This is my first bike with a quick-shifter and I'm slowly getting used to it. So far I like using it under full throttle but downshifting is a little odd. I keep grabbing for the clutch and prefer to use the clutch when downshifting multiple gears. Got to retrain my brain. I was reading the service manual and was surprised to learn the difference in the modes was effort and travel required to shift gears. Most of the literature just says sport and city or touring mode. I keep it in city riding mode 2 all of the time and am surprised it does not default to that mode. I guess the sport mode is to ensure there are no accidental shifts on the track because it takes a stronger motion to change gears. I'm kind of curious how they control effort and throw of the shifter though. Maybe an electronic adjustment in the shift sensor itself that delays the ignition/throttle cut. I think doing so would be harder on the transmission though.
Just a few thoughts
