Internal Throttle for 1 " Handlebars - Throttle ONLY

Don't pay $300+ for an internal throttle! This setup has the same features at a fraction of the price. The unique Needle and Ball Bearing Construction creates an extremely smooth operation over competitors internal throttles. Throttle also features a spring-assisted return for added safety.

Internal Throttle


  • This kit uses three types of throttle bearings:
  •       5/32" x 5/16" x 1/8"
  •       3/8" x 7/8" x 9/32"
  •       5/8" x 13/16" x 5/8"
  • Comes with detailed installation instructions.
  • Basic Hand Tools required for proper installation.  (No Welding Required)
  • The throttle side of the cable goes into a barrel in the throttle and is then secured with the provided set-screw.
  • Custom Application for any bike with 1" Handlebars.
  • The internal portion of the throttle slides into the handlebars just short of 2-1/2" (Roughly 2-5/16")
  • NOTE: May not work with dimpled bars. Check for clearance before installation (7-1/4" from the end of the bars).
  • Recommended to be used with Billet Grips, but can also be used with rubber grips with our aluminum throttle sleeve.

(OPTIONAL) Aluminum Throttle Sleeve for Rubber Grips


  • CNC machined from 6061 Aluminum.
  • The throttle sleeve surface is knurled to properly secure your grips.
  • The sleeve also comes with stainless steel set-screws to secure the sleeve to your internal throttle.
  • Works with a 1" Internal Throttle and 1" Rubber Grips.
  • Simply slide the sleeve over the throttle, tighten the set-screws and install your favorite set of rubber grips and you're good to go!

(OPTIONAL) Barnett® Internal Throttle Cable - Black Nylon - 53" Cut-To-Length


  • Works great with our famous internal throttle kit.
  • 53" total length (Cut to length design)
  • Black nylon sleeve keeps your cables safe and working smoothly.

    Great quality, as described

    This internal Throttle assembly was exactly as described. Easy to install with clear instructions (read them twice and they will make more sense once you’ve looked over the whole component). Great build and functionality. The dual guide bearing turning mech is great. Return spring is nice and responsive. I will warn you not to take their measurements to heart. It can change depending on your bars. If I had cut off the full length the recommended I would have been buying new bars. Do your own measuring to make sure it fits. Also, this piece did not fit snug inside my bars. I had to make a spacer because there was a 1/16 gap even after fully tightened. But I have a feeling this is due to my bars, not the throttle because it’s outside diameter was SPOT on with the OD of my bars. still giving a 5 stare because the quality is top notch. Just keep in mind when doing custom work, sometimes changes have to be made on the fly.

    Great quality at an ever better price. I was a little sceptical at first because of how much cheaper it is than all the other throttles on the market, but make no mistake, this was built with care and skill. Great job guys.
