o6 apex, I like, smoother upshift and quicker back shift, no more wacking the throttle to get it to back shift in the corners. I got it more for trail riding,40-80mph, it really wakes it up on on & off throttle punchs in that mph range. you have to dial it in for what you like becouse Team seems to only offer 1 set-up for the secoundary and its staight line wide open, not trail.
