The latest version of the smallest paramotor engine of the Italian factory comes with an original air filter and new carburetor setting. The Polini Thor 80 is a compact motor that weighs in at just 11.1 kg, featuring liquid cooling system. It has an aluminium cylinder, a displacement of 86 cc, and power of 17.2 HP for 10450 rpm.

According to Polini, the new air filter of compact dimensions was especially designed “to exploit the power at best and fully optimize the performance” of the Thor 80, and it also reduces the noise. The filtering element ensures maximum air cleaning features.

The new carburetor setting provides more homogeneous and linear power output at every rpm.

The small radiator with “unique drawing of the air grill ensures the best cooling features”, say at Polini. The special pipe and the radiator are integrated and fixed directly to the engine. The system has forced cooling with a valve directly on the crankshaft. The circulation of the cooling liquid is ensured by a pump on the reduction group.
