Throttle Tubes
A throttle tube (also called a throttle sleeve) is the part your grip slides onto — the piece that actually turns and pulls the cable. It is one of the first things to wear on a dirt bike or dual-sport: the cam edge rounds off, the tube develops slop against the bar, or it cracks in a tip-over and the throttle starts to stick. A fresh tube is a cheap fix that restores a crisp, snappy throttle.
How to pick the right one:
- Match the bike, not just the bar. Almost every tube fits a standard 7/8" handlebar, but the cable cam and the housing are model-specific. Use the Honda or Yamaha/Kawasaki/Suzuki version listed for your bike, and check the fitment notes on the product page.
- Stock replacement vs. upgrade. The Motion Pro throttle sleeves are direct replacements for the OEM plastic tube. The Motion Pro Titan tubes are the upgrade option for riders who want a more durable tube on a race or trail bike.
- Replace the grip at the same time. Grips are glued and wired on; you will rarely get one off intact. Budget a new set.
- Check the cable and housing too. If the throttle still drags after a new tube, the problem is usually the cable or a bent housing — see Throttle Cables and the complete Throttle Kits (Motion Pro Rev3, Revolver VR and Vortex kits) that include tube, housing and cables together.
