The Sportsters were given that name for a reason.
They were the first semi-reliable Sport Bike and became the racer/dragger of choice.
I have love for Sporty's after hearing stories from my Grandpa scrapin' floorboard (which was like scrapin' pucks back in the day). I even have a fairly modded out Nightster in my garage these days.
Needless to say Gramps loves the fact that I ride a Sport Bike.
