Kit 490cc Ø100mm ATHENA racing for HONDA CRF 450 R 4T 2009 to 2017

Complete kit ATHENA of very high quality high performance! High quality nicasil treated aluminum cylinder, made in italy. Piston Vertex, high compression graphite with segmentation pre-honed steel!

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, of the temperature in the chamber will offer more performance to your machine!

Here, it is not really the maximum power gain that is sought!

Power comes sooner, faster, and a good torque boost is present! This is all that make it a very robust and efficient kit. Mounts with the original cylinder head without modification of the latter.
