Wide open throttle to redline hardly ever. I don't see a need, as fun can be had well before I reach that point. I would be flying through traffic dangerously all the time, burning through tires like crazy lol, making babies cry.
I stay on the modest side of things with mine... shift in the mid-range and maybe linger around 10-25% throttle 90 percent of the time. Love the feel of acceleration down low about as much as up high. Its loud too... so unless I want to be the center of attention in traffic... no... I'll continue to stay modest... somewhere between baby and beat, but closer to baby...
