Buying a used motorcycle: what to check at the viewing

Start a used-bike viewing with the seller and paperwork. Match the frame number to the records, inspect the bike cold and watch it start. Then consider an insured test ride, only if the bike appears safe. Write down faults and anything you couldn't test as you go. You'll leave with known costs, unanswered questions and a list of things that need a mechanic.

This guide covers ordinary used road motorcycles, whether you're buying from a dealer or a private Facebook Marketplace seller. You can make these checks without taking someone else's bike apart. If it's your first purchase, booking an independent motorcycle mechanic to inspect it is a sensible part of the budget.

Before you travel

Save the advert and ask for the exact model, year, mileage, registration and service history. Ask plainly: “What needs fixing?”, “Has it been dropped or crashed?”, “How long has it been standing?” and “What has been changed from standard?” An honest answer about a fault is more useful than “rides perfectly”.

Find the manufacturer's service schedule for that model and year. Mark the expensive jobs, such as a valve-clearance inspection or belt replacement where applicable. If the seller says they've been done, ask for evidence. Make a shortlist of questions about this particular bike; a rumour about an entire brand won't tell you its service history.

Arrange a daylight viewing with enough time to look without rushing. Ask the seller to leave the engine cold. Bring a torch, a tyre gauge, notes and someone who can help you think clearly. Ask permission before moving or operating the bike, taking photos or removing the seat. Leave the bolts alone, and don't improvise a way to lift it.

What changes at a dealer or a private viewing?

At a dealer, ask what preparation the advertised price includes. Get the inspection record, service invoice, list of faults to be fixed before collection and written warranty terms. If the advert says “fully checked”, ask what was measured, what was replaced and what's still due. If the dealer is selling for someone else, confirm who your contract will be with.

With a Facebook Marketplace seller, check who owns the bike and who has the right to sell it. Meet in daylight somewhere you're comfortable with, bring a companion and tell someone where you're going. At a public meeting place, check the seller and documents just as carefully. A friendly chat or an old profile doesn't prove ownership.

Don't send money because another buyer is supposedly on the way. Be wary of delivery-only stories, unexpected escrow links, requests for login codes or payment to someone whose involvement hasn't been explained. Open payment services yourself rather than following the seller's link. The FTC's online marketplace guidance recommends checking which protections apply to the item and seller. Don't assume the platform will reimburse a vehicle purchase.

Your rights as a buyer and the transfer requirements depend on the country and whether the seller is a business. Check those locally before signing. Inspect the bike just as carefully in either setting: showroom lighting and a tidy garage tell you little about the brakes.

Check the frame number and records

Find the VIN, or frame number, using the manual if needed. Compare the stamped number with the original registration documents character by character. A sticker alone isn't enough. Stop if the numbers don't match, markings are damaged or you still don't know whether the seller has the right to sell.

For a UK purchase, GOV.UK's used-vehicle checks cover identity, documents, test history and recalls. In the Netherlands, start with the RDW's purchase guidance and official registration check. Use the equivalent authority elsewhere. Find out what any extra history report covers, including outstanding finance, theft and recorded damage. A clean result doesn't establish the bike's mechanical condition or show every accident.

Read the invoices in date order. Do the dates, mileages and work make sense together? Ask about gaps or a replaced instrument cluster. A “service” stamp doesn't prove that a valve inspection was included. List the next scheduled work, and ask a workshop to check it if the paperwork is vague.

Work your way around the bike

Bodywork, frame and signs of a fall

Stand back, then compare both sides. Look for scrapes that line up across the bar ends, levers, mirrors, footrests and engine cases. A replaced lever can have an innocent explanation; several new parts on one side are worth asking about, along with evidence of the repairs. Look at the frame areas you can see and the steering stops for cracks, bending or suspicious repairs. ADAC's used-motorcycle guide highlights damaged steering stops and frame alterations as serious concerns.

A straight-looking handlebar doesn't prove the frame is straight. Get suspected structural damage assessed by a specialist. With permission, photograph what concerns you and put the decision on hold; you don't need to diagnose it in the driveway.

Tyres and wheels

Look over the full tread, both sidewalls and the visible rims. Ask the seller to move and secure the bike so you can see the hidden section. Note cracks, bulges, anything stuck in the tyre and uneven wear. Read the date marking and check the manufacturer's advice on tyre age and condition. An old tyre can still need replacing even with deep tread. See Michelin's motorcycle tyre condition guidance.

Get a price for any replacement tyres before buying. An unusual wear pattern doesn't by itself prove a crash; ask a tyre specialist to assess the cause.

Brakes

With the bike securely stationary, apply the brake lever and pedal. Notice excessive movement, a lever or pedal that keeps sinking, or an unexpectedly soft feel. Look for leaks at hoses and calipers, damaged discs and pad wear indicators you can see. A lip on a disc doesn't tell you its remaining thickness; that needs measuring against the specified limit.

