Details have emerged on how the Bimota KB998 Rimini's active winglet system operates. Instead of hydraulics, it uses an electric motor with a cable-driven mechanism, moving the blades through 15 degrees in 0.5 seconds. It runs independently of the IMU, using only road speed, brake pressure and throttle position, engaging from 160 km/h and going fully flat above 200 km/h, with a fail-safe that defaults to maximum downforce.

Looking at the numbers, this active winglet is more interesting than the spec sheet lets on. Only 15 degrees of travel, but it folds flat in 0.5 seconds, and it runs purely on road speed, brake pressure and throttle input — no IMU needed. Compared to fixed winglets on older models, the whole design philosophy is different. This is the good part.

Kicks in from 160km/h, so this is a feature you'd never use on public roads.

Still, just knowing it exists is hype enough for me.

Movable winglets were sci-fi a few years back, now they're on production bikes.

Compared to Ducati or Aprilia's hydraulic setups, electric plus cable seems aimed at saving weight.

Moving 15 degrees in 0.5 seconds, honestly doubt it works that cleanly in real racing.

If the fail-safe defaults to max downforce, worst case it still errs on the safe side.

Controlling it with just speed, brake pressure, and throttle instead of an IMU is a bold simplification.
