I'm trying to understand why people like 100s and 125s and such. I read all the time on here about folks in their late teens and 20s "upgrading" to a 125 from a 100, And i'm trying to figure out why they don't go bigger. I rode a 125 for an afternoon recently and couldn't wait to jump back on my 250, i'm 5'10 and weigh about 160. Did i miss something? I'm not talking down to anyone or being a dick here i'm just curious. Obviously there must be something to them since their so popular. Maybe i'm just to big for em.
