The Kawasaki KX450 received a total overhaul last year and the 2020 bike enjoyed a ton of accolades from our test riders, as well as from other media outlets and consumers, too. In the very capable hands of Eli Tomac, the KX450 earned the Monster Energy Supercross Championship, and there's little doubt that the big green machine is one potent race weapon, right off the dealership showroom floor. They say if something isn't broke don't fix it, and that's exactly what Kawasaki did for 2021. Kawasaki made three important changes to the bike, and the result is a machine that is - in our opinion - without a weakness.