The DVSA motorcycle brake inspection manual separates condition, operation and measured performance. A viewing lets you look for warning signs; a full brake inspection needs more than that. A current inspection certificate doesn't tell you how the bike behaves today. If you have doubts about the brakes, skip the test ride and arrange a professional inspection.

Steering, forks and suspension

With the engine off and the seller helping support the bike, gently turn the bars through their range. Watch for tight cables, contact with bodywork or steering that catches. Proper bearing checks can need the front wheel safely lifted clear of the ground; leave those to a mechanic. The DVSA steering inspection guidance covers roughness, restricted movement and excess bearing play.

Look for damage or pitting on the fork sliding surfaces and oil around the seals. If the seller can safely show the suspension moving, watch for sticking or fresh leaks. A thin film of oil doesn't by itself prove a seal has failed. Deep pitting, a substantial leak or unusual movement needs assessment. The DVSA suspension inspection guidance explains the technical checks; bouncing the bike a few times won't cover them.

Final drive, fluids and electrics

Check whether the bike has a chain, belt or shaft drive. On a chain-driven bike, look at visible links and sprockets for corrosion, stiff links and damaged or hooked teeth. Check the adjustment using the model's manual. Don't spin the wheel with the engine running or put fingers near a moving sprocket. Ask a workshop for a quote covering the whole job, including any related worn parts.

Look for leaks around the engine and hoses, and under the bike. Check fluid levels with the bike in the position and at the temperature the manual specifies. Leave hot coolant caps closed. Ask to look under the seat: loose wiring, makeshift connections and accessories that aren't properly secured need explaining. Test each light, switch, lock and included accessory, plus the horn. Honda's owner maintenance guidance recommends leaving mechanical maintenance to trained technicians.

Watch a cold start

Let the seller start the bike outdoors, using its normal procedure. Don't touch the engine or exhaust to find out whether it's cold. Ask when it last ran and check any available temperature display. If it's already warm, note that you haven't seen a cold start and arrange another viewing if that matters to your decision.

Watch how it starts, settles into idle and responds during normal use. Note repeated attempts to start, persistent smoke, knocking, leaks or warning lights that don't behave as the manual describes. Brief condensation vapour can appear in cold conditions, and some warning lights only clear after the bike moves. Smoke colour or a noise alone won't give you a reliable diagnosis. Have a mechanic check the explanation rather than accepting “they all do that”.

Don't repeatedly start or rev a cold engine to try to expose a fault. ADAC's used-bike and test-ride checklist gives a fuller inspection reference. For an electric motorcycle, use the manufacturer's battery-health, charging, diagnostic and warranty-transfer checks in place of combustion-engine checks. Never open a traction battery.

Test ride, then check again

Before riding, confirm permission, insurance, licence eligibility and who is responsible for damage. Bring your own protective gear. If the bike looks unsafe, the seller refuses a ride or insurance cover is unclear, arrange an independent inspection and suitable transport instead. An unavailable test ride leaves a question open; it doesn't prove the seller is dishonest.

Choose an ordinary route you're comfortable riding. Start at low speed in a clear area, checking that the controls and brakes respond predictably. At sensible, lawful speeds, pay attention to gear changes, the clutch, steering, vibration and instruments. Keep both hands on the bars. Don't use hard acceleration, emergency braking or hands-off riding as buying tests.

If you notice wobble, unreliable braking, overheating or another worrying symptom, stop safely and contact the seller. After the ride, look for fresh leaks and new warnings without touching hot parts. Write down what you noticed straight away, including anything you couldn't assess.

Negotiate, get help or walk away

Sort your notes into three groups:

• Known wear: tyres or scheduled work where you know what's needed and have a workshop quote. Add that to the cost of this bike.
• Unresolved faults: an intermittent warning, leak, missing service evidence or questionable repair. Get further inspection before going ahead.
• Reasons to leave: altered identity markings, unresolved ownership or finance, suspected unsafe structural repairs, or pressure to pay before you can make basic checks.

Compare bikes using purchase price + quoted immediate work + collection and required setup costs. For example, a €4,500 bike needing €700 of confirmed work comes to €5,200 before collection and other costs. It isn't automatically cheaper than a €5,000 bike with that work documented as complete. These figures just show the arithmetic; they aren't repair-price estimates. Leave an unresolved fault out of the calculation until it's been diagnosed and quoted.

Get a written offer listing the bike, price, mileage, disclosed faults, included keys and accessories, and any work promised before collection. If there's a warranty, check its exclusions and who handles claims. Get a receipt for payment and handover, along with the transfer documents required locally. Arrange insurance and meet local road-use requirements before riding home, or book transport.

“I need more information” and “this one isn't for me” are useful outcomes too. Keep the completed list and your separate notes to compare bikes, then reset before the next motorcycle so the last viewing's ticks don't carry over. Once you have a bike, use the everyday pre-ride checklist and, after a lay-up, the pre-season check.
