Motorcycle Chain Cleaning: Prevent Wear and Keep Shifting Smooth
A dirty, grimy motorcycle chain doesn’t just look bad—it also causes premature wear to the chain, sprockets, and engine components, and can lead to rough shifting or even chain failure. Cleaning your chain regularly is a simple task that takes 15–20 minutes, but it can save you money on repairs and keep your bike running smoothly. Here’s how to do it properly.
First, gather your supplies. You’ll need: a chain cleaner tool (optional but makes the job easier), a stiff-bristle brush (like a parts-cleaning brush or an old toothbrush), a biodegradable degreaser (avoid harsh chemicals that can damage the chain’s O-rings or X-rings), a clean rag, and a bucket of soapy water (for cleaning your hands afterward). You may also want to wear gloves to protect your hands from grease.
Prepare the bike. Park your motorcycle on a level surface and put it on a stand (to lift the rear wheel off the ground—this lets you spin the chain freely). If you don’t have a stand, ask a friend to hold the bike steady while you work. Shift the chain to the middle gear (this keeps tension on the chain, making it easier to clean). Cover the rear tire and any nearby bodywork with a plastic sheet or old towel—this prevents degreaser from damaging the tire or paint.
Remove loose dirt first. Use the stiff brush to scrub the chain gently, removing any loose dirt, mud, or debris. Pay extra attention to the gaps between the chain links (where grime builds up most). Spin the rear wheel slowly as you brush—this lets you clean the entire length of the chain.
Apply degreaser and scrub. Spray the degreaser evenly over the chain, making sure to coat all links (including the inner plates where the chain pivots). Let the degreaser sit for 5–10 minutes—this breaks down the old grease and grime. Use the brush to scrub the chain again, focusing on the links and sprockets. If you have a chain cleaner tool, attach it to the chain (following the tool’s instructions) and spin the rear wheel— the tool’s brushes will clean the chain as it moves.
Rinse and dry the chain. Use a garden hose with low pressure to rinse off the degreaser and grime—avoid high pressure, which can force water into the chain’s bearings (causing rust). Make sure to rinse all parts of the chain, including the sprockets. Once clean, use a dry rag to wipe the chain thoroughly—any leftover moisture can cause rust. Spin the rear wheel as you wipe to dry the entire chain.
Inspect the chain for wear. While the chain is clean, check for signs of damage: look for loose links, rust spots, or stretched links (to check for stretch, measure 20 links—if the distance is more than 31.8 inches, the chain is stretched and needs to be replaced). Also, check the sprockets—if the teeth are worn down (pointed or uneven), they should be replaced along with the chain (a new chain on worn sprockets will wear out quickly).
Lubricate the chain (after cleaning). Once the chain is completely dry, apply motorcycle-specific chain lubricant (avoid using motor oil, which is too thin and washes off easily). Apply the lube to the inner plates of the chain (where the links pivot) while spinning the rear wheel. Let the lube sit for 10–15 minutes to soak in, then wipe off any excess with a rag—too much lube attracts dirt.
Clean your chain every 300–500 miles (or more often if you ride in mud, rain, or dusty conditions). Regular cleaning keeps your chain in top shape and extends its life.
