Fits: Yamaha YZF-R1 04-05. 520 steel conversion kit contains: 16 tooth chromoly front sprocket; 45 tooth steel rear sprocket; and RK 520GXW-116 link chain. Sealed XW-ring chain features heat treated high carbon alloy steel components with seamless rollers and shouldered bushings providing the user with a 50 percent longer wear life than basic O-ring chains. XW-ring uses an advanced nitrile butadiene composite and features three contact lips and two convex outer stabilizers; this means three lubrication pools to protect against high speed abrasion, extreme heat build up, torsional flex and loss of lubricant. XW-ring chains are the best high-speed, extreme heat performance chains available today and include a clip type master link.
