That dude can ride. He took a pounding, that is for sure.
Smaller? A little but not by much. A Road King is 93.7" long and a Sportster is 90.3" long. Seat height on a Road King is 26.9" and it's 25.7" on the Sportster. The biggest difference is weight where the Road King weighs in at a hefty 763 lbs compared to the significantly lighter Sportster at only 565 lbs.I think a lot of people give the sportster some crap just cause it's smaller is all.
A rather silly thing to do considering that whatever motorcycle you happen to be riding at the moment is the best possible motorcycle for you at the time regardless of brand, size, or any other consideration least of which is what someone else is riding.....the problem is that Sporty guys (some) have a need to convince "big twin" guys that their bike is actually better.
