OK, I know it is a KTM, but today stuck in traffic trying to get out of London it totally overheated. The overheating warning screen came up which I’ve never seen before, and after a couple more minutes it shut itself down and I had to push it off the A4. It did it briefly yesterday near home, so I let it cool them popped straight home, check coolant levels, oil level, everything is topped up. The only major change I have made is the full Akcrapovic system, but it has been fine over winter with that. anyone got any ideas and things I can check over the weekend before I go to the dealer? I made it home after I let it cool, it is just heavy traffic and obviously the weather, it has been fine before it got warmer. Now the engine light on dash is on all the time;(
Cheers

Yeah, good point, yes I got it mapped, I also just realised I’ve got the KTM/RAC cover, so they popped down, fuses ok, nothing blocking the fan, maybe a sensor, but yeah could be lean. I’ll get it recovered during the week to the dealer. I hope I haven’t damaged anything, seemed fine riding back, but worried about the engine light stuck on. Still got my grom to have fun on though. Thanks

Went out yesterday and had this a lot, although the engine did not stop and it was ok once I got going.
On closer inspection today, the rad is clean except where the fan is located (high centre), which almost seems to suck crud into the rad. I have used the bike a lot through winter (mud etc etc) and I think this part of the rad escapes cleaning as it is relatively well protected and thus difficult to clean/get at. Also can't blow water through backwards to clear stuff out easily.
So when the fan comes on, it will be trying to suck air through the most blocked part of the rad.
I just cleaned it out and ran it before and after cleaning on a long idle. Overheated in the first instance after about 10 min. Once cleaned made a big difference and only went up to about 6 bars.

Burp the radiator as good chance its just air trapped inside. Could also be the thermostat and not for the first time...
