Malossi MP-One crankcase with electronic ignition Piaggio SI 50 2T

Pair of Malossi 5717514 crankcases in shot-blasted die-cast silicon aluminum alloy. Integral Malossi project with lamellar admission, controlled by a large 4-petal valve.
They can be used with any cylinder kit, exhaust system, crankshaft and fuel system.

Malossi reed valve casings are perfectly interchangeable with the original ones and are equipped with a special intake manifold for the original carburettor or a SHA 13/13 carburettor.
A specific fuel system was created with a 19 mm carburettor and E12 type air filter, complete with every detail for assembly.

Given the very small insertion spaces in Piaggio chassis, it was necessary to create a super-compact engine, and the great commitment of our technicians is once again crowned with full success.
The objectives achieved are: highly technical product, sturdiness, simplicity, ease of assembly, excellent operating result without modifications (everything reconnects as in the original engine).
The large 4-petal reed valve in composite fibers guarantees regular and progressive admission which optimizes the torque curve starting from the lowest rpm and allows maximum power to be delivered.
