Interesting observation. It's pretty common to hear riders coming from American V-twins expecting the V11 to be as happy in lower revs. Yet, quite the opposite is true: the V11 just *starts* getting happy at 4,000 rpm, sweet spot: 5,000, and **SWOOSH** (right, Dave?) beyond that!
She'll cruise all day long at 4-5,000.
At 2,000 to 3,900, the V11 will be decidedly unhappy for a number of reasons.
So, let her sing that full-chested aria!
