Vespa PX200 Rally200 MALOSSI 210 SPORT MHR BGM Original Cylinder Base Spacer Gasket - 0.5mm

The MHR cylinder has proven to be a very grateful candidate for a higher position, despite the much more generous flushing cross sections than its predecessor. The prerequisite is an environment corresponding to the cylinder, such as a large carburettor with a corresponding intake system and a powerful exhaust system.

Thanks to the good flushing system of the MHR, the cylinder loses little power in the pre-resonance range (the range before the exhaust starts to assist), even with a strong raising.

Please remember that a dimension corresponding to the raising is removed from the head. Otherwise the compression and power will decrease dramatically. If the cylinder is operated with a crankshaft with 60mm stroke, the raising of the cylinder is obligatory and a simple means to realize the additional stroke (3mm = 1,5mm spacer at the base) without additional head gasket.
