Show original supplier description
It utilizes JT Sprockets' C49 high-carbon steel, known for its durability and long wear life. This material, combined with precision manufacturing processes like hobbing, machining, and drilling, ensures exact OEM fit and the closest of tolerances for optimal performance. This rear sprocket features 49 teeth and is designed for use with a 428 chain size. JT Sprockets emphasizes its commitment to using only the finest raw materials and cutting-edge technology. The manufacturing facilities are equipped with high-accuracy machinery, including the latest generation of CNC computer design and computer-controlled metal cutting equipment, to meet the highest quality standards in the motorcycle industry. When considering a sprocket change, JT Sprockets notes that altering the number of teeth can affect acceleration and final speed. Increasing rear sprocket teeth (or decreasing front) leads to more acceleration and shorter gears, often requiring a longer chain. Conversely, decreasing rear sprocket teeth (or increasing front) results in less acceleration, longer gears, and higher final speed, typically maintaining the original chain length. It is recommended to check the number of teeth on your existing sprockets before ordering, and the official JT Sprockets online catalogue can be a helpful resource for verifying part numbers and OEM teeth counts.
