On the fueling front, I much preferred the Shiver in the Tour throttle map. Sport was just a shade too sporty, and Rain is ultra gentle but cuts power by about 30 percent (can't have that, unless it's actually raining). Tour is the best balance, plus it suits the Shiver's personality. This isn't a rowdy naked bike that wants to wheelie off every corner. It's strong, but also mellow and dignified. Throttle maps are the last remnant of Aprilia weirdness in the switchgear, incidentally—everything else is controlled by the toggle on the left bar, but switching modes means tapping the starter button while the bike is running.
