Thank you Mig, you have the same view as me. I'm probably going to buy the new 2013 hypermotard for commuting duty this upcoming summer. We have similar weather in Florida as you. I love my 1199, and won't sell it. But God-.......-damn it's hot in the middle of a Florida summer.
For those blasting a guy for weighing in a bike's heat when purchasing all I can say is what is wrong with that? The guy lives in Kuwait, so a bike's heat management is a legitimate concern when purchasing.
I can't say if it's hotter or cooler than the 1198 or 1098, but gunny is dependable in his posts so I feel his assessment is a fair one.
I can, however, say that this bike is indeed hot in traffic. The absolute best thing the OP can do is actually test ride this bike for as long as possible and even a couple times to see how the perceived heat it to him.
I personally believe you will love this bike, but there are circumstances (stop & go traffic) where it will be unpleasant.
I'm done.
