I have made the same change as Richard, and it certainly makes a difference, but as to quicker , I think that will depend on the course. If there is a really tight course, and a number of sprint courses have hairpins around a single bollard, then the lower ratio in second gear is a hugh bonus. But as Richard says there is the potential for more grear changes, sometimes, when you really could do with out it. Suppose that would be why race cars/ bikes change ratios to suit the individual track 😬
