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, sport, and adventure bikes.

  • Self-cleaning SCM420 chromoly steel and C49 carbon steel construction, 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 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 OEM gearing across most road, sport, and adventure platforms.

Intended use: street, sport, sport-touring, adventure.
