CYLINDER WORKS offers you its 470cc BIG BORE cylinder for your 2018, 2019 and 2020 YAMAHA WRF, YZF, FX 450 4-stroke motocrosser. This aluminum kit has the same characteristics as your original cylinder, except that you go from Ø97mm 450cc to Ø99mm 468cc without any adaptation or modification to your engine. You'll be able to fit it with your original cylinder head and camshaft. This complete top motor is of the highest quality and finish. The coating is made of silicon carbide nickel to guarantee a minimum friction surface and increase the reliability and life of your cylinder. But it also delivers more torque and performance than the original engine. Let's talk a little about the piston: it's made by VERTEX, one of the world's leading manufacturers of top-of-the-range pistons. The top of the piston is shaped for excellent engine compression. It is also graphitized for better lubrication during passage. We recommend this top-of-the-range cylinder for those who want to give their machine more performance without having to make any modifications. This cylinder is of course sold complete. It includes cylinder, piston, ring, pin, clips and complete gasket pack. You won't need anything else to reassemble this product. A list of vehicles suitable for this kit can be found below. Contractual photo to come.
