Sportster 

All-time best street bike ever built. Introduced by Harley Davidson in 1957 to combat the invading British Triumphs, Nortons and BSAs on the track and on the street. The best selling middleweight motorcycle in history.

Unique among Harleys, the Sportster engine and transmission are in one case, whereas the so-called Big Twins have a seperate transmission case. Pre 1986 Sportsters featured iron heads and are called (DUH!) Ironheads. '86 to present are the next generation Evolution, or Evo, Sportster and feature alloy heads and a 5-speed transmission. The most recent models feature rubber-mounted engines.

Sportster-based motorcycles have dominated flat-track racing since the late 1960s. Many early choppers and customs were built from Sportsters, as well as land speed record bikes.

Calling a Sportster a "girl's bike" or "Shortster" may result in a visit to a dentist.

Lots of Yuppie Softail wankers ignore the fact an 883 Sportster makes almost as many horses as their Evo Big Twin, but the Sporty is two hundred pounds lighter. No contest, Sportsters kick ass!

Sportster Knee 

An overextended knee caused by attempting to kick start an Ironhead Sportster. A bike that was notorious for high compression, and kicking back when attempting to start. Young punks these days don't know how good they got it, and shouldn't knock anyone who's ever owned an old XLCH.

Man, I'm sorry, I can't go with you. I got Sportster Knee!

Little squid on your busa, I'd kick yo ass if it weren't for this damn Sportster Knee.

indie sportster 

Pretty much an indie hipster who enjoys outdoor sports. They still have the style and the attitude but they wake up on Saturday mornings to go biking or hiking or kayaking...

Natives are usually in San Francisco or Seattle - rarely see them in New York.

"Terence is such an indie sportster - with those ironic sideburns and that hunger for the wilderness"

The Sportscenter 

Having sex in doggy-style position while watching Sportcenter late at night making sure to climax exactly when "Da da da—Da da da" is played and yelling "Da da da—Da da da" while thrusting to the rythms of the forementioned "Da da da—Da da da" before rolling over and fading into sleep during the Highlight of the Night.

'' Yo guys, I was at this engineering competition in an hotel and I totally did The Sportscenter to this girl while my roomate was passed out in the other bed"
