Kit 280cc Ø82mm ATHENA racing for HONDA CRF, CRE F, F, X ... 250 4T 2004 to 2015

High performance, high quality ATHENA kit! Aluminum cylinder avaic nicasil treatment of high quality, made in italy. VERTEX forged, high compression piston 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. With this large diameter kit that offers a lot of torque, the ATHENA racing cam shaft is strongly recommended, it saves power at ahut regime (without risk of loss down thanks to the big kit).
