SpeedEngine racing case from Polini for your Piaggio Ciao, Si, Bravo and Boxer moped / moped.
This version of the engine case is designed for contact ignition and cannot be used for electronic ignition.
The engine housing impresses with its clean finish and is perfect for cylinder kits with a piston diameter of up to 46 mm.
Ideally, you should use a Polini cylinder. However, the overflow ports of the Malossi cylinder kits (from 2021) or those of the DR 43 mm racing kit also fit quite well.
The intake manifold is designed for Dell'Orto SHA type 3 carburettors with up to 13 mm passage.
The intake timing is already very long ex works. Therefore, the engine block can also be operated with the original crankshaft.
If you want to get even more power, we recommend using a racing crankshaft.
With the optionally available swiing intake manifold, it is also possible to operate larger carburetors than a 13/13.
Matching parts such as racing cylinders, racing shafts or our swiing intake manifolds with matching carburetors can be found in the accessories section.
