Pressure die-cast, shot-blasted crankcase in aluminium-silicon alloy. Complete Malossi project with lamellar intake,
controlled by a reed valve with four petals.
Available in 2 versions which include the entire range of Piaggio and Gilera motorbikes:
They can be used with any cylinder kit, exhaust system, crankshaft and fuel system.
- electronic ignition
- magneto ignition
Malossi lamellar crankcases are fully compatible with the original ones and are fitted with a special inlet manifold for
the original carburettor or a SHA 13/13 carburettor.
A specific fuel system has been developed with a 19-mm carburettor and type E12 air filter, including all the details
Due to the restricted assembly space on Piaggio frames, an ultracompact
engine had to be developed. Once again, our technicians
passed the test with flying colours. The goals reached are: a highly
technical product with a sturdy, simple, easy-to-assemble design;
resulting in exceptional operation with no need for modifications
(everything is connected in the same way as the original engine).
The 4-petal composite fibre reed valve guarantees a regular, steady
intake which optimises the torque curve, starting from lower rpm
and allowing maximum power output.
The gas passage has been totally revised
thanks to a pipe which can grant a greater
charge quantity together with less leaks from
the valve to the cylinder.
The introduction of two new gas slides under the cylinder lets the
crankcase be better connected to high performing cylinders.
The new spiral case constrains gas to do a calculated route much
more addressed to the cylinder cooling fins thus warranting
the cylinder kit functioning at the best rpm even in the heaviest
Crankcase fitting is now easier thanks to a high precision
centering achieved by means of both calibrated bushings
and newest slots whose housings totally incorporate
the cylindrical head screws which can be screwed by a
simple Allen key.
In order to achieve remarkable torque and power values, the structure has been entirely strengthened with specific
shims in the more stressed parts.
The Malossi project makes the work of mechanics easier, but still leaves large space to the imagination of two-stroke
motorcycle fans who want to showcase their technical skills.
