Malossi VR-One Reed Valve Engine Casings - Vespa P200
The VR-One has an intake port with a redd valve inlet and is primarily aimed at tuners who attach importance to a high power yield. The reed inlet is moved further in the direction of the cylinder so that full cheek shafts can also be used sensibly (the crank cheeks are no longer in the way of the gas flow).
Intended for use with a Malossi 210cc Sport or 210/221cc MHR cylinder. The engine housing is already made to fit the overcurrent channels, no further adjustments are necessary. Of course, all other cylinders can also be used on these housings.
The biggest novelty of the Malossi motor housings is the renunciation of loose motor screw bolts as well as the middle seal made of sealing paper. The housing is now assembled with M8 Allen screws, the sealing is done with temperature stable sealing compound (TIP: anaerobic hardening sealing compound from Loctite).
The housings have reinforcements at all neuralgic points (auxiliary shaft, fivefold bolted crankcase, swing arm and shock absorber mount). More material has been planned for the sealing surfaces, so tuners can let off steam to their heart's content. The crankshaft bearing on the alternator side is now much bigger and more stable (25x52x15mm instead of 25x38x15mm).
Pre-assembled silent rubbers on the engine and shock absorber mounts are included with both types.
