Kit 480cc ATHENA Ø100mm, aluminum cylinder / piston for QUAD HONDA TRX 450 R from 2006 to 2014

High performance, high quality ATHENA kit! Aluminum cylinder avaic nicasil treatment of high quality, made in italy. Piston VERTEX, high-compression graphite with pre-ground steel segmentation! Joint ATHENA (one of the best joint manufacturer in the world), we are clearly on the very high end. The increase in displacement, compression as well as the reduction of friction, from the temperature to the room will offer more performance to your machine! Here, it is not really the maximum power gain that is sought! The power comes earlier, faster, and a good increase in torque is present! That's what makes it a very robust and powerful kit. Mounts with the original cylinder head without modification of the cylinder head. The expected gain is about 5cv and a little more even with the engine torque!
