Features

Replace your sprocket without compromise with this JT Sprockets steel sprocket — a part designed for demanding riders. Engineered to fit transmissions with a pitch of 428, this 785 type sprocket features 13 teeth and a sleek black finish that complements most drivetrains. Ideal for lightweight roadsters and the 125 cc models listed in compatibility.

Brand: JT SPROCKETS
Manufacturer Reference: JTF785.13
Material: Steel (high-strength SMC420 alloy)
Number of Teeth: 13
Chain Pitch: 428
Color: Black
Machining: CNC for precise assembly

The SMC420 steel construction combined with CNC machining ensures a consistent geometry, essential for smooth transmission and predictable chain behavior. Its design optimizes the mass/strength ratio to limit unsprung weight while remaining robust against daily stresses.

Compatible with numerous roadsters and small-displacement motorcycles — for example, BENELLI LEONCINO 125 (2024), KEEWAY RKF 125 (2023), or SUZUKI GN 125 (2001) — this JT Sprockets sprocket serves as a reliable replacement part to restore your original gearing or slightly modify engine behavior according to your needs.
