I have a 2024 six days one and wondered has anyone done this and if so, what is needed. Is it just a case of wheels, spacers, tyres and obviously different sprockets?
I had a 525EXC in Supermoto trim way back. I’m pretty sure that was about the extent of the changes.I have a 2024 six days one and wondered has anyone done this and if so, what is needed. Is it just a case of wheels, spacers, tyres and obviously different sprockets?

24 onwards have different rear spacers but can be made to fit using the right ones.So, would it matter what year KTM 500 exc f the wheels came from if I could find some used ones or would it be better having some made as there's a wheel builder about 5 miles from where I am?
Thanks Roti, that's good to know. I could always get some spacers made up if I ran into any problems24 onwards have different rear spacers but can be made to fit using the right ones.
Basically 12-23 are the same bar certain front spindles on random ones.
Sam at SMX Offroad has them in stock.Thanks Roti, that's good to know. I could always get some spacers made up if I ran into any problems
Up to 2023 are all the same rear. They changed the swingarm from 24 onwards.Ok, I've only just found out that those on eBay are from a 2023 350 exc f so nit sure if they share the same swingarm.







That looks the nuts!I did this a long while ago to my 530 EXC.
17" wheels with a larger brake disc on the front and a new caliper support bracket.
I bought a new digital speedo cable so that I could leave the sensor attached to the bracket if I was swapping wheels around.
The piece of wood under the back wheel was to stop it falling over on the original stand.
I purchased a new stand and cut it down to suit, then I had two options depending on what wheels I had fitted.
My rear 17" wheel didn't have a cush drive, which I would say is recommended if you are going to use it on road for any length of time.
Without the cush it can feel quite coarse.
