Not so for Triumph. Hold the throttle in any position and shift it. Actually I’m not certain that it does work with a closed throttle position, I’ll have to try it. I just think if you are going to close the throttle you might as well clutch it too.I don’t know how the Triumph QS works but for BMW and others in general, you have to close the throttle to down shift. This allows the QS to know how much to blip the throttle to rev match.
