I'm with you: 500 cc's to 800 or so - you can get out of your own way, some fuel economy and stuff. Bigger sometimes is simply bigger!Part of the allure of my Bonneville is the engine size. In my opinion, the 750-1000cc class is the very best part of the motorcycling world. Twins any larger than this start getting too big. The new 1500 is definitely too big (and configured wrong...) for me. My 1100cc Guzzi is an anomoly in the "over 1000 class"...its only 580 lbs dry (well, thats what they claim, anyway). Thats not so heavy, but still noticable compared to the T100.
