DU­CATI’S SKYHOOK SUS­PEN­SION

Motorcycle News (UK) - - THIS WEEK -

Du­cati Skyhook Sus­pen­sion (DSS) is a semi-ac­tive sus­pen­sion sys­tem that can be found on the firm’s Mul­tistrada mod­els. Launched in 2013, the set-up works by cre­at­ing an imag­i­nary point above the bike, and then uses ver­ti­cal ac­celerom­e­ters, on the triple-clamps and sub­frame, to cal­cu­late the sprung data, and sen­sors on a fork leg and the lower swingarm to cal­cu­late the un­sprung data. The imag­i­nary point can be thought of as a hook that is sus­pend­ing the bike in the sky from its front and back wheels, and the data that’s gath­ered from the sen­sors is fed into an al­go­rithm that al­ters the sus­pen­sion’s com­pres­sion and re­bound damp­ing ev­ery 10 mil­lisec­onds. This keeps the bike at the op­ti­mum level for a smooth ride. In essence the sys­tem au­to­mat­i­cally, and very rapidly, bal­ances the for­wards and back­wards pitch of the ma­chine through the sus­pen­sion’s damp­ing to give the bike more com­po­sure. The later, post-2015, DSS Evo sys­tem also in­cor­po­rates pitch an­gle data from the IMU into the cal­cu­la­tions. Ac­cord­ing to Du­cati, the Skyhook name comes from the fact that the bike feels like it’s hooked from the sky and im­mune to bumpy ter­rain…
