Liquid Cooling System

The brand new Polini THOR 250 features a liquid cooling system, that grants an extraordinary steady power output and better performance at every rpm.

Aluminium cylinder

The die cast light-alloy aluminium cylinder grants a better thermal stability. The liner with Nickel-Siliceous coating improves the piston sliding, its resistance to wear and abrasion. 

piston top design

The piston, gravity cast at high silicon content light alloy, reduces thermal expansion and the coupling slack. The piston top design is specific to optimize the compression ratio.

advance technology

The advanced technology and the great performance of the new THOR 250 gives a better feeling when driving making the flight even more performing, dynamic, reactive, beside granting more stability.
