First rides & tests

BMW's new HP4 is the first production motorcycle to feature semi-active suspension - its damping constantly changes as you ride.
It's also a massive 9kg lighter than an equivalent S1000RR and has an even more refined traction control system, which can now be adjusted on the move.
To find out what makes it tick, we rode the HP4 Carbon at the Jerez MotoGP circuit in Spain.
