NEW & IMPROVED LA County Choprods Internal Throttle is here! LACC vastly improved the design by lengthening the New Aluminum Outer Sleeve and closing the inner end of the Travel Grooves, making it easier to secure your grip without the chance of binding. Additionally, they added another double ball bearing and pin assembly to enhance the balance and performance. Lastly, the outer sleeve and slide plunger are hard anodized for smoother operation and longer life. All of the aluminum parts are CNC machined from aircraft quality materials and are coated for corrosion prevention, clear anodizing for the remaining aluminum parts and black oxide for the steel inner throttle tube. This unit is made entirely in the USA!!!!! Fits most 1? handlebars. For ease of installation and adjustment, we recommend the use of LACC Universal Throttle Cable or any similar cable.
