Collection: Cylinder Works Canada - Authorized Dealer - My Parts Guy

Cylinder Works produces replacement and big bore cylinder kits for four-stroke and two-stroke dirt bikes and ATVs. Standard bore cylinders return a worn engine to factory specification, while big bore kits add displacement and arrive matched with pistons, rings and gaskets. Coverage includes Honda CRF, Yamaha YZ and Kawasaki KX models along with popular sport ATV engines such as the TRX 450R. Cylinders use a hard plated bore rather than a pressed-in steel sleeve, so heat transfer and wear resistance stay closer to original. My Parts Guy ships Cylinder Works across Canada in CAD.
