Rotax Evo Kart Piston Ring. Ideal for the Rotax Evo line of performance kart engines. Essential component to seal edges of combustion chamber and piston against cylinder wall during operation of engine.
Like most engines, the proper ring gap, fitment, and performance is essential for top performance of your Rotax engine. For non-competition use, you are certainly welcome to exchange the ring yourself. However, NOTE that for Rotax competitions, a certified Rotax service center must be the one to unseal, inspect, and replace your piston ring. If this is not done, your engine will be in non-compliance per technical regulations.
The engine piston ring is part number 215548 (the legal piston ring has this part number stamped directly on the ring).
Each ring is sold separately.
