So, when I bought the bike, I gave myself a promise not to go into Sports mode at least 5 months, or till I feel comfy in Road mode.
Even though I fully intended to learn to drive it in Rain mode, I right away had trouble with giving it enough throttle at launches. After switching to Road mode, it just clicked, stopped stalling. Thinking back, I think I had a fear of giving so much throttle travel for a bike of this engine size. Thus, the Road mode fixed the problem because in this mode the amount of throttle rotation seemed more natural for my expectations how a bike should behave.
Now, going back to the discussion of the Sports mode, I finally switched to the Sports mode today FOR THE FIRST TIME. Though, went with the Rider custom mode, where I chose the Sports mode as a map, but the reason was for ability to chose the Road setting for Traction. Knowing how my other bike is set up, the Sports mode would have a lesser traction protection. I don't want to be surprised by changed traction mode. Thus, I opted for Rider custom, to keep the same traction.
Now, what did I experience going from Road to Sports? Well, I am so happy to report that the 1st gear is so much better yet. In Road mode I HATED the 1st gear, it was noisy, way too much engine brake, too much vibration on low speed, and also, it would quickly drop to lugging, thus, required too much clutch feathering. When I rode in Road mode the 1st gear, I always felt a need to get into the 2nd to get a smoother experience, also, less engine braking.
After the switch to Sports, man, it is a different 1st gear. Finally I am enjoying riding slow. Way less engine braking. It almost self-walks itself at 10mph without dropping to self-lugging. It feels like 2nd gear. Even revving in N or with full clutch in, I think the sound is less flat. I tried 2nd and 3rd gear, feels more smooth. I am very happy that this mode made the bike so much more enjoyable. Of cause, it takes off so much faster, I need to learn now to slightly pace myself from achieving to high of a speed from a traffic light.
