All four models use twin 320mm front disc brakes from and four-piston calipers from Brembo, but all except the Sport model use radial-mount calipers. Brembo also supplies a 220mm disc and two-piston calipers for the rear brake.

The Sport model also has conventional Öhlins forks whereas the SF, Café Racer and SE use upside-down Öhlins forks. Öhlins also supplies reservoir-style twin shocks for all Norton Commando models.
