure plate
  • Adaptors to use the pressure plate with Li/SX and dl/GP engine cover

The clutch pressure plate and spider can be used with any other aftermarket 5 and 6 plate rear sprockets. As long as these are made to the original Innocenti measurements it is a straight fit. If not made to this spec some modifications might be needed.

TIP: We recommend to use a washer (available in our online shop) to space the clutch. The washer is placed under the sprocket and is available with a thickness of 0.8-1.6 mm. The overhang of the BGM hub (clutch spider) to the BGM sprocket is in the tolerance range from 0.10mm to 0.12mm.
