MALOSSI REED VALVE CRANKCASES

The Malossi VR-One MHR crankcase, for the Vespa PX200, provides the ideal foundation for your next performance reed valve engine.

Manufactured in Italy, this high-quality crankcase has been designed to withstand increased power with reinforcing webbing in key locations, and is supplied with main bearings for the flywheel side and for the drive side, which both use balls instead of rollers, and offer greater radial load tolerance and an additional resistance to axial loads, which is not possible with the original roller bearings. Dedicated seals are also supplied. The transfer ports have been machined to ‘match’ the range of Malossi PX200 cylinder kits, saving both time and money on porting work. Supplied with a reed valve manifold suitable for carburettors up to 30mm in size which has been designed for a much larger reed block (included) that is equivalent in size to a 6 petal block. Gone are the M7 bolts securing the crankcase halves together, and in their place M8 allen bolts now feature. Malossi have also redesigned the mating face to remove the need for a central gasket, (sometimes a cause of problems on high power motors), allowing the use of a gasket sealant in its place. The crankcase is supplied with engine mounting rubbers, cylinder studs, crankcase bolts, drain plugs and washers, reed valve inlet manifold, crank bearings and oil seals.

With Malossi’s heritage in Vespa tuning, the new crankcases are sure to be a very popular starting point for performance engine builders looking for excellent reliability, with an outstanding quality of finish.
