ktm 525sx to exc swap?

found a great deal on an 03 ktm525sx chassis, no engine though. I was thinking about buying a used 525exc engine and swapping it in.

Is it realy going to be that easy? I definantly need to run lights to get a plate for it.

Bolt in excepting swing arm pivot bolt changed size around 2004??? Bushings or drilling it out are common fixes. I think Jar44 (or similar name) has a hybrid RFS thread in the bike build section. I'd bounce it off him to know for sure.

thanks for the link, unfortunately that's a build with a newer frame. My main concern is if the SX electronics that come with the frame will work with the EXC engine.

The engine should basically plug in, but you will need a bigger DC R/R. If you get an 04+ engine you will need a bushing to sleeve the rear engine hole down for the thinner swingarm axle, KTM sells them or make your own.

Some of the 03 525 SX CDIs came with a 1000 RPM higher rev limit which contributed to them blowing up, I think the part number ended with 100 and the one you want is 200, or the other way around.

You wil also need a new chassis harness if you want to plug in lights, I'd get OEM KTM parts from the Euro spec EXCs.

The RFS section on KTMtalk has also the relevant infos and part numbers so do some research over there.

I think Jar is a real good resource for you but Lukas is great too. ktmtalk will get you specific answers too but between the two guys mentioned I bet they have all the info and more than you could ask.
