Sprocket - Drive - Rear - 428 - JTR798 Series - 51 Tooth - YZ85LW

JT Sprockets are computer designed to achieve ultimate strength while retaining as little weight as possible. Made from high carbon steel they meet or exceed all possible industry standards and have indeed become an industry standard in themselves. Remember to always replace sprockets and chain as a set. Running a new sprocket or chain in an otherwise worn out system will only cause premature wear and further expense and headache.
