Description

A 12-tooth countershaft sprocket directly impacts your KTM's acceleration curve and throttle response—smaller tooth counts deliver quicker engagement off the line at the cost of top-end RPM. If you're running stock gearing and feeling bogged down in tight technical sections or need faster spool-up for race conditions, this JT sprocket delivers the geometry change you're after. Built from SCM420 chromoly steel, it offers the durability to handle repeated shifts and high-load acceleration without tooth stripping or premature wear.

  • SCM420 chromoly steel
  • 12-tooth configuration
  • CNC-precision engineered
  • Lightweight design
  • Bolt-on installation
  • KTM specific fitment
  • Enhanced acceleration response
  • Improved throttle engagement
  • Long-term durability
  • MPN: JTF1903.12

Helps keep cool, works great!
