Tuning cylinder 150ccm BGM PRO suitable for Vespa VM, VN, VB1, VGL1, VL1
BGM PRO cylinder with 150ccm at 57 mm stroke suitable for all 2-channel engines.
The cast iron cylinder has three overflows and is suitable for all wideframe engines with 57 mm stroke. On the 125cc engines with 54 mm stroke the cylinder with the 57 mm crankshaft also fits without problems.
The third channel on the cylinder is closed by a supplied aluminium foot gasket spacer and the cylinder is scavenged via a corresponding recess in the piston. This means that no modifications to the engine housing are necessary.

Stroke: 57 mm
Piston: Ø = 57 mm
Piston rings: 2 x 1,5 mm
Cylinder material: cast iron
Cylinder head: CNC milled from solid aluminium with additional cooling fins at the bottom

The cylinder helps the very old Vespas to significantly more pull and top speed. Quick acceleration, even by today's standards, is the BGM PRO 150's main discipline. 8-10 hp are available at the rear wheel, depending on the configuration, and a cruising speed of 90 km/h and more is possible without sacrificing reliability.
The 23mm CP carburettor with BGM PRO intake manifold (see accessories) is the ideal complement.
