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 fuel system has a Polini CP carburetor Ø21mm with manual pump for the refilling of the fuel circuit. The fuel system also has a tank for the fuel recovery, which allows to empty the fuel from the bowl, minimizing losses.
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.
The barrel has a nickel-siliceous coating, extremely resistant to wear and abrasion. The light alloy gravity-cast piston at high siliceous content has 2 chromed piston rings of 1 mm. Bore for stroke 50 x 44 mm and compression ratio 14:1.
The Thor 80 has a dry clutch, reduction ratio 3.58 with helicoidal teeth gears in oil bath. These features grant a higher safety during the pre-flight phases, according to the manufacturer.
The engine comes with silent-blocks made in a special ERGAL ultra-light alloy, and it is delivered with CHT sensor to measure the temperature.
The Thor 80 fixing points to the frame are the same for all the range of the Polini Thor.
