This robust replacement kit offers an economical solution to restore the top end after wear or impact. Slight power gain compared to the original model, without modifying the cylinder head which remains unchanged.
This kit allows for the restoration of the combustion chamber without replacing the original cylinder head. Additional parts (rings, bearings, etc.) are available in the NARAKU range if a more comprehensive replacement is needed.

Installation advice: when fitting the rings, ensure the "T" or "J" mark is facing upwards. If the ring stop is not positioned correctly, the piston cannot be fitted.
