Yes, it needs to be an aftermarket unit. I can't use the 1978 model swing arm because it is a pre 1978 class.

Matt Park Just did it with a 250/400D DG Swingarm I sold him, he said it was quite easy and the bike is up and running perfectly.

 The 125 is 20mm narrower at the pivot bit the same at the axle .so to do it right you need to bend the side arms somewhere.

I'm pretty sure that the 125 has a smaller dia. axle as well
