Update:

I topped up the expansion tank to just over minimum with de-ionised water and have since not had any issues.
When hot, the level is just over halfway between the min and max marks. Bike seems to be running cooler too: get's to about 101, fan comes on and only continues to heat up to 102 then cools down to 95/96.

So all looks good! Hopefully it stays that way!

Thanks everyone for the help and advice  :020: :046:

This happened to me after installing some headers (17). It seems as if when I put the right side fairing back on, I pushed the radiator cap halfway open by accident. Didnt notice this until I pulled the fairing and tightened the cap and went to the fit the fairing back on, i heard the pressure release from the cap and thats when it all made sense. Make sure your cap is on tight  :001:

Had a look at the cap and all seemed good. Hadn't been working on the bike before it happened.

Since I topped up the coolant, no issues so I'm happy to say it was a one-off :)

What kind of coolant did you use? In there a specific brand that I need to put in the bike or any recommendations?

If you are only topping up a little some distilled water will be fine. Other wish if you are using more grab a bottle from BMW coolant.

As I only needed the small amount (<250ml) for the expansion tank, I just used deionised water :)

Happened to me yesterday, drove to work and parked up, when it came to going home I'd got a fairly large blue puddle under the bike I've only done 200 miles on it from new so I need to investigate further.

Looks as though it was caused by an airlock, rad was full but expansion tank was empty, topped it up and got a lot of air out of rad whilst running with cap off, seems to be ok now.
