JT Sprockets Steel Front Sprocket — JTF284.15 (15T)
Product Details

A direct-fit C49 high-carbon steel front sprocket from the world's largest sprocket maker — the standard for stock replacement on modern street and sport bikes.

  • Self-cleaning SCM420 chromoly steel (and C49 carbon steel on most road parts), induction-hardened on the tooth profile for a hard wear surface over a tough core.
  • CNC-machined to OEM tooth profile so your existing chain runs without re-meshing issues.
  • Available with rubber-cushion (RB) damping inserts on select fitments — same noise/vibration spec as the OE part.
  • JT Sprockets is the world's largest sprocket manufacturer; produced in JT's UK and Thailand facilities to ISO-grade QC.
  • Sized for 520 pitch with tooth counts spanning the most common street and sport gearing.
