Many V-twin designs make most of their torque at relatively low RPMs and peter out soon after, and most of the cruiser market expects that. A lot of us (myself included) had to get used to the idea that 3K was the beginning of the fun zone on the ST rather than the end. Retune for that and something else has to give.
+1 All of my bikes have been Hondas except for a Duc 750 Sport. It has always seemed that cruising speed (what ever that was on any Honda) was 4000-4100rpm. That was always a little buzzy even on my GL-77. Maybe a taste lower on my V65 Sabre because of the sixth gear but I don't remember exactly.
What a change when I got my Duc. Low end torque was a whole new experience to me. And cruising? I thinking that it was >3000rpm. It could get quick in almost any gear just with roll on throttle. Red line may have been about 7K and I seldom saw it even in first gear. It got pretty fast at low rpm. And about cruising: the low rpm gave a very relaxed feeling like I had all day to get where ever I was going. Like the bike was telling me "The sooner we get there the sooner the ride is over. Just so ya know". It went as fast as I wanted to go and went when I wanted to. But it never felt like it was pulling at the traces. My V65 was my only Honda that came close to that relaxed feeling.
