Questions to Ask When Buying a Motorcycle
For anyone looking at a used motorcycle from a private seller or a dealer. These 20 questions cover title and VIN, crash and track history, service records, tires and drivetrain, leaks and modifications, storage, and how to arrange a cold start, an inspection and a test ride.
The questions
Open any question for the note
How long have you owned it, and are you the person who has been riding it?
Why ask it
A seller flipping a bike they bought two months ago knows nothing about how it was treated and has an incentive not to look too closely. Ask who rode it and how, because a bike commuted year round in a wet climate wears differently than one ridden on dry weekends.
Why are you selling it?
Why ask it
Moving up a class, a new baby, or a garage that only fits one bike are answers you can sanity check against the rest of the conversation. Watch for the seller who describes a problem in passing and then reframes it as a preference.
Is the title in your name, and is it free of any lien?
Why ask it
A bike being sold by someone whose name is not on the title, or with a loan still recorded against it, can leave you with a machine you cannot register. Ask to see the physical title next to the seller's photo identification before any money changes hands.
Does the VIN on the frame match the title and the registration?
Why ask it
Check it yourself rather than accepting a photograph, since mismatched or tampered numbers point to a stolen or rebuilt machine. While you are looking, check whether the title is branded salvage, rebuilt or flood, because that follows the bike forever and cuts its resale value.
What is the mileage, and how many of those miles are yours?
Why ask it
Very low mileage on an older bike is not automatically good news: seals dry out, fuel goes stale and brake fluid absorbs water whether the bike moves or not. What you want is steady use with maintenance, not a machine that sat for six years in a shed.
Has it ever been dropped, crashed, or laid down, even in a parking lot?
Why ask it
Almost every used bike has touched the ground once, so a flat denial invites you to go looking. Check bar ends, lever tips, mirror stalks, exhaust cans, engine case edges and frame sliders for scuffs, then ask again about whichever one you found.
Has it ever been ridden on a track?
Why ask it
Track use is not disqualifying and track bikes are often better maintained, but it means sustained high revs and hard braking that no odometer reading conveys. Look for safety wire on drain bolts, missing mirrors, taped lights and a lap timer mount as signs the answer should have been yes.
Do you have service records, and what was done at the last service?
Why ask it
Receipts turn claims into facts, and their absence on a bike with real maintenance needs is itself the answer. Ask what the manufacturer's schedule calls for at this mileage, then compare it to what was actually paid for.
When were the valve clearances last checked on this engine?
Why ask it
On many engines this is the single most expensive routine service, because reaching the valves means removing a great deal of bodywork and sometimes the radiator. A seller who does not know whether it has ever been done is telling you the interval was probably skipped.
How old are the tires, and what is the date code on the sidewall?
Why ask it
Rubber hardens with age regardless of tread depth, and a tire with plenty of tread and six years on it grips poorly and cracks between the blocks. The four digit code gives you the week and year of manufacture, so read it yourself on both tires.
What condition are the chain and sprockets in, and when were they last replaced?
Why ask it
Hooked sprocket teeth and a chain with tight spots tell you the previous owner skipped the cheapest maintenance there is, which suggests what else was skipped. Chain, both sprockets and the labor together are a real cost you should subtract from the asking price.
When were the brake fluid, coolant and fork oil last changed?
Why ask it
These are time based rather than mileage based, so a low mileage bike can be badly overdue on all three. Squeeze the front lever and look at the fluid in the reservoir: dark fluid on a bike with a spotless exterior tells you the care was cosmetic.
Are there any leaks, and what does the floor look like where it normally sits?
Why ask it
Ask to see the parking spot, not just the bike, because a clean bike over a stained floor answers the question. Fork seal weeping, a wet engine case gasket and coolant crust at a hose clamp are each cheap to spot now and expensive to discover later.
What has been modified, and do you still have the original parts?
Why ask it
An aftermarket exhaust without a matching fuel adjustment can leave the bike running lean, and a rewired tail tidy is where electrical faults are usually born. Stock parts in a box are worth having for resale, for inspection, and for undoing someone else's judgment.
Are there any warning lights on, or any stored fault codes?
Why ask it
Ask before you see the bike running so the answer cannot be shaped by what you notice. A cleared code can come back within a few miles, which is one more reason to want a test ride long enough for the engine to reach full temperature.
How has it been stored, and what do you do with it over the winter?
Why ask it
A bike kept outdoors under a cover collects moisture against the metal, and one parked for months with untreated fuel and no battery tender usually needs carburetor or injector work and a battery. Ask specifically whether it has ever sat for a season without being started.
