I've noticed that too, I'm not a biker. But I do like classic cars, quad bikes and boats. I understand why bikers like the idea of open air riding, seems cool! But what is with the hammy bodies? I see lots of patched and non-patched bikers in my area and more often than not they are hammy as fuck. Lose some weight! Even on a car it helps with performance, kilos lost equals more performance.
