Since we rode dirt bikes long before we ever got freedom machines, the cheap plastic throttle tubes have always been a let down. These are way more accurate and with an aluminum sleeve, you can change out rubber grips as often as you like. Also, note different size ferrules to match up with a variety of cables. We sell just the tube separately too, just in case you want to use your stock HD control pods. We'll have a full how-to and other info up on the site next week, but didn't want to keep folks waiting so we've added them to the store.
Right now we've only got two-cable style in stock, but will be doing a single cable version down the road. You can use this one with a single cable and just cap one hole with a short bolt. Also, the 7/8" grips slip over this metal sleeve and your 1" left-side bar pretty easily if you put a little spray mount, hair spray or other adhesive on there to lube it up. (Yes, we're still lame and out of proper 1" Kung Fu's)
