• 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 MOOSE RACING?

When should you replace the cylinder on your YAMAHA WR 450 F?

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.
