Two years after the Ironhead retired, Harley began crafting both 883 cc and 1200 cc versions of the new engine. The only real differences between the two were price tag and bore. Beefing up your 883 to 1200 became so standard people look at you funny if you don't do it. Harley-Davidson also debuted the Sportster Hugger in 1988 and changed the bike's image dramatically. All of you out there who hate the Sportster label of being a women's or beginner's machine have the Hugger to thank for that.
