PRODUCT INFORMATION
An even more improved, modern, innovative engine, with an original and advanced air filter, especially planned to exploit the power at best and fully optimize the performance of the smallest paramotor produced by the factory in Bergamo.
Polini Thor 80 has an aluminium cylinder, a displacement of 86cc and a power of 17,2 hp for 10450rpm. 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 fuel system has a Polini CP carburetor Ø21mm. with manual pump for the refilling of the fuel circuit. Integrated on the engine support, it makes this function easier by keeping minimal overall dimensions. The fuel system has also a tank for the fuel recovery. This feature allows to empty the fuel from the bowl, in order not to have losses and make transport easier. As an alternative, the Walbro WG8 carburetor is available. 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.
