So, rode in shorts and cooked my right leg. Yeap, that is the gist.
In the summer, can't ride in shorts or the sun will burn the knees to a crisp, in winter, when one can finally ride in daytime, it is the radiator fan output that broils the leg. I guess, you can do it on a highway, maybe a local road with a wind removing the heat... But if you get stuck in traffic somewhere, or a long traffic light, it will cook ya.
Maybe R version has better leg position in comparison to G, further from the radiator, but, who knows, maybe it is even worse. On G, I can kinda keep my right leg on the outmost peg position to help to move the leg from the directed hot air from the radiator, but it is possible that on R, it might, be in that position to receive the hot air cone, and moving a leg will not help ya. I don't know.
Another issue is the Competition Werkes exhaust, it is so short, even when the bike is stationary, can't really keep my leg on the ground anywhere, closer to the front wheel, the radiator gets me, closer to the rear wheel, the exhaust bites... Basically, no good position. You just take turns to bbq the leg in places where it is not yet as well done.
So, guys, no shorts on the Rocket.
