Aprilia developed its own electronic engine management package for the Cube, housed in the ultra-compact ECU incorporated in the back of the instrument panel. It controls not only the ignition and Aprilia's proprietary fuel injection, but also the F1-type ride-by-wire electronic throttle control. "We have the option whether to activate this or not," says Witteveen, "but after a lot of work understanding how to map it, we now have almost a 1:1 real-time operation, which gives the rider a better sense of immediacy and throttle response, but also allows us to take out power when we want to do that." As in traction control? "Yes, we can program that in, also launch control off the line if we want to. The key to being able to do this was to get the ride-by-wire right, and we're getting very close with it, now."
