JT Sprockets OE Type Rubber Cushioned Front Sprocket — JTF1345.13RB (13T)
Product Details

JT's rubber-cushioned (RB) front sprocket — same shape as the steel, but with the OE noise-damping inserts that road-bike countershaft assemblies were designed around.

  • Bonded rubber inserts on the carrier face match the OE noise-vibration-harshness spec.
  • C49 high-carbon steel teeth, induction-hardened for service life.
  • CNC-machined to factory profile so your existing chain meshes correctly.
  • JT Sprockets is the world's largest sprocket manufacturer; produced in JT's UK and Thailand facilities.
  • Use when your bike originally shipped with a rubber-cushion front sprocket — most modern Honda, Yamaha, Kawasaki, Suzuki, BMW, Triumph road platforms.

Intended use: street, sport, sport-touring.
