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.
