First of all I love the bike.
I dislike the sound compared to the T100, the pistons fire every 270 degrees instead of every 360 degrees like the T100 and the older Triumphs.
I like the cruiser look, I already have an older 76 Bonneville so I have the sportier bike covered.
I have done a few 6 hour rides and have no real complaint's on the comfort. I haven't been on any multi day trip's yet [they were weekend trips to a friends house over the sierra mountains}so I can't comment on that.
If you get into tight turns at any kind of high speed you can drag your heel's on the ground. I guess if anything you can use this to guage how far over you are leaning. I've never ridden a T100 but if it's anything like my T140V The America can't compare in handling.
Low speed's are not a problem, it handles just fine.
Bonneville's don't have gobs of horse power but the 790 engine is only a half second slower in the quarter mile than the much larger Harley Sportster and the America handles much better in the turns. I can loose a Harley any day in the turns.
I ride side by side with my Harley buddies on the freeway and when passing an 18 wheeler it tracks right pass them.
I figure if it fits buy it. The first bike I sat on was the Standard Bonneville in the showroom. It was sitting next to the America and my wife said " You've already got one of those. Go try that one over there". She really liked the way it looked and I did too so that's the one she bought me.
Like I said, I love the bike.
