HONDA TRX 450ER/ATV (2006-2011) Top End CP CARRILLO piston kit

This reduces friction and leads to even higher heat resistance. The internal bracing minimizes piston deformation in order to achieve maximum ring support and deliver more force. The additional oil can lubricate the piston pin through the inner windows.These windows together with the CP standard `` Double - Pin - Oiler '' promote a longer life and more usable horsepower. The inner bracing additionally strengthens the part in the most critical area of ​​the bolt hole. It maximizes the durability by reducing the friction in the piston pin bore. The cylinder must be honed with special diamond honing stones. The cylinder honing is necessary with regard to the correct running clearance and the surface roughness corresponding to the piston ring.
For years of construction 2006 to 2009.
