Once Kawasaki released the GPZ550 (ok, I'm old), I was hooked on sportbikes and rode nothing but sportbikes for the next 25 years. I couldn't figure out the Harley thing because I didn't think it took any skill to ride one. Our department went to Harleys and I was depressed until I started riding them. big? Yes. Heavy? You bet. Performance? Are you kidding?
What I learned was that it takes even more skill to ride an Electraglide fast or tight because unlike a sportbike, any deficiencies in your riding will be magnified 10x over. After riding the HD for a couple of years, my skill level actually increased on the police ST as well as my sportbikes and my dirtbikes. I also realized that there are times when I just don't feel like getting suited up and hopping on a GSXR,ZX,CBR,R1/6. Maybe it's age, but lets face it, all of us will get old someday.
It's nice to just jump on a simple bike like a XR1200 and stop for a quick bite to eat or hanging out with some friends (the non riding ones anyway).
