Cylinder -POLINI cast iron 112 cc- Vespa V50, PK50
Part no.:
1010006
Description
Polini's 112 cc set is technically the big brother of the 102 and achieves its larger displacement by enlarging the bore to 57.5 mm. Compared to the 102, the 112 has a larger outlet cross section and a higher compression ratio. This gives it a performance that turns a fifties into a first class power package (Polini indicates 7,2 kW at 6500 rpm!).
In any case, a long transmission ratio combined with a 19 carburettor kit and a good exhaust like the LeoVinci is very useful.

The cylinder can of course also be driven with larger carburettors, such as a bgm PWK 24.
To enjoy the full power of the cylinder permanently, a skilled screwdriver hand is necessary. Should be driven with Super/Superplus.
