Engine Temps?

Does anyone know what the temperatures are for the bars? In other words....


1 Bar = __ degrees
2 Bar = __ degrees
3 Bar = __ degrees
4 Bar = __ degrees
5 Bar = __ degrees
6 Bar = __ degrees
7 Bar = __ degrees

8 Bar = __ degrees

Keep the rubber side down!

Manual states the following



8 bars would be 120C, not sure about the others

I’ve hit this once in London when it was 39C, combined with my coolant leak and heavy traffic, pulled over immediately and shut the bike down to let it cool off.

I explained this to the dealer and said that I was concerned that something may have happened internally. Apparently he’s been working with KTM’s for nearly 25 years and didn’t seem worried at all, he just smiled and said you’d be surprised at how hot they can run.

Observation is the greatest source of wisdom.

At the time I wasnt sure if that made me feel better or worse to be honest.

However theyve found and fixed the problem in half a day, this has been going on for months with the previous dealer, infuriating as it was something so simple.

Fingers crossed it doesnt happen again.

My old man is a diesel mech engineer and actually told me the same thing, he said with modern machining and materials it has to get extremely hot for long periods of time before it starts breaking things and the manufacturers will usually set the alert thresholds much lower than that anyway.

I on the other hand am mechanically inept

I not often saw My Duke above 4 Bars, When the Fifth bar appears the fan still run.


On my Z750 the fan began to work at 106C and stop at 96C but it was the engine temperature on the digital instrumentation not the coolant liquid temperature;
I ask myself how take the engine temperature on the duke ?

hahaha, I'm sorry..


My '06 Husky SMR510 didn't come with a fan, PO had one installed with a switch, I had that switch on, more often than not, but I wasn't being too gentle with the bike..

I bet we could figure out a good approximation of the temperatures using a handheld "laser dot" thermometer pointing at the coolant header going into the tank - at least for the first 4 or 5 bars or so.

I think it might be difficult to get it go much higher while stationary on closed throttle doing nothing - but it could heat soak higher.

Something to try when someone's got an hour to kill on a weekend?

Yea, I have the manual also! I am looking for engine temps just to compare. My old bike was flashing as overheating at 259 degrees F. Curious as to what the KTM parameters are for their bars. If anyone finds it anywhere, please post up!

Keep the rubber side down!

@Chic - I actually intend to do this. I have a reasonably accurate infra-red laser thermometer that I can calibrate for different materials - I just haven't had the time as yet.
