As every Harley Davidson XR1200 or Sportster owner knows, the throttle pull is VERY long.
This requires you to regrip or "roll" the throttle from your palm to your fingers to reach full throttle.
That's why we implemented our patent pending variable ratio cam to decrease overall pull. Now you can easily turn the throttle from cruise speed to WFO without jeapordizing your grip.
This will work on all Harley Davidson with stock THROTTLE CABLES actuated throttles from 1996-2012
No extra parts needed. Fits on original XR1200 throttle cables, direct repalcement part
