Here is a complete ATHENA 490cc kit of very high quality to increase the performanes of your cross machine!
The cylinder, made in Italy, is made of aluminum with a high quality nicasil treatment.
Compression ratio: 11.6: 1
The piston is a VERTEX model, a safe bet ... High compression graphity with pre-ground steel segmentation!
The joint pack is an ATHENA (one of the best manufacturer of joints in the world), we are clearly on the very top of the range.
The increase in displacement and 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 assembled with the original cylinder head without modification of the latter.
