150cc BGM PRO tuning cylinder suitable for Vespa VM, VN, VB1, VGL1, VL1

BGM PRO cylinder with 150cc at 57 mm stroke suitable for all 2-channel engines.
The cast iron cylinder has three overflows and is suitable for all wideframe motors with a stroke of 57 mm. The cylinder with the 57 mm crankshaft also fits the 125 cc engines with 54 mm stroke without any problems.

The third channel on the cylinder is closed with an included aluminum foot sealing spacer and the cylinder is rinsed using an appropriate cutout in the piston. As a result, no modifications to the motor housing are necessary.

• Engine capacity: 150 cc

• Stroke: 57 mm

• Piston: Ø = 57 mm

• Piston rings: 2 x 1.5 mm

The cylinder gives the very old Vespas significantly more torque and top speed. Fast acceleration, even by today's standards, is the prime discipline of the BGM PRO 150. Depending on the configuration level, 8-10 hp is available at the rear wheel and a cruising speed of 90 km/h and more is possible without sacrificing reliability.

The 23mm CP carburettor with BGM PRO intake manifold is an ideal addition (see accessories).
