2019 Honda CRF450X
Having featured heavily in
Honda-mounted teams winning 20 of the last 21 Baja 1000s, the
CRF450X gets a complete overhaul for 2019, injecting the DNA of
the modern CRF platform into a true off-road machine suitable for
year-round racing and trail riding. With off-road appropriate
features like a sidestand, 18-inch rear wheel, headlight, and
sealed chain, the CRF450X is ready for desert expanses or tight
woods.
Honda's CRF450X has long been the choice of Baja champions and
woods pros-and riders who want the light weight and awesome power
of a premium MX bike, but who also know that while MX machines are
perfect for 30-minute motos, out in the big, bad, open-class real
world you need a machine that can do more. That all-around
excellent performance is what's made the CRF450X always stand out,
whether it's in the winner's circle in La Paz or out on your local
trails. And for 2019, the CRF450X has been completely overhauled
from the ground up-with lots of new upgrades, including an all-new
aluminum frame and . . . wait for it . . . a six-speed
transmission!
