The brand new Polini THOR 250 features a liquid cooling system, that grants an extraordinary steady power output and better performance at every rpm.
The brand new Polini THOR 250 features a liquid cooling system, that grants an extraordinary steady power output and better performance at every rpm.
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. 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. 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.
It's equipped of big wheels and front fork with shock absorber.
