These latest modifications have of course one and only goal, to further optimize performance at high revs while preserving maximum torque and power at low and mid-range.

Another plus of this high engine was made directly in the design of the cylinder which is seen adding 4 fixing screws for the cylinder head stud. The cylinder is obviously made of aluminum with its specific treatment and Nikasil coating. The cylinder head stud preserves its high compression combustion chamber and is accompanied by the famous blue cylinder head cover cut in the mass.

Its piston is a top-of-the-range mono segment racing model which will reduce friction and consequently increase high speeds. It is equipped with a thin segment in domed ground chrome steel, its 12 X 39mm axle and reinforced clips. Delivered 100% complete, you will have a complete seals pack with different thicknesses of base seals allowing you to fine-tune your settings at the squish level. Have
