Thor 260

The new engine was designed and developed to offer usability and versatility of use with the aim of offering ever greater reliability and reducing maintenance costs. Conceived to be the ideal engine in the world of long-distance flights, the Polini Thor 260 can be defined as a true "grand tourism" which combines high performance with great regularity of operation, for a versatility that allows it to always express itself at maximum. Fluidity and regularity are essential requirements for enjoying long journeys. The Polini Thor 260 is equipped with liquid cooling and has been designed to always offer fluid, regular, progressive delivery and flight comfort made optimal by the work of reducing vibrations via the balancing countershaft.

Safety in flight and attention to consumption

 The Polini THOR 260 was born from the desire to create a balanced "cruise" engine, for an increasingly demanding market in terms of reliability and consumption. With a weight of 21 kg (including radiator), the new Polini THOR 260 guarantees an excellent compromise of stability and power.

 With its 36 horsepower at 8000 RPM the Polini THOR 260 is capable of offering up to 105 kg of static thrust with a 160 cm propeller.
 Consumption is only 3.5 liters per hour at 4500 rpm, which corresponds to approximately 30 kg of static thrust, average level flight value.

In the Polini THOR 260, cooling is guaranteed by a compact radiator which allows for reduced weight during take-off and greater aerodynamics in flight.

Polini Motori has decided to maintain the same fixing system on the entire range of THOR paramotors. Manufacturers can thus produce a chassis that can accommodate the entire range, significantly reducing both production costs and delivery times. A plus point also for the riders themselves, who can change THOR models without having to replace or modify the chassis.

The Polini THOR 260 is equipped with an electric starter combined with a manual "flash starter". The excellent reliability/power compromise allows the THOR 260 maximum versatility for use on single and two-seater trikes and delta trikes. The new THOR 260 is available with a choice of two different reductions: 2.8 (recommended for propellers up to 140 cm) and 3.2 (for propellers over 140 cm).
