Always looking for an excuse to ride somewhere, I noticed on the internet a car and bike show in my area. There are to be awards for bikes in different classes. The classes were; Sportster, Touring, Import, Custom, and street stock. I have a nice bike and I am thinking about entering but I don't know if I would be classed as Custom or street stock. My question is; what defines custom and street stock? Is that determined by the show or is there a common definition in the bike world known to all but me? My bike is regular bike, no custom paint but lots of extra chrome accessaries. It's my bike I ride everywhere and I'll ride it to the show if I enter.
