Take it to the redline. These engines torque out pretty linear and any slight dropoff in the last say 500 rpm is made up by being 500 rpm higher in your next gear.
These engine rev so well. I drove Hondas before and they are supposed to rev as their specialty, but somehow they always feel like they are holding back and working too hard near redline. (Hard to describe, but maybe you know what I mean) The Boxer just feels normal at all speeds, makes those great sewing-machine sounds.
