Used motorcycle inspection checklist before you buy

A good used motorcycle inspection checklist covers six areas: paperwork and VIN, frame and body, engine and fluids, drivetrain, brakes, wheels and tires, and a test ride. Work through them in that order, in good light, with the engine cold, and walk away if the title, VIN or frame raises doubts. For any bike you're serious about, also consider having a motorcycle mechanic do a professional inspection.

Used motorcycle inspection checklist: before you go

• Ask for the VIN and check the title status, accident reports and any open recalls
• Ask why the owner is selling, how long they've owned it, and for service records
• Request that the engine be cold when you arrive. A warm engine can hide starting problems
• Bring a flashlight, a small magnet, a rag, a tire pressure gauge, and a friend if possible
• Dress for a test ride, with a helmet and proper gear

NHTSA's recall lookup shows unrepaired safety recalls by VIN, and its VIN decoder confirms what the VIN says the bike is. NMVTIS, the federal title information system, is designed to protect buyers from fraud and unsafe or stolen vehicles, and approved providers sell history reports.

Paperwork and identity

1. Title. Make sure the name on the title matches the seller's ID. Be wary of titles marked salvage, rebuilt or "lost," and of sellers who say they're selling for someone else. A branded title can make a bike harder to insure, register and resell.
2. VIN match. Check the frame VIN against the title, and against the engine number if applicable. Look for signs of tampering.
3. Service records. Regular receipts for oil, tires, chain, brakes and valve service are a good sign. No records isn't an automatic rejection, but it moves the burden of proof to the bike.
4. Recalls. Check with the manufacturer, a dealer or NHTSA for outstanding recalls that should be addressed. Recall repairs are free.

Frame and body

Walk around the bike slowly in good light.

• Frame and welds. Look for cracks, bends, odd welds or fresh paint over a repair
• Swingarm and subframe. Check for straightness and rust
• Fairings and tank. Mismatched paint, new fasteners or stripped screws can mean crash damage
• Handlebars and levers. Scraped or bent ends suggest a drop or a crash
• Footpegs, shifter and exhaust. Scrapes and flat spots can show tip-overs
• Alignment. Stand behind the bike and sight the front and rear wheel to check that they line up

Not all damage is a deal-breaker, but unexplained or hidden damage is a red flag. Cosmetic issues can also be negotiation points.

Engine and fluids

With the engine off:

• Check for oil, coolant or fuel leaks around the engine, head gasket, oil pan, hoses and radiator
• Look at the oil level and color. Milky oil can mean coolant contamination. Metallic glitter can mean internal wear
• On liquid-cooled bikes, check the coolant condition. Rusty or oily coolant is a bad sign
• Inspect the air filter and airbox if accessible

Start the engine from cold:

• It should fire up without excessive cranking and settle into a stable idle
• Listen for ticking, knocking, rattling or grinding
• Look for blue smoke (oil burning), white smoke that doesn't clear (coolant) or black smoke (rich fuel mixture)
• Rev gently. It should respond smoothly, without hesitation or surging

Drivetrain

• Chain and sprockets. Look for hooked teeth, rust, stiff links and excessive slack. A worn set means a repair bill of a few hundred dollars
• Belt or shaft drive. Check for cracks or fraying on belts and oil seepage around shaft-drive housings
• Clutch. The lever should feel smooth, with a clear engagement point
• Transmission. In the test ride, shifts should be positive, with no popping out of gear

Brakes, wheels and tires

These are safety essentials.

Item	What to check	Red flags
Brake pads	Remaining thickness	Worn to the metal, uneven wear
Rotors	Surface condition	Deep grooves, lips, warping, heavy rust
Brake fluid	Color in the reservoir	Dark, dirty or low fluid
Brake hoses	Cracks, bulges	Rubber hoses that look old or swollen
Tires	Tread depth, date code, cracks	Tires older than about five or six years, cupping, flat spots
Wheels	Dents, bends, cracks	Wobble when spun, cracked alloy
Wheel bearings	Play when wiggled	Any side-to-side movement

Check the four-digit date code on each tire. NHTSA notes the last four digits of the tire identification number give the week and year of manufacture, and that manufacturers recommend replacing tires six to 10 years old regardless of tread. Fresh-looking tread on very old rubber still needs replacement. For help decoding it, see how to read a motorcycle tire date code.

Suspension and steering

• Press the front fork down and release. It should rebound smoothly without bouncing
• Look at the fork tubes for oil film, pitting or seal leaks
• Turn the bars lock to lock with the front wheel off the ground if possible. Steering should be smooth with no notchiness or tight spots
• Push and pull on the front wheel to check for play in the steering head bearings
• Press on the rear suspension and check for leaks or unusual noise

Electrical and controls

• Turn the key and verify that the gauges and warning lights come on and then go out
• Test the headlight (high and low beam), taillight, brake light, turn signals and horn
• Check that the battery terminals are clean and connections tight
• Look for messy aftermarket wiring, taped splices or loose connectors, which can cause trouble later
• Operate every switch and the kill switch, and check the sidestand cutoff if the bike has one

The test ride

If the seller allows it and you have proper insurance and a valid license, ride the bike. If they don't allow any ride, think carefully before buying. Pay attention to:

1. Does it track straight with your hands lightly on the bars?
2. Do the brakes stop it evenly, without pulsing, pulling or a soft lever?
3. Does the engine pull strongly and smoothly through the rev range?
4. Is the clutch smooth, with no slipping under load?
5. Any vibration, wobble or odd noises at different speeds?
6. Does the bike run well when fully warm, and does it restart afterward?

Red flags that mean walk away

• Title problems, missing paperwork or a VIN that doesn't match
• Signs of major crash damage or a bent frame
• Milky oil, heavy smoke or serious engine noises
• A seller who refuses an independent inspection
• A price that seems too good, with a story that doesn't add up

Estimating repairs and negotiating

Make a list of what the bike needs now, such as tires, chain, brakes, fluids and battery, and get estimates from a shop. Subtract them from your offer. Costs vary by bike, region and shop, so ask for a written figure rather than guessing. If the bike is older and needs a lot, our framework for deciding if an old motorcycle is worth repairing helps you decide whether the deal still works.

When to see a mechanic

Hire a motorcycle mechanic for a pre-purchase inspection if the bike is expensive, rare, high-mileage or from a private seller you don't know. The fee is small next to the cost of buying a bad bike. Look for shops that offer motorcycle inspections, read how to find a motorcycle mechanic you can trust, or browse motorcycle repair shops in Los Angeles. Never ride a bike that has soft or leaking brakes, a steering wobble, cracked frame parts or fuel leaks, and don't buy one with those problems unless the price reflects a full repair by a professional.
