Can someone help me identify this bike?

Recommended Posts

My buddy just traded his mountain bike for this ‘ol beauty. I’m not having any luck finding much about it. Does someone recognize it?IMG_1969.jpgIMG_1965.jpg

I’m taking a guess just for fun...

it looks like 80s cr125/250 with an xr200 swap or something. 

How’s he gonna shift with the shifter all the way down there??

Looks kinda like mine . It's either an 85 or 86 cr with a 200 motor. Mines an 85 cr125 for reference.

the motors look extremely similar from the left side. Is yours a 2 stroke motor or did you swap it?

It's definitely an XR motor (probably a 200), stuffed into a CR125 frame (love those twisty fork boots!).  In case you are wondering, the motor is a 4-stroke.

Thanks for all the replies. All I know is that the engine is not the one it came with. I'm just starting dirt biking and my buddy (who's bike it is) is brand new and knows nothing so any info is much appreciated. The knowledge in this forum is damn impressive...

The frame is from a 1988 CR as it is white, the shroud is some other year the rear wheel looks like vintage CR 86 or earlier because 87 + was disc.  The motor is XR for sure I would guess a 200.

The vin says 86 cr125r

This guy ran the frame vin, and it gave you results for that.  And it appears to be XR200 Engine.  I would like to see pics of airbox to carb to see how that was handled.  The air intake & no lower frame or skid plate would concern me.  If the frame is not built right, it could pull the engine cases apart quickly.  Being newbies, it should be looked at by a competent frabricator.

A lack of frame component is extremely concerning. That doesn’t make sense...

I seem to remember that some of the XR200 frames did not have a cradle. The engine is a stressed member. It did however have a substantial bash plate that would stiffen the chassis. The design of the XR and CR frames is different, so could possibly apply stresses in a different direction. 

Just check that any welding is up to spec, and fabricate a good alloy bash plate. Then just go and ride it :-)
