So I purchased a new 790 duke yesterday and drove around 100km with it. I was riding with some Levi jeans on and after about 30 minutes I can feel the heat from the engine getting unbearable, I just thought **** this is hot and can feel my left leg stinging anyway so I got home later to find that my left leg looks like it's been sunburnt and I put some aloe vera on it and in the morning it's gone down a lot the redness but I've got blisters from the burn now.
Now I don't know much about bikes, to be honest, other than they are lots of fun, my previous bike was a 390 and I got bored after a year and wanted something with a bit more power so decided on the 790. On the 390 I could hug the tank with my legs and never experience any sort of burning wearing the same jeans I wore yesterday.
So as to my questions. Is this normal and I just need to buy proper protective trousers to prevent it happening again? Or does my bike have a cooling problem or something? I did have one of the black bits in the bike pop off after a few kilometres from a stop light when I webt off (see pic below as I don't know the correct terminology to explain)
It wasn't like I was hugging the tank or anything and as said it was fine for 30 minutes just after something happened and it was like heat from engine x100. I've ridden it since and the same thing, starts off okay then after 30 minutes it gets really really hot.

Thanks in advance for any help or suggestions, I didn't buy it from a dealer so it's not as simple as go back to the dealer and get them to check it and I know nothing about repairing or fixing the issue another way.
