Kawasaki Chain And Sprocket Kit. Rear Sprocket 48,49,50,51 teeth. This kit includes a Unibear 120 link heavy duty chain constructed with japanese technologoy and supplied with a renthal steel front sprocket and an alloy rear renthal sprocket. Renthal off-road front chainwheels are chosen by more factory motocross and supercross teams than any other chainwheel on the market today. They are CNC machined from a cased hardened and core refined 655M13 nickel chromium steel. Most models utilize mud grooves which are CNC machined into each tooth on both sides to allow mud to flow away from the key contact points between the chain and the chainwheel. This helps reduce wear and increases the drivetrain lifespan. Certain models are available in a computer aided Ultralight design to further reduce weight while still maintaining its structural integrity. UNIBEAR Heavy duty 520 chains are specifically made for motocross and off road riding, offering fantastic performance at an excellent price.

Renthal UltralightT rear chainwheels are manufactured to extremely tight tolerances from 7075 T6 aluminium alloy which is 66% lighter than steel, yet incredibly durable. Their advanced tooth profile, concentricity and accuracy of fit provide maximum power transfer and long-life. Renthal's combination of a high strength base material and exceptionally hardwearing surface result in significantly increased chainwheel life over other brands. If you have any questions.
