POLINI THOR 190 HF
As its Thor 200 HF older brother, the Polini Thor 190HF has been developed by the R&D team using the new 3D modeling software systems and flow dynamic simulation. The result of this research and the introduction of the innovative HF System grant better cooling improving the performance of the Thor 190HF. Polini THOR 190 HF engines feature: 193cc displacement, reduced weight till 13,6 kg if equipped with Titanium exhaust system (available as an optional). Technical features: “HF” COOLING SHROUDThe new design of the “COVER” cooling shrouds optimizes and accelerates the incoming flows and increases the exit power towards the propeller.Together with the air forced system it grants great performance in terms of cylinder cooling. SPARK COOLING SYSTEMSCS is the innovative cooling system of the spark plug that lows the working temperatures in the point of highest warm and in the burning chamber, eliminating the events of over-heating. Polini SCS system reduces the EGT temper
