      A top of the range kit that will allow you to start over and increase the displacement and therefore the performance of your machine.

      Here is the big bore kit proposed by ATHENA to increase the displacement of your motocross / enduro YAMAHA YZF 250cc 4 stroke from 2001 to 2007 / YAMAHA WR-F 250cc 4 stroke from 2001 to 2012 . GAS GAS ECF 250cc. This kit in Ø83mm against Ø78mm of origin thus allows to pass your motor bike of 250cc has 290cc! A gain of torque and performance will be immediately felt. It allows a gain of 3 HP on average which is huge on this vehicle. Enough to have fun on the tracks or in the forest. ATHENA has also planned things well because this top engine is sold complete. It includes the cylinder, piston, ring as well as all the gaskets you need for a quality and tight reassembly. The advantage of taking this engine is that it is designed to be mounted on the original connecting rod with the original cylinder head and camshaft. So you don't have any modification to do ! Here attached the power curve so that you can see by yourself the difference between the original and the big bore. You will also find a detailed list of vehicles on which this cylinder can be mounted.
