CRF450RX
Enduro racing is an ever-changing challenge—the terrain, the competition, the weather, the course. And you can’t be static in a changing environment if you want to prevail. That’s why we’ve given the class-leading Honda CRF450RX so many big changes this year. Basically, it gets all the same awesome upgrades as our CRF450R: new frame, cylinder head, hydraulic clutch, clutch internals, fuel injection, single-muffler exhaust, and more. Plus we’ve fine-tuned the suspension specifically for enduro riders, shaved approximately four pounds off last year’s bike, and even hooked you up with factory hand-guards. All in all, it’s the highest performing bike we’ve ever offered in the class. Embrace the changes—then embrace victory.
