Do you have wind/bar blockers on your bike?
I've heard those make more of a difference than the heated grips.
Was talking with the owner of the local bike shop and she said every year she keeps hoping someone will come out with a good solution for her to stock.
Yeah, unless you're tracking, I never ever get the appeal of supersports on the street.
Even in the twisties or canyons, you're in what? 3rd gear?
The only thing I can see is the ergonomics that let you drop a knee but you can get those in other bikes.
