Engine size should be stamped on the back of the cylinder (249cc, 124cc, etc...) As far as the year, see if a dealer service department can help, or call Yamaha USA customer care.

Year modal of dirt bike fram vin 583-004045


If that is all your vin number has to offer, it doesn't follow the rules of street bike vin numbers, usually, the first letters are a code, then the first digit is street or dirt, 2nd is model, 3rd is a letter for liquid or air, 4th is engine size, 5th is HP, 6th is check digit, 7th is year, the 8th should be a letter for the city of manuf.and finally the series number. All these digits are codes, you can look them up on line. Hope this helps.

I'm trying to find out what year, model and engine size of a dirt bike i have. The # stamped on the neck are 22w-009347. Can you help me? on one of the engine covers say yamaha.


You can call yamaha and give them that number and they will be able to tell you everything about the bike. You can usually look right by the oil fill and it will give you the size. It will say like 245cc, that would be a 250. But the dealership can tell you exactly what you are looking for.

I have a yamaha dirt bike that someone stole and


Check the igniter. Go back to the dealer and ask him to see one. Then go back and find it on your bike. Yamaha's usually have them under the seat, or left side. But I don't know exactly what year you have. Run the VIN on the frame under my tips and tricks is a web site that'll break it down for you.
