last summer, an '06 FJAXWQULERGGHYQZ Electra-glide, $20k+ bike. Shook like a paint shaker at low RPMs, with rubber mounts. Twin cam engine. once you got it up to speed it smoothed out, but was a bear to maneuver, and heavy ass sum' beech too, My 'busa now, and then my GSXR 750 were/are SOLID mount I4's that use the engine as part of the frame, and they're smooth as silk at all speeds. Not to mention the seating position is scary as fuck, I felt like I was sitting in a recliner, no way to drive a motorcycle. Sportbikes are ergonomic and what a bike should feel like, you feel like your in control, your involved in the bike, not sitting on it hoping to stay along for the ride, not to mention I've got problems with some discs in my neck, and after a few miles sitting straight up and down bouncing on my spine, I was in serious pain. Sport bikes put your weight on your feet where it should be, or if it's long ass rides, you can lay on the tank. Typical Harley, only 20 or so years behind the Jap bikes, I still don't understand the point of the Twin cam. Its not like they eliminated anything, hell all they did was add another cam, second cam gear/sprocket, extra timing chain, and double the rotating mass of the valve train. it's not like they went with DOHC or 4 valves per cylinder, they added another cam, and shortened the pushrods, whooptie. awesome, I'm glad you like it, I just don't see how someone can aspire to spend 2x the money on half the bike. HD should have been out of biz years ago, but T-shirt sales are still going strong
