I've run my 750 in Italy on a couple of occasions, in weather hotter than we're having now.
So hot that stopping anywhere, even for an instant, required a shady spot.
...... its natural habitat ?
I would agree that the heat doesn't seem to be a problem .. as long as you're moving.
I generally kill my engine if I'm expecting a longish wait at traffic lights etc.
Mostly that's to stop overheating, but it also reduces city pollution a micro-tad, and shows a social conscience re. the unbaffled termis.
On a related issue...
When I bought my bike, it had a full bellypan which enveloped the front exhaust header.
The heat retaining effect of this was very noticeable, with great waves of hot air rising up at me whenever I stopped.
A smaller, Monza type which leaves the header exposed is a better bet, I reckon .. as is now fitted.
