Bar End Weights & Caps
About Bar End Weights & Caps
A bar end weight is a heavy plug that fits inside the open end of a handlebar to calm vibration reaching your hands, and a bar end cap or plug simply closes the tube so dirt and water stay out. Riders shop here to add weight to a buzzy bar, to replace a plug that was lost or cracked, or to match the color of the rest of the controls.
Both parts fit inside the bar, so the first thing to check is the inner diameter and wall thickness of your handlebar and whether your grips leave the end open or closed. Weights usually clamp or screw into the bar, while plugs usually push in, and both come in different colors and metals. The samples in this category also include reservoir cap kits for brake and clutch master cylinders, lever perches and a replacement dust cover. Those are listed for specific bikes, mostly dirt bikes, so match the make, model and year in the listing before you order.
Brands here include ZETA, DRC, Renthal, Magura and RFX. If you are changing the bar ends, Grips, Covers & Pads and Handlebars are the nearby parts, and levers are in Hand Brake Levers and Clutch Levers. The whole group is Handlebars, Grips & Controls. For the model-specific parts, pick your machine in the Ride Finder at the top of the page.
FAQs on bar end weights and caps
What does a bar end weight do?
A bar end weight adds mass to the tip of the handlebar. That extra weight can reduce the buzz you feel through the grips on some bikes, though the result varies with the engine and the bar. It also closes the open end of the tube and gives the bar a finished look.
Will a bar end plug fit any handlebar?
No. Plugs and weights fit inside the bar end, so the inner diameter and wall thickness of the bar matter. Read the listing for the size or the model it fits, and measure your bar if you are unsure. Some grips and bar styles also change what will fit.
Why should the end of a handlebar be capped?
An open handlebar tube lets in water and dirt and leaves a bare edge at the end of the bar. A plug or weight closes the tube and gives the end a smooth finish. Choose a plug made for your bar size so it stays in place.
How do I install bar end weights?
Remove the old plug or weight, clean the inside of the bar and fit the new part following the maker's instructions. Many weights clamp or thread in with a bolt, so use the supplied hardware and tighten it as directed. Check it before each ride, since a loose weight can work its way out.
What is a reservoir cap kit?
A reservoir cap kit replaces the cap on a brake or clutch fluid reservoir with a machined or colored version. Listings are made for specific models and master cylinders, so check the bike and year. Keep dirt out of the reservoir while the cap is off and use the fluid type your manual calls for.
