Yamaha lists a $4,999 starting price, but that is not an out-the-door quote or a reliable valuation of a particular used bike. Use the specifications below to compare models, then verify fees, condition, title and service history on the motorcycle you are considering.

Yamaha’s feature page lists an LCD instrument display, LED turn signals, a single LED headlight with dual position lights, a diamond-type frame and a 22.6-inch asymmetrical swingarm. Yamaha describes the engine as having a 180-degree crank and an integrated counterbalancer; those are manufacturer descriptions, not independent test findings. See Yamaha’s 2023 specifications and feature page.
2023 Yamaha MT-03 price: MSRP versus what you pay
Yamaha’s model page currently displays a $4,999 starting price. Its pricing notices say the displayed MSRP excludes taxes and listed charges, and that dealer prices may vary. Yamaha’s 2023 specifications page likewise says MSRP excludes tax, title, preparation and destination charges, with actual prices set by dealers. Ask the seller for an itemized, current out-the-door quote rather than treating the starting price as the final cost. Check the Yamaha model page and specifications page for their displayed terms.

How to evaluate a used or remaining-stock MT-03
Model specifications cannot tell you whether an individual motorcycle has been maintained, damaged, modified or stored well. Inspect the actual bike and have a qualified mechanic assess concerns.
- Confirm identity and paperwork. Match the VIN on the motorcycle to the title and available records. Check title status and ask about any liens, ownership gaps or registration issues before paying.
- Review maintenance and history. Ask for service records, receipts and an account of crash damage or repairs. Confirm which accessories are included and whether modifications have supporting documentation.
- Check the cold start and instruments. If possible, see the motorcycle started from cold. Watch for warning lights that remain on, unusual noises or visible leaks; ask the seller to explain any warning or repair history.
- Inspect suspension, brakes and tires. Look for fork or shock leaks, assess brake condition, and check tire tread and date markings. A tire can need replacement because of age or condition even if tread remains.
- Inspect the chain, sprockets and controls. Look for wear or damage, and check that the controls and lights operate. Compare the installed equipment with what the seller says is included.
- Get an independent inspection when needed. If records are incomplete, a check raises concerns or you are unsure what you are seeing, arrange an inspection by a qualified mechanic before committing.
- For remaining stock, clarify the deal in writing. Ask the dealer for the full price with fees, the motorcycle’s status and any warranty coverage that applies to that specific unit. Do not assume a model-year specification or general manufacturer page establishes an individual bike’s warranty or condition.
Could the MT-03 suit a beginner?
The specifications offer useful fit factors, not a universal answer. Yamaha lists a 30.7-inch seat height and 373-pound wet weight; a prospective rider should consider whether they can comfortably manage the bike at a stop and at low speed. The 321cc engine, fuel injection and six-speed gearbox describe its configuration, but do not by themselves establish how easy it will feel to a particular rider. Take appropriate rider training, wear protective gear and assess fit and control in a safe, lawful setting. Yamaha’s safety notice recommends a helmet, eye protection, a riding jacket or long-sleeve shirt, long pants, gloves and boots, and advises reading the owner’s manual and product warning labels before operation.
