For me, it depends on a few things. I ride to work every morning on a stretch of highway that is 55 MPH. I have about a mile to get the bike warmed up before I hit the 55 zone which is not nearly enough, even after a 3-5 miute idle after start up.
I did some testing this weekend and found that if the motor was fully warmed up (215-220 oil temp) I got the best response and fuel mileage by running around 2700-2800 RPM. However, when the motor is cold MPG went WAY down and so does performance.
I found it is better for me to try and stay around 2400-2500 until oil temps are 200 or so.
Optimal RPM will be dependent on many things....cams, engine size, compression, temperature...etc.
