HI FIRST POST I JUST BOPUGHT MY SON A YAMAHA MOTO-4. THE FENDERS ARE LIGHT BLUE AND THE SEAT IS DARK BLUE.AND ITS IN PRETTY BAD SHAPE BUT IM GOING TO FIX IT UP FOR MY SON. MY QUESTION IS IT HAS NO WHAT SIZE IT IS JUST MOTO-4 SO HOW DO I FIND OUT WHAT YEAR AND SIZE I BOUGHT IT OFF OF SOMEONE AND THEY COULD OFFER NO HELP. SOME OF THE NUMBERS I TOOK OF OF IT WERE 55X-069755 AND 850cm3 . ANY HELP PLZ THANKS ROTT

 

I also have an old yamaha moto 4 200 it was my first quad but its now in the blown up quad graveyard im my garage and im gonna rebuild it sometime. But there should be a number on the engine and the frame and your dealer can tell you what it is. There is a way to tell with the number on the base of the cylinder but 850cm3 my quadracer says 499cm3 (i think lol) and its a 500 so thats right, but 850cm3 are you sure you saw the number corrrectly?

 

LOL ON THE FACE PLATE OF THE MOTOR IT DID SAY 850CM3 BUT ON THE CYLINDER IT SAID 22K 79CM3 SO ITS AN 80 THATS ONE ANSWERED THANKS FOR THE REPLY NOW TO FIND THOSE NUMBERS ON THE FRAME THANKS AGAIN ROTT

 

A friend has one of these and it is a 100 cc. I think they were made in several engine sizes. He did a rebuild, so I know you can still get parts for them. Go to a dealer with your info, and they should be able to tell you.

The worst thing about this bike is NO REAR SUSPENSION (and very little front)!! The tires are the suspension. Light kids get bucked around all over the place.

 

thanks i just got the number off of the frame and gonna call a dealer
thanks again rott

 

where it says 850cm3 probably means how much oil should be put in since on the side of my blaster(near kick starter) it says some number i dont know off the top of my head cm3, that is how much i use.
