2019 Honda CRF450L

Chaparral Motorsports
May 23, 2018
(Press Release)

The trails are calling, and the all-new, road-legal Honda CRF450L answers, expanding customers' off-road possibilities by enabling access to the best riding trails on public lands, even when that means connecting them via asphalt roads. Based on the CRF450R, the durable CRF450L is a full-fledged off-road machine, but with street legality achieved via features like LED lighting, mirrors, and a dedicated exhaust system, making this bike equally at home in the woods, desert, or the roads in between.

This is the bike so many have been waiting for. The one serious riders have dreamed about. A true street-legal dirtbike that offers the reliability, refinement and quality of a Honda, along with the light weight, handling, and power of our best off-road machines. Introducing the new 2019 CRF450L. Sure, you've seen dual-sport bikes before, but this is something much, much more: a true trail-to-trail machine. Developed in tandem with our all-new 2019 CRF450X, it features a powerful 449cc Unicam engine, twin-spar aluminum CRF chassis, six-speed transmission, and premium suspension. Electric start? Naturally. All-LED lighting package? Of course. Until now, you've always had to choose between performance and reliability. No longer-with the CRF450L, you get the best of both worlds. And "best" is a word you're going to hear a lot when you're talking about this bike.
