shmaides Posted February 2, 2012 Share Posted February 2, 2012 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 Link to comment Share on other sites More sharing options...
clarke Posted February 4, 2012 Share Posted February 4, 2012 Post a pic of the bike if you can + maybe someone will recognise it? Link to comment Share on other sites More sharing options...
Moderator Cynic Posted February 4, 2012 Moderator Share Posted February 4, 2012 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. Link to comment Share on other sites More sharing options...
Moderator Airhead Posted February 4, 2012 Moderator Share Posted February 4, 2012 It is a DT125, cant you see something on the cylinder that says 123cc (for example) Link to comment Share on other sites More sharing options...

PhilDawson8270 Posted February 7, 2012 Share Posted February 7, 2012 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. Link to comment Share on other sites More sharing options...
