What is a good example of a modern mid size V-Twin? I have only tried the Ducati's, and they just didn't do it for me. My understanding is that most Ducati cylinders are over-squared so the power comes a bit later. In my experience, they were very lumpy below 6k. After that they performed very good, but with a limit of ~11k the RPM band is too narrow for me. I have tried the Ducatis (848, 937, 959) while owning a Street Triple and the S1000RR, which both have very broad and useful RPM ranges so the differences were very pronounced. I have heard many people say how they love the immediate torque of the twins, but I cannot say I see that in the Ducs.
If I were to buy a V-Twin for track, is there a current offering? Excluding the KTM 1290, which is too much for me.
