The great success achieved with the Thor paramotor engines hasn’t stopped the research and development of the Polini Motori technical department. Light, reliable, compact and powerful here it is the new range of “Polini Thor 190 Light” engines: three different models that among them stands out the new one with centrifugal clutch.

It’s a two stroke 193cc engine, with really reduced weight of 13,2 kg, transmission with belt gearing-down, compact dimension but powerful. It has been designed to meet the needs of the “pilots” who are willing to use a really performing engine of reduced weight. Project and approval required many tests and many hours of flight to grant the best performance and safety requirements. For the most exigent pilots a model with electric starter and a model with centrifugal clutch and flash starter are available.
TECHNICAL FEATURES
PURE TECHNOLOGY 
Polini Thor 190 engine features advanced technical solutions; dimensions, power torque ratio, reduced vibrations, performance of climb, innovative and compact design, but, above all, everything has been studied to grant the best weight-power ratio, studying every single part in order to reduce its weight.
TRANSMISSION 
Belt transmission with 2,83 reduction ratio. To reduce vibrations a new crankshaft with distributed and optimized rotating weights has been designed for this specific transmission system. In order to resist to the belt strength, a special bearing has been housed on the transmission case side. It can stand a transversal load 10 times higher than the standard roller bearings. It lets the belt have a constant stretch.
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 7400 rev/min. even at the maximum working temperature. The cylinder liner has a nickel-chrome coating for the best piston sliding. The piston is gravity die-cast in light alloy at high silicon content with 2 chromed and nitride steel rings.
