Motorcycle maintenance checklist
This is the same list we run in the shop, written so you can run it in your own garage. Print it, tape it inside the toolbox door, and work top to bottom. Nothing here needs special tools beyond a tire gauge, a torque wrench, and a rag. Your owner's manual has the exact specs for your bike — where it disagrees with this page, the manual wins.
Tip: print this page straight from your browser — it lays out as a one-page checklist.
Every ride — 2 minutes
The old T-CLOCS walkaround, trimmed to what actually strands people. Do it in the driveway before the helmet goes on.
- Tire pressure, cold, with your own gauge — front and rear specs differ and both are on the swingarm or chain-guard decal.
- Tread depth and sidewalls: wear bars flush with the tread means done; cracking or weather-checking means done regardless of tread.
- Chain or belt: correct slack, no tight spots, no missing teeth or frayed edges. Chain should look oiled, not dripping or dry-rusty.
- Brakes: both levers firm, not spongy. Pads with less than about 2 mm of friction material left get replaced now, not later.
- Lights and horn: headlight high and low, brake light on both front and rear inputs, turn signals, horn.
- Leaks: look under the bike where it sat. Fresh oil, coolant, or fork oil on the ground is a stop-and-fix.
- Fluid sight glass or dipstick reading inside the marks, bike level and upright.
- Controls and cables move freely and snap back; nothing binds at full lock.
Monthly — or every tank of fuel if you ride hard
Ten minutes with the bike on a stand catches the slow failures before they get expensive.
- Clean and lube the chain after every 400–600 miles or any wet ride; adjust slack to the manual's spec, measured at the tightest point.
- Check the battery: over 12.6 V rested is healthy, under 12.4 V means it's on the way out. Keep a smart tender on it when the bike sits.
- Wipe fork tubes; any oil film above the seal means the seal is leaking and the fork is due for service.
- Look at brake and clutch fluid level and color. Clear-amber is good, dark coffee means it's absorbed water and needs flushing.
- Coolant level at the overflow tank between the marks (liquid-cooled bikes only, engine cold).
- Air filter check — dusty riding kills filters faster than mileage does.
- Torque the obvious: axle nuts, pinch bolts, caliper bolts, exhaust hardware, license-plate and mirror fasteners.
- Spin both wheels and listen for wheel-bearing rumble or a dragging brake pad.
By mileage — the money items
Intervals vary by bike, so the manual always wins. These are the ballparks we see hold up in the shop.
- Engine oil and filter: every 3,000–5,000 miles on most bikes, sooner for hot, short, or dusty riding.
- Harley Big Twins: three separate oils — engine (about 5,000 mi), primary chaincase (about 10,000 mi), transmission (about 20,000 mi). They are not interchangeable fluids.
- Air filter: clean or replace every 10,000–12,000 miles, more often on gravel and dirt.
- Spark plugs: 10,000–20,000 miles depending on plug type; gap the new ones before they go in.
- Brake fluid: flush every two years even if it looks fine — it pulls moisture out of the air.
- Coolant: replace every two to three years on liquid-cooled bikes.
- Fork oil: 15,000–20,000 miles, or any time the front end starts diving and packing over bumps.
- Valve clearance check: at the manufacturer's interval. Ignoring it burns valves, and that repair is not a checklist item.
- Tires: replace at the wear bars or by age at roughly five to six years, whichever comes first.
Seasonal storage — before it sits
Most spring no-starts are November's fault. Twenty minutes now is a dealership bill avoided.
- Fill the tank and add fuel stabilizer, then run the engine a few minutes so treated fuel reaches the carb or injectors.
- Change the oil before storage, not after — used oil is acidic and eats bearings while the bike sleeps.
- Put the battery on a smart maintainer, or pull the negative lead entirely if there is no outlet.
- Set tires to full pressure and get the weight off them if you can; flat-spotting is real.
- Wash and wax, then leave it dry. Trapped road salt corrodes fasteners all winter.
- Cover it in a breathable cover, indoors if possible. Damp-cold cycles do more damage than pure cold.
Stop riding, call the shop
A checklist keeps a healthy bike healthy. These are not checklist items — they are trailer-it-in items.
- Spongy brake lever or a pedal that goes to the floor.
- Any knock, tick, or metallic rattle that changes with engine speed.
- Coolant or oil on the exhaust, or steam and sweet smell at idle.
- Fork oil on the tube, wobble in the front end, or a wheel-bearing rumble.
- Charging problems — headlight dimming at idle, repeated dead batteries.
- Valve-clearance intervals you have never had done.
