The last in our series of blogs explaining the mysteries of MotoGP electronic rider aids
OK, enough with the sniggers. This isn’t a clever computer program that helps exasperated MotoGP engineers deal with petulant, prima-donna riders, it’s an important rider aid that’s become even more so since the advent of unified software.
Anti-jerk helps riders get through the transition from off-throttle to on-throttle in the middle of a corner. As they enter the corner they have the throttle fully closed, then when the right moment comes they start to ease the throttle open. At this point the engine goes through a transition from negative torque to positive torque, which causes tolerances in the transmission to deliver a jerk (or hit) in the engine. With so much lean angle and so much torque available, this can disastrous, either ruining the rider’s drive off the turn or triggering a slide from which he or she won’t recover.
