DUZFOREI T8F 54T Rear Sprocket + 116-Link Chain for 47cc/49cc 2-Stroke Pocket Bikes

Upgrade your ride with the DUZFOREI T8F 54T Rear Sprocket Kit

This compact drivetrain upgrade is designed for 47cc and 49cc two-stroke engines commonly found on Chinese kids pocket bikes, ATVs, pit bikes, quads, and dirt bikes. The kit pairs a 54-tooth rear sprocket with a 116-link chain and five master links to form a complete install that is ready for action. The folded chain length is 360mm, which helps keep routing neat in tight frames while maintaining reliable tension during throttle and shift. The sprocket’s specifications include an inner diameter of 55mm, a minimum mounting hole diameter of 6mm, a sprocket diameter of 140mm, and a center-to-center spacing of 65mm. A compatibility note is essential: the T8F chain works only with T8F 25H sprockets, so please verify your bike’s sprocket type before upgrading to ensure smooth operation and avoid misalignment.
