JT Sprockets 420 Steel Front Sprocket, 14T (JTF1042.14)

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.
