Hello everyone, I really need someone’s help with identifying the year and model of my 1980s ktm. Using the vin number I think it’s a 1989, but I don’t know what model and I’m not even for sure on the year. I only need to know this information so I can be sure to buy the correct parts to get it back to ripen. The vin is KTM890162615

Welcome to forum. Your bike was assembled January 1989. To be able to determine what model it is please provide pictures of the bike.

@DW @bajadog We have established that this bike (see pics above) is a 1989. But what model is it??

@Rangerman is this best for these old girls.
Chains on the wrong side, so definitely pre 90's. Those numbers are weird, I am not familiar with them. Most I know start with vbk...
Had one of these stabs in the dark the other day. Not sure of capacity, but I'll take a stab and say it's a 1989 250 GS

Thank you both for looking at this. If it is a GS. What is the difference between that and a MX?

Re size: There should be a stamp/marking on the cylinder that tells you the cc. If not, then the best option is to measure bore/piston and compare to pistons in parts listings that state the size of the piston. And sorry, I have no idea about the difference between the GS and MX.

Is that the same bike after a decent tidy-up, or is it a different bike, but one that looks like yours?

Are the cylinders and engine parts going to be the same with both models ? Mx and gs? It’s much easier to find the Mx parts.

More than what I can tell ya sorry.
There would be a lot of similarities, but knowing what parts are different is beyond me.
I don't have parts listings pre 1994.
Probably flywheel and stator would be different. If it's running the old sems ignition you would probably want to p-ss that off anyway.
There's a possibility it is an mx with a gs rear guard. How many wires coming out of the stator? Does it have wiring for headlight and tail light ect?

It does have wiring for a head light. And there is a tail light. I can take pictures of all the wiring when I am home if that would give you a better idea.

That would make her a GS as the MX bikes do not have the light wiring included. Then again... who knows if that is the original stator?

May be others know better, but the web site I picked the picture from said it was a 250 E/XC. The two models listed in a vintage KTM website says they are 250 MX and 250 E/XC. If you have original headlight wiring it would be the E/XC.

Gotcha, I’m starting to think the writing isn’t original because I ordered a parts manual for mx and enduros, and the part numbers don’t match up. I was hoping the Parts manual would help me clarify what bike It is for sure and im still yet to be sure on the model.
