Buying a used motorcycle: what to check at the viewing

Start a used-bike viewing with the seller and the paperwork. Match the frame number to the records, look the bike over cold and watch it start. Only then think about an insured test ride, and only if the bike looks safe. Note faults and anything you couldn't test as you go, so you leave with known costs, open questions and a list of jobs for a mechanic.

This guide covers ordinary used road motorcycles, whether you're buying from a dealer or a private seller on Facebook Marketplace. None of the checks involve taking someone else's bike apart. If it's your first bike, budget for an independent motorcycle mechanic to inspect it.

Before you travel

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

Find the manufacturer's service schedule for that model and year, and mark the expensive jobs, such as a valve-clearance check or belt replacement where it applies. If the seller says they've been done, ask for proof. Stick to questions about this bike; brand rumours won't tell you its service history.

Arrange a daylight viewing with time to look properly, and ask the seller to leave the engine cold. Bring a torch, a tyre gauge, your notes and someone who'll help you think clearly. Ask before you move or operate the bike, take photos or remove the seat. Leave the bolts alone, and don't improvise a way to lift it.

Dealer or private seller?

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

With a private seller, for example on Facebook Marketplace, check who owns the bike and who has the right to sell it. Meet in daylight somewhere you're comfortable, bring a friend and tell someone where you're going. A public meeting place doesn't replace checking the seller and documents, and a friendly chat or an old profile isn't proof of 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 role hasn't been explained. Open payment services yourself instead of following the seller's link. The FTC's online marketplace guidance recommends checking that any protection applies to the item and the seller. Don't assume the platform will refund a vehicle purchase.

Your rights and the transfer rules depend on the country and on whether the seller is a business, so check them locally before signing. Either way, inspect the bike just as carefully: 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 you need to. 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, the 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. Elsewhere, use the equivalent authority. Find out what any extra history report covers, including outstanding finance, theft and recorded damage. A clean result doesn't tell you the mechanical condition, and it won't show every accident.

Read the invoices in date order. Do the dates, mileages and work add up? Ask about gaps or a replaced instrument cluster. A “service” stamp doesn't mean the valve inspection was included. List the next scheduled work, and get 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 and compare both sides. Look for scrapes that line up across the bar ends, levers, mirrors, footrests and engine cases. One replaced lever can have an innocent explanation; several new parts on one side deserve a question and proof of the repair. Check the parts of the frame you can see and the steering stops for cracks, bending or dodgy repairs. ADAC's used-motorcycle guide treats damaged steering stops and frame alterations as serious warning signs.

A straight-looking handlebar is no guarantee of a straight frame. Get suspected structural damage assessed by a specialist. Photograph what worries you and put the decision on hold; you don't need to diagnose it on 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 ask when the tyres were fitted. Michelin advises a yearly professional check after five years of use, and replacement ten years after the tyre's manufacture date, even if it looks fine and has tread left. See Michelin's motorcycle tyre condition guidance.

Get a price for any replacement tyres before you buy. Odd wear on its own isn't evidence of a crash; ask a tyre specialist what's causing it.

Brakes

With the bike securely stationary, apply the brake lever and pedal. Watch for too much travel, a lever or pedal that keeps sinking, or an unexpectedly soft feel. Look for leaks at the hoses and calipers, damaged discs and any pad wear indicators you can see. A lip on a disc doesn't tell you how thick it still is; that needs measuring against the specified limit.

The DVSA motorcycle brake inspection manual separates condition and operation from measured brake performance. At a viewing you're looking for warning signs, not doing a full brake inspection. 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 get a professional inspection.

Steering, forks and suspension

With the engine off and the seller helping to hold the bike, gently turn the bars through their full range. Watch for tight cables, contact with bodywork or steering that catches. Proper bearing checks can mean lifting the front wheel safely off the ground, so 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 forks' 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 isn't necessarily a failed seal, but deep pitting, a substantial leak or unusual movement needs checking. 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 chain, belt or shaft drive. On a chain, look at the links and sprockets you can see for corrosion, stiff links and damaged or hooked teeth, and check the adjustment against the model's manual. Don't spin the wheel with the engine running or put your fingers near a moving sprocket. Ask a workshop to quote for 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, and leave hot coolant caps closed. Ask to look under the seat: loose wiring, bodged connections and badly secured accessories need explaining. Test every light, switch, lock and included accessory, and 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, the normal way. Don't touch the engine or exhaust to check it's cold; ask when it last ran and look at any temperature display. If it's already warm, you haven't seen a cold start; arrange another viewing if that matters to your decision.

Watch how it starts, settles into idle and responds in 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 weather, and some warning lights only clear once the bike moves. Smoke colour or a noise on its own won't give you a reliable diagnosis. Get a mechanic to check the explanation rather than accepting “they all do that”.

Don't keep starting or revving a cold engine to try to expose a fault. ADAC's used-bike and test-ride checklist is a fuller inspection reference. For an electric motorcycle, swap the engine checks for the manufacturer's battery-health, charging, diagnostic and warranty-transfer checks. Never open a traction battery.

Test ride, then check again

Before riding, confirm permission, insurance, licence eligibility and who's responsible for any damage. Bring your own protective gear. If the bike looks unsafe, the seller refuses a ride or the insurance cover is unclear, arrange an independent inspection and suitable transport instead. No test ride leaves a question open; it doesn't make the seller dishonest.

Pick an ordinary route you're comfortable on. Start slowly in a clear area and check that the controls and brakes respond predictably. At sensible, legal speeds, pay attention to the gear changes, clutch, steering, vibration and instruments. Keep both hands on the bars. Hard acceleration, emergency stops and hands-off riding aren't buying tests.

If you notice a wobble, unreliable braking, overheating or anything else worrying, stop safely and contact the seller. After the ride, look for fresh leaks and new warnings without touching hot parts. Write it all down straight away.

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 it to the cost of this bike.
• Unresolved faults: an intermittent warning, a leak, missing service evidence or a questionable repair. Get these inspected before going ahead.
• Reasons to walk away: altered identity markings, unresolved ownership or finance, suspected unsafe structural repairs, or pressure to pay before you can do basic checks.

Compare bikes using purchase price + quoted immediate work + collection and required setup costs. A €4,500 bike needing €700 of confirmed work comes to €5,200 before collection and other costs, so it isn't automatically cheaper than a €5,000 bike with that work documented as done. The figures only show the arithmetic; they aren't repair-price estimates. Leave unresolved faults out of the sum until they've 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 the exclusions and who handles claims. Get a receipt for payment and handover, plus the transfer documents required locally. Sort out insurance and local road-use requirements before riding home, or book transport.

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