This kit in Ø100mm against Ø96mm of origin thus makes it possible to pass your motor bike of 450cc has 490cc! A gain of torque and performance will be immediately felt. It allows a gain of 2 NM and 3 HP which is huge on this vehicle. In the original light we have 41.4KW and 56.3 HP but with this cylinder we go to 43.5KW and 59.16HP. Enough to have fun on the tracks or in the forest. ATHENA has moreover foreseen things well because this top engine is sold complete. It includes a case already programmed easy to install, the cylinder, piston, ring and all the seals you need for a quality and tight reassembly. The advantage of taking this engine is that it is studied to be mounted on the original connecting rod with the cylinder head and the original camshaft. So you have no modification to do or adjustment! We propose you herewith the notice as well as the curve of power so that you can see the difference by yourself on the test bench.
