THOR 190 EVO
Thor 190 Evo engines feature new technical solutions studied to improve the weight/power ratio, stability and grant an unforgettable flying experience.
Belt transmission with 2,83 reduction ratio. Special composition to have a better grip, less servicing, more stability, longer life and immediate power output.
The exhaust system is completely hand made for a better product quality. Compact design and contained dimensions. Reduced overall dimensions for a better aerodynamic. Low noise level.
SPECIFIC POWER UNIT
The power unit with 193cc displacement, 64mm bore and 60mm stroke, is cast in light alloy. It offers the maximum performance with 27 hp power at 8000 rev/min. even at the maximum working temperature.
The exhaust system is completely hand made for a better product quality. It is divided into two shells. The exhaust manifold is with spherical coupling and it is fixed on rubber suspensions that grant an incredible duration.
