Your engine has tightened and you want to start again on a quality engine so you don't have to dismantle it soon ? Then here is the complete engine top proposed by ATHENA to reassemble your YAMAHA YZ 125cc 2 stroke from 2005 to 2017. This kit is sold complete as on the picture with its axle, clips, ring, piston, gasket, cylinder head, screws and its cylinder. This kit is not a big bore, it has the same characteristics as the original one so it is Ø54mm which gives us 125cc. This kit will allow you to refurbish your machine and especially to have a quality cylinder as reliable as the original. This kit is still more powerful than the original Yamaha kit. It allows a gain of 2hp. Your motorcycle will go from 32.4 hp to 34 hp thanks to the high engine ATHENA. Here is the power curve so that you can see by yourself the difference between the original and the kit ATHENA. It is of course of excellent quality as usual at ATHENA. The nikasil is really of excellent manufacture to guarantee you an increased reliability. We also have all the gaskets, rings and all the spare piston dimensions so that you can keep your cylinder as long as possible. Below you will find a list of vehicles that are compatible with this kit.
