Kit 470cc Ø98mm ATHENA racing for HONDA CRF R and RX 450 from 2017 to 2023

Here is a very high quality ATHENA 470cc complete kit to increase the performance of your cross machine!

The cylinder, made in italy, is made of aluminum with a high quality nicasil treatment.

Compression ratio: 13.5:1

The piston is a model from VERTEX, a safe bet ... High compression graphite with a segmentation in pre-ground steel!

The joint pack is an ATHENA (one of the best joint manufacturers in the world), we are clearly on the very high end.

The increase in displacement, compression as well as the reduction of friction will make it possible to obtain an optimal temperature in the combustion chamber and thus offer more performance to your machine!

Here, it is not really the maximum power gain that is sought! The power comes sooner, faster, and therefore a good increase in torque! All these elements put end to end make it a very robust and efficient kit.

This kit is mounted with the original cylinder head without modification of the latter
