Taking the YZ450F to the woods

Vital Review
First Impressions: 2019 Yamaha YZ450FX

A year after releasing an all-new YZ450F motocross bike, Yamaha has taken those same updates plus some additional changes to the YZ450FX. This year we were in for an even bigger treat, as we actually got to fly back to test this new model in trees, creeks, and roots of South Carolina...giving us a feel for what this machine can do on its' home turf. Hit play below for our thoughts.

Incredible, the mapping on a phone stuff is kinda Star Treky. Had a WR450, rocket on the trails, a little zippy for tight stuff. Great bike in almost every way. Bought a new RFS motored 525EXC, thought it had a hinge in it. After macho dollars and still far from great legs we are growing old together. Although those dollars were worth it for a hydraulic clutch. Once you’ve had it....

I like what you said about being better for a large percentage of riders on MX. The guys looking for that step back from the 450 MX because they are finding a current 450 MX a bit much, but still want that down low should look here.

Thinking very hard on getting one, but in reality I think a 450 is too much in the trees! But Man they look sweet!
I really wish yamaha would make a 350,
I wouldn’t hesitate!
