+1 with Mick.
I ride regularly in shorts if I'm just putting around (yes I wear full gear on spirited rides) and am not by any means actually burned. It get a little hot on the insides of the ankles/calves but not even close to unbearable. If I'm in full gear I don't feel a thing. 2020 poverty edition with remap and "Phil" exhaust.
Disclaimer...I'm in the northeast (MA) so it's not exactly death valley here, but it still gets hot in summer. And I don't really enjoy riding when it gets over about 90 so she stays parked in those temps.
