Just as 125s do, other bikes lacking in acceleration must resort to corner speed. Freddie Spencer did so naturally in 1982–83 to compensate for his Honda NS500 triple’s horsepower deficit. Ducati Superbikes, long lacking midrange essential for acceleration, relied for a time on corner speed. In 1997, Honda produced a two-stroke 500cc V-twin as a privateer GP bike, and with 30 hp less than factory V-4s, its only hope was high corner speed. In practice, the corner-speed line it required crossed the lines of point-and-shoot bikes, and its corner speed lasted only until its tires “went off” (today, riders call this “dropping”). In 2000, Mick Doohan noted that, on the Michelins of that time, corner speed gave faster lap times as long as edge grip lasted. But when tire fatigue set in, a rider had to revert to point and shoot because it is safer (less time at high lean angle) and less dependent on edge grip.
