speed four 600

Hi All,
Hope you are all well. I recently bought a triumph speed four 600. After going for a ride earlier I noticed when I got back some fluid leaking onto floor. it was coming out of a tube that fed back to the coolant reservoir under the seat. I also noticed the temp of 188c when I turned key back on. The engine was hot as was the radiator. I was only out for 30 mins. I'm very green when it comes to motorbikes. Can anyone please help, as I want to go out again soon, but I'm worried I'll damage the bike more.
