Conclusion
The 2019 Yamaha YZ450F isn't radically changed
from last year's model, but the refinements make
surprising improvements, and in all the right
places. Sometimes it's not about going back to
the drawing board but tweaking and fine-tuning
the bike you have. Props to the Yamaha R&D team
for developing and pushing this bike to make it the
best version to date. CN
