BGM Cylinder 150cc, Ø=57mm, stroke=57mm

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 grey cast iron cylinder has three overflow valves and is suitable for all wideframe engines with 57 mm stroke. On the 125ccm 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 foot seal spacer made of aluminium and the cylinder is flushed through a corresponding groove in the piston. Thus no modifications to the engine housing are necessary.

The cylinder helps the very old Vespas to get much more pull and final speed. A fast acceleration, even by today's standards, is the paradediscipline of the BGM PRO 150. 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 any loss of reliability.

The 23mm CP carburettor including BGM PRO intake manifold (see accessories) offers an ideal supplement.
