The POLINI 135cc is an all-rounder, suitable for all applications: from the relaxed plug-and-play city cruiser with 19/ 24mm carburettor on a disc valves, to the heavily modified cylinder, membrane inlet and 30mm carburettor.

The POLINI is THE entry cylinder into the famous ESC (Euro Scooter Challenge) racing series. Successful for years, with countless winners of tough duels and racing battles. This is simply the optimal basis for cylinder modifications or conversions. 7 transfer ports combined with a solid ASSO piston equipped with 1.5mm thick ductile cast iron rings make up to 12.2 PS possible without any extra modifications.
