Your engine is tight and you'd like to start again with a quality engine so you don't have to dismantle it any time soon? Then here's the complete engine top proposed by ATHENA to rebuild your YAMAHA YZF 250cc and YAMAHA WRF 250cc. This kit is sold complete as shown in the photo, with axle, clips, ring, piston, gasket and cylinder. This kit is not a big bore, it has the same characteristics as the original, so it is Ø77mm which gives us 250cc. This kit will enable you to refurbish your machine and, above all, have a quality cylinder as reliable as the original. Enclosed is the power curve so you can see for yourself the difference between the original and the ATHENA kit. It is of course of excellent quality, as usual at ATHENA. The nikasil is truly of excellent manufacture to guarantee you increased reliability. We also have all the seals, rings and piston dimensions you need to keep your cylinder as long as possible. Below, you'll find a list of vehicles compatible with this kit.
