Coolant pouring out!! SV1000S

[Adam80UK]

I had recently topped up the coolant, not over full at all, today riding home the temp got to 101 then when I got off outside my garage I suddenly noticed coolant was pouring out of the overflow pipe

I assume it's the overflow pipe anyway, one of the rubber ones hanging down.

Any ideas please?

Is it the pipe from the header expansion tank?

Is the expansion tank located by the radiator or somewhere else on the bike?

When cold the coolant in the expansion tank should be about half to two-thirds full.There are normally two lines on the tank - a 'LOW' and a HIGH' marker.
