PW50 Aftermarket Minis Billet Quick Turn Throttle Tube to help your rider not have such a long twist of the throttle so they don't have to try to regrip the handlebar to give it full throttle. Our billet throttle tube is cnc'd from aluminum and is much stronger than the OEM Yamaha plastic throttle tube. We gave it the quickest turn possible while still leaving a groove for the cable to ride in keeping it safe. We also gave the gripping surface a knurled finish keeping your grip from spinning on the throttle tube.
