JT Sprockets Zinc Black Heat-Induction Hardened Rear Sprocket — JTR890.45ZBK (45T)
Product Details

JT's zinc-black plated rear sprocket — same steel core as JT's standard rear, plus a black finish and the heat-induction hardening that holds up better on hard-ridden street bikes.

  • Heat-induction hardened tooth crowns extend service life under aggressive street and trackday use.
  • Zinc-black plating for corrosion resistance and the murdered-out look.
  • CNC-machined to OEM bolt pattern; drops in without modification.
  • Same fitment universe as JT's steel rear in this base number.
  • Built by JT Sprockets in the UK and Thailand.

Intended use: street, sport, trackday.
