Kit 280cc Ø82mm ATHENA racing for HONDA CRF R 250 4T 2010 to 2017

Complete kit ATHENA of very high quality high performance! High quality nicasil treated aluminum cylinder, made in italy. VERTEX forged piston, high compression 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, 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.

With this large diameter kit which offers a lot of torque, the ATHENA racing camshaft is strongly recommended, it saves power at high speed (without risk of loss at the bottom thanks to the large kit).
