CYLINDER WORKS offers an identical cylinder for your 2003, 2004, 2005 and 2006 YAMAHA WRF, YZF 450 4-stroke motocross bike. This Ø95mm aluminum kit features the same characteristics as your original cylinder, but at a lower price than your dealer. This complete engine top 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 about the piston. It's made by VERTEX, one of the world's leading manufacturers of top-of-the-range pistons. The piston head is machined for excellent engine compression. It's also graphitized for better lubrication. As you can see, this kit is a quality cylinder, more powerful than your original kit, and more reliable over the long term. 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 that can be fitted with this kit can be found below. Contractual photo to come.
