How to Change Throttle Grips on a Motorcycle

Replace a notchy-feeling throttle grip using only a few tools.

While a sticky-feeling throttle can often be attributed to an improperly lubricated cable, the throttle twist grip can also create problems as wear begins to take its toll. This wear generally presents itself as a notchy feeling as the grip is twisted, usually created by a rough spot on the inside of the tube-like throttle grip. Replacing the throttle grip can restore the smooth operation of your motorcycle's throttle.

Things You'll Need

• Wrench
• Phillips screwdriver
• Throttle grip

Instructions

1. Use a wrench to loosen the throttle cable adjusters' lock nuts on the bottom of the right handlebar's throttle assembly. Twist the cable adjusters clockwise to loosen the throttle cables.

2. Remove the pair of screws from the bottom of the throttle assembly using a Phillips screwdriver. Separate the upper and lower portions of the throttle assembly to access the throttle grip and cables.

3. Pull the ends of the throttle cables out of the detents on the end of the throttle grip. Slide the throttle grip from the handlebar.

4. Slide a new throttle grip onto the handlebar. Insert the ends of the throttle cables into the throttle grip's detents.

5. Place the upper and lower portions of the throttle assembly over the throttle grip. Tighten the assembly's screws with a Phillips screwdriver.

6. Turn the throttle cable adjusters counterclockwise to tighten the cable. Tighten the adjusters' lock nuts with a wrench.

Tips & Warnings

• Ideally, the throttle grip should provide one-eighth of an inch of movement before the throttle cables are pulled. Twist the throttle grip occasionally while tightening the throttle cables to check the cable tension.
