CYLINDER WORKS cylinder for YAMAHA WR 450 F, YFZ 450, YZ 450 F from 2003 to 2013

CYLINDER WORKS offers this cylinder for YAMAHA WR 450 F, YFZ 450, YZ 450 F from 2003 to 2013. The cylinder is the part the piston moves up and down in thousands of times a minute. Its inner wall has a very hard coating that resists wear and holds compression.

Why replace the cylinder?

The benefits:

• Replace a cylinder that is scored, seized or worn beyond its size.
• A new coating holds compression for a long time.
• New piston and new cylinder: the best base for a reliable engine.

Why choose CYLINDER WORKS?

Cylinder Works supplies brand-new, not remanufactured, cylinders with a nickel-silicon-carbide coating; its kits come with a matched forged Vertex piston.

When should you replace the cylinder on your YAMAHA YFZ 450?

A scored or oval cylinder, or one with damaged plating, loses compression and wears the piston quickly. Measure the bore at every top-end rebuild: beyond the wear limit the cylinder must be replaced or resleeved.

Specifications and fitting tips

• Bore: Standard

Cross-Mania tip: Check the diameter of the supplied or required piston and replace the top-end gaskets. A big bore may require carburation or fuel-injection adjustment.
