The CTX700 is modeled as a cruiser. That means the Drive mode wants to put you somewhere around 2,500 RPM for the speed you're at. That is a design choice opposite my riding style. I find the machine has me in 5th gear at 35 mph if I've been there for a few. This also means I have virtually no torque available and at least 2 downshifts before I can accel with any authority. There is a market for that I guess. My better half really liked the "tame response" of the thing as she was learning to ride it. Before the CTX she was pillion queen on our FJR. She refused to ride back there after a suspension upgrade made it painful to do so. That bike is quite stiff now (rear spring rate is 1,000 lbf/inch!). It's a hoot to ride hard but no fun on the back seat for long rides.Yes, a Sport Mode would respond quicker if: i) You are already in a Sport Mode, and ii) You don't hit the horn or upshift button first.
The CTX is the first and only motorcycle she has ever ridden. She was insistent on a DCT because she didn't like all the clutch and foot work of a manual. Today, she does everything in Sport mode because Drive is just way too slow to respond. It's been fun and a bit scary to watch her grow into this bike.
