Description
When your YZ250F’s cylinder shows signs of wear, you’re losing compression, power delivery, and reliability on the track or trail. The Cylinder Works Standard Bore Kit restores your engine to peak performance with factory-matched specifications and Vertex pistons engineered for durability. This is a bolt-on solution that gets you back in the saddle without guesswork or machine shop downtime.
Built to OEM dimensions, the 77mm bore cylinder features nickel silicon carbide plating that resists wear far better than stock, giving you extended service life between rebuilds. The included Vertex pistons are precision-matched to the cylinder for optimal ring sealing and reduced blow-by, translating to stronger, more consistent power. USA manufacturing means you’re getting quality control that aftermarket import alternatives simply can’t match.
