If you are trying to find the CC size of the bike it will say on base of the cylinders somewhere. There is also a number on the motor and it should match the frame.

I need parts but I can't find my VIN info. Make and model. I tried multiple vin decoders and they all said invalid vin. #L5NPMSCG75TS00316 Please Help me!!! Jen

It comes up as "The VIN you entered (L5NPMSCG75TS00316) has an invalid check digit. The check digit is a value encoded into the VIN in order to protect against altering VINs illegally."

So the bike MIGHT have been stolen, and the VIN altered.

I CAN tell you from the VIN it was made in China, and the model year is 2005.

And the "7" should be a "2"

You MIGHT have misread the "2" as a "7"

IF you put the VIN into a decoder with a "2" instead, I get back that it a "2005 TAOTAO"

The VIN decoder I use does not accept the number given. There are one or more errors in the set of numbers. VIN numbers do not use the letters " I, O and Q". Bear in mind the digit "2" could be a "Z". Kawasaki vins do not have hyphens. All vins are 17 digits. I changed the vin to JK0....... (without the hyphen), and had no luck. Then I tried JK0KXRH13LA003Z01also with no luck. The best I can tell you is that the bike is a 1990 model. Double check the number and look for possible alterations someone has made, like changing the numerals 11 into an H. If you come up with corrections, go to the website below and you can check the vin yourself. The image below is what I have been getting. Please take a moment to rate my answer.
