I guess I must just be lucky with my ‘09. I’ve had it in 100 degree temps and haven’t ever been overwhelmed by heat from the bike. The boys ain’t been gettin’ roasted. Although, the other day, I was without a vehicle and rode to my workout class in the morning and rode home wearing only shorts and a shirt. (Sacralege, I know, but I was burning up). Anyway, on the ride home out of proper riding gear, I noticed a little heat coming off of the motor. Was kinda nice, actually, cuz it was a chilly morning.
The bottom line is I haven’t ever had a problem with heat. I asked the previous owner (a friend) and he never noticed a heat problem either.
