I have heard a few posts around here about the heat coming off the engine and I agree it's more than some other bikes I've owned. The heat on the back of my leg bothered me enough to see exactly what the different temperatures looked like. So here it is all in Celsius:
Ambient temperature was about 20 degrees, bike was allowed to run up to temperature and maintained between 100-103 degrees (I have the full Akrapovic system)
Rear cylinder - 130-133
Rear header - 230-250
LH pipe at rear heat shield - 76
RH pipe at rear heat shield - 77
Rear header on heat shield - 140 (I also have a layer of wrap in this location)
Clutch case - 66
Timing cover - 65
A also included some FLIR images I did at the same time. Temperatures above were taken with a more accurate laser unit.

thats really cool! did you start taking images before it warmed up? it seems like the coolant lines are not that warm until you zoom on them.
The bike was fully warmed. The problem with FLIR is that the colors are always recalibrated for the field of view it currently is in, so it can be deceiving. That's why I used a better infrared laser to get the posted readings. I did the coolant system as well in the same way. Coolant into the rad was 98.1 and out was 69.1. FLIR is good to give a bit of an overall scan.

Jimmymac: How much of the pipe did you wrap, just the rear pipe under the heat shield. Are you happy with the results

heat

Be glad that you have a Supersport. The V4 is comin much hotter than the Supersport. Thats normal for a Ducati.
Last year @ WDW I ride my SSS with shorts during the traditional Ducati Corso along the coast. Believe me, the bike was that much hot that i was sitting on it like having the trousers full. If you ride you don´t feel it. But when you keep standing over and over you feel it much more as you want.

I am guessing the heat issue is related to the cat? I suppose the catalytic converter couldn't be moved further out where the mufflers are and away from the rider? (Meaning a traditional muffler where it's in the back of the bike next to the swingarm.)

I have the Termignoni exhaust with no cat, still gets bloody hot. Do not think there is much you can do, it’s a V twin, have exactly the same heat on my KTM V twin maybe even worse.

I only wrapped under the top shield. I had to remove the wrap the first time because I couldn't get the shields to fit back on(not enough room with the spring) So I had to compromise by simply using strips of the wrap overlapping lengthwise. I don't find that it made any noticeable difference to my burning legs.

Any of you guys have any experience with the monster 1200? Is it about the same for temperature?

Installed the CF belly pan from Ilmberger and guess what, it made the bike a lot less hot when sitting in traffic. looks great and reduces the heat I feel. very happy

What about ceramic coating the exhaust? Anyone tried that?
I have the akra race with an internal thermal barrier and external nano ceramic coating. It still gets warm but not as bad as previously. It does cool down almost instantly when I turn the engine off though. I can't afford a once off use thermal gun so I don't know the true temps but I can touch the pipe with my finger and it doesn't burn me.
Other than the plus 50% heat reduction it also gives upto 5% hp because the heat is trapped in the pipe and that pushes the hot gases out faster.
However, removing and installing the front header is a little bit of effort. Depending on the price of your specialist shop I'd suggest it's worth it. It's the internal thermal barrier coating that cools it, the external is mostly cosmetic. No doubt a salesman will tell you differently.

Excellent answer. Thanks Amos.

If you have a catalytic converter then you shouldn't waste your money because the cat is designed to keep heat to burn the excess emissions. I doubt an external coating on a cat will give you the result you desire.
Thats sounds reasonable, yes. It’s just this huge lump of metal so an excellent heat retainer. I’m still waiting for an after market exhaust that I actually like the look of and wouldn’t likely have bothered before to get anything done, but good input.
