Product Details

JT's self-cleaning (SC) rear sprocket — mud-shedding profile for off-road and dual-sport bikes that ride through clay, sand, and wet trail.

  • Self-cleaning tooth profile pushes mud, sand, and debris out of the tooth gullets before it builds up.
  • C49 high-carbon steel with induction-hardened tooth crowns for off-road wear life.
  • CNC-machined to OEM bolt pattern; drops in to factory MX, enduro, and dual-sport applications.
  • Same fitment universe as JT's steel rear in this base number.
  • Built by JT Sprockets in the UK and Thailand.

Intended use: off-road, MX, enduro, dual-sport.
