The Italkit Alu Racing offers some very nice new features compared to its older predecessor. First of all, the now three-part outlet catches the eye, which allows a considerably larger outlet area. In combination with the new, now coated piston, it is now a serious midrace cylinder that can play in the same league as a Stage6 Sport Pro.

The high quality cast aluminium cylinder with its very resistant coating of wear-resistant Nikasil and a modular cylinder head offer the best conditions for this power to be permanently scooped onto the rear wheel.
Conclusion: Best conditions for a very powerful but still roadworthy Midrace engine!
