Motorcycles are a common target of theft, so verifying that a motorcycle is not stolen can take some preparation. That should be part of your time looking over the motorcycle. This is not always easy as you have to get the VIN before you check on it. Some services exist online to look these up, but there is no official national registry. Try your local DMV if you suspect the bike to be stolen. If you purchase a stolen bike, you’re out the money and the bike.
Do not forget to bring a flashlight and way to clean your hands – hand sanitizer and a towel at the very least.
Also, bring the advertisement, or a copy of it, along with you when you view the bike. This will keep you from forgetting the previously stated details. You can also record information you learned during your research here so to use it as a central resource during your search.
Walk around the bike a few times glancing at it from different angles to see the light reflect off the surfaces. Sunlight is great for this as it will highlight such defects quite clearly. Examine the bodywork of the bike looking for scratches or dents. Check areas like the rear of the tank for scratches from zippers. Are there any stickers in unusual places? Could they be covering scratches, dents or even holes? It’s possible, so use your eyes. Check for signs that the bike has been dropped; scratched - and often badly repainted - engine cases, foot pegs or exhaust pipes and brand new turn signals are some good clues. Pay special attention to the condition of the brake and clutch levers, bar-end weights, straightness of the handlebars and instrument cluster. Signs of damage here could mean more exists elsewhere. If you do find some damage, ask the owner to clarify it for you.
Mount the motorcycles, hold the front brake and bounce the front suspension; it should feel smooth and firm. Get off the bike and check the fork tubes for signs of rust, pitting, scratching or oil leakage. Any of these could mean a complete fork rebuild.
