Ok so i bought a bike a few months back, just an offroader for use in the lanes

Was sold as a Dt125, but my mate says its not a DT, maybe a YZ? His dad recons its neither, possibly an IT?

There are no lights, but there is a bracket for a footstand. My mate says the shocks and discs are not from a DT as they are larger than usual.

The engine reads 'Yamaha 3BN' then 'Y-3' on the head. Does this mean anything? Or do i need to find a chassis number etc..

I'm a complete ammatuer when it comes to bikes... as you can tell lol

I need to know what bike/engine i have as i need to buy a head gasket.

Thanks in advance

Post a pic of the bike if you can + maybe someone will recognise it?

A 1991 DT200Rb acording to the engine prefix. Broadly similar to a DT125 of the time.

That doesent necessarily id the bike though, just the engine thats in it. you need to look at the headstock for the frame number. Even if its a motorcross bike it should still have a frame number there.

It is a DT125, cant you see something on the cylinder that says 123cc (for example)

Pics would be a bonus

Ok guys heres a pic..

3BN y3, same markings i had on my 89 DT125

and pics looks like DT for sure.

To be 100% sure, you could just call Yamaha up, and give them the frame number, they will tell you what the model is within seconds.
