Forbidden Dreadnought 3 MX - KX500

Forbidden Dreadnought 3 MX – Push Harder. Fear Nothing.

The Forbidden Dreadnought 3 MX isn’t here to mess around—it’s here to dominate. With a mixed-wheel setup (29” front, 27.5” rear), 160mm of rear travel, and dual crown compatibility, this beast blurs the line between enduro and full-blown downhill. Version 3 takes everything that made the original a monster and dials it up: smarter suspension, sharper geometry, tougher hardware, and more customizability than ever.

Powered by Forbidden’s refined Trifecta V2 high pivot suspension and loaded with next-gen SRAM Transmission components, the Dreadnought V3 MX is as relentless as its name suggests. Whether you're charging blind down alpine singletrack, floating over tech, or slamming berms in the bike park, this machine stays composed, aggressive, and ready for whatever lies ahead.
