Malossi MP-ONE reed valve engine casing for models with Ciao-SI-Bravo-Boxer electronics
Piaggio Ciao/Si/Bravo/boxer
Pair of crankcases in silicon aluminum alloy die-cast and shot-blasted.
Integral Malossi project with reed valve intake, controlled by a large
4-petal valve.
They can be used with any thermal group, exhaust system, crankshaft, and fuel system.
Malossi reed valve crankcases are perfectly interchangeable with the
original ones and are equipped with a special intake manifold for the
original carburetor or an SHA 13/13 carburetor.
A specific fuel system has been made with a 19 mm carburetor and E12 type air filter, complete with all the parts for installation.
Given the very limited insertion spaces in Piaggio frames, it was
necessary to create a super compact engine, and the great effort of
our technicians is once again crowned with full success.
The goals achieved are: highly technical product, robustness,
simplicity, ease of assembly, excellent operating result
without modifications (everything connects as in the original engine).
The large 4-petal composite fiber reed valve ensures a
smooth and progressive intake that optimizes the torque curve starting
from the lowest
