Description

A worn or incorrect rear sprocket directly impacts your TT225 or XT225's power delivery, acceleration response, and chain longevity. The Sunstar 45T sprocket restores optimal gear ratios while its precision engineering ensures reliable performance whether you're tackling trail work or street duty. With 50% increased chain contact area via the exclusive tooth-valley design, you'll experience smoother power transfer and reduced drivetrain stress.

Built by Sunstar—the OEM and aftermarket leader since 1946—this sprocket combines computer-optimized weight reduction with proven durability. The integrated cleaning grooves minimize maintenance intervals, while the lightweight construction maintains strength without unnecessary mass. Installation is straightforward on your Yamaha, making this an essential upgrade for riders who demand reliability and efficiency.
