Hardcore Rider - If they have a car and are not transporting anything larger than a couch, will take the motorcycle.
Daily Rider - Commutes daily on their motorcycle, but will take the car if the weather gets iffy.Fashion sense: Low to Medium. Wears either turbo-bright neon hi-vis or dull but safe motorcycle jacket. Has a personal conception of what "cool" is and hopes others appreciate it. Is often wrong.
Fashion Sense: Medium, usually biz-cas.
Rides: BMW, Suzuki V-Strom, Triumph cruiser/standard, Suzuki Bandit, something old and lime green
Street Biker - Often rides only at night because the roads are open enough to ride fast. No money left to go to the track because it was all spent on a carbon fiber muffler stay. Where legal, removes the helmet within two blocks of mom's sight.
The Grand Tourer - Always seen as a couple with the husband up front and the wife riding pillion. For this type of motorcyclist, weekends are made for riding. Usually the farther the better. Has chosen adventure on a motorcycle rather than an RV because they haven't given up on life yet.
Fashionista - Not a true motorcyclist, but has either ridden or posed on the back of one.
Like John Audubon, I am constantly seeking new classifications of bikers and so could use your help to refine and add classifications. Unlike Audubon, I did not shoot and then eat my subjects.
