Actually I witnessed about an even amount across the board
I was out on the one day when it was 35 - 40F and I seen cruisers and sport bikes alike. Lately ive been taking my truck cause im waiting for my heated pants... wimp me - yeah sure
But I have ridden with jeans and a light jacket in the teens - and the only thing that happens is you get cold and when you get cold you get mad and angry and drive like a maniac - i dont want to do that - so ill wait for the right gear
