Yamaha Motor Co., Ltd. 30X-25448-50-00 Sprocket

The Yamaha 30X-25448-50-00 48T rear driven sprocket is a hardened steel final-drive component that transfers engine power through the chain to the rear wheel, enabling propulsion and speed control on off-road motorcycles. Typically installed on Yamaha XT250L/XT250LC around 1984 models and other similar bikes that rely on a rear-wheel chain drive, this 48-tooth sprocket mounts to the rear wheel hub as part of the chain drive transmission system. It is used for sprocket replacement, drivetrain repair, and restoration of power transmission performance by maintenance teams, motorcycle technicians, and engine rebuilders. The OEM part number is 30X-25448-50-00 and it supersedes 30X-25448-50-33; common replacements include Yamaha 30X-25448-50-33, 5GS-25448-50-00, and 17D-25448-50-00. Applications cover motorcycle drivetrain and power transmission in off-road, trail, and vintage Yamaha models where reliable chain drive performance and the proper gear ratio are essential.