Is there anything on it that does not work?
Why ask it
Asked openly, this often produces the small honest list a seller will not volunteer item by item: a dead fuel gauge, a sticky turn signal, a horn that only sometimes sounds. Each item is minor, but a long list means deferred attention across the whole machine.
May I see it started from cold?
Why ask it
Insist the engine is stone cold when you arrive, and say so when you arrange the visit. A pre-warmed bike hides hard starting, a weak battery, startup smoke and the rattle that quiets once oil is circulating, which is exactly why sellers warm them up.
May I take it for a test ride, or bring a mechanic to look at it?
Why ask it
A refusal is sometimes reasonable on an expensive bike with an unlicensed stranger, so offer alternatives: leave a deposit, show your license and insurance, or pay a shop to inspect it. A seller who refuses every version of independent verification is the one to walk away from.
What is your price, what comes with it, and are there any fees on top?
Why ask it
Both keys, the owner's manual, the service records, a spare set of levers and any stock parts all have value and are easy to secure while you are still negotiating. At a dealer, ask for the out the door figure in writing, since documentation, freight and setup charges are where the advertised price grows.
Inspecting a Used Motorcycle
Practical guidance for the conversation itself
How to Set Up the Visit
Require a cold engine and say so in advance
Tell the seller on the phone that you want to start it yourself and that it must not have been run that day. A cold start reveals a weak battery, a hard starting engine, smoke from worn valve guides or rings, and the top end noise that disappears once oil is up. If you arrive to find the engine warm after you asked for cold, treat that as information and price accordingly.
Go in daylight and bring a flashlight anyway
Evening viewings hide scuffs, mismatched paint, weeping seals and the exact color of brake fluid. Bring a flashlight for the underside of the engine, the inside of the fairing, and the chain run, and bring a rag so you can wipe a suspect area and come back to it ten minutes later.
Ride it long enough for the fan to cycle
A short ride around the block tells you almost nothing. You want the engine to reach full operating temperature, the cooling fan to come on, and a few hard stops from speed so you can feel warped rotors or a dragging caliper. Take it through every gear, and let go of the bars briefly on a smooth straight to check whether it tracks straight.
Pay for a shop inspection on anything expensive
A dealer or independent shop will put the bike on a lift, check the frame for straightness, read the fault memory, and quote what it needs. On a machine costing several thousand, that inspection is cheap insurance and it also gives you a written list of work to negotiate against.
Checks to Do Yourself Before You Ride It
- Read the VIN on the frame and compare it letter by letter against the title.
- Read the date code on both tires, then check for cracks between tread blocks and uneven wear at the edges.
- Look at the sprocket teeth from the side for hooking, and lift the chain off the rear sprocket to check for slack and tight spots.
- Check fork tubes for pitting and the seals for oil film, then compress the front end and watch it return.
- Look at the brake fluid color in both reservoirs and the thickness of the pads through the calipers.
- Check bar ends, levers, mirror stalks, exhaust and case covers for the scuffs that mark a drop.
- Spin each wheel and watch the rotor for wobble, then feel the rim edges for a flat spot from a pothole.
- Pull the seat if you can and look at the wiring for splices, tape and aftermarket relays.
- Check the coolant level and the oil on the sight glass or dipstick, and note whether the oil smells of fuel.
Reasons to Walk Away
- The title is not in the seller's name, or the seller wants to sell you a bike with a lien still on it.
- The VIN plate looks disturbed, or the number does not match the paperwork.
- The engine was already warm despite your asking for a cold start.
- Every form of independent inspection is refused, including a paid shop check with a deposit held.
- The bike is being sold in a parking lot away from the seller's home with no paperwork on hand.
- Fresh paint or new plastics on an older bike with no explanation of what they replaced.
- A rewired harness with visible splices, tape and no documentation of what was changed.
- The seller cannot say whether the valve clearances have ever been checked on a bike well past the interval.
Costs to Budget Beyond the Purchase Price
- Insurance, quoted for this exact model before you buy, since some models cost far more to insure than their price suggests.
- Registration, transfer fees and any sales tax due at the counter.
- Immediate service items: tires, chain and sprockets, brake fluid, coolant, and an oil change on arrival.
- Any deferred scheduled service the records do not show, valve clearances in particular.
- Gear if you do not already have it: helmet, jacket, gloves, boots and wet weather kit.
- Transport home if you cannot legally or safely ride it away on the day.
