The YZ450F’s chassis is certainly improved for 2020 with a lighter and nimbler feel compared to the 2019 model; however, it’s still a slightly heavier-feeling bike, which is due in part to it being extremely planted and having very plush suspension. It feels heavier than the Kawasaki, Honda, KTM, and Husqvarna. It also feels wider in the radiator shroud area and midsection than the Kawasaki, KTM, Husqvarna, and Suzuki. Overall, the Yamaha works best at 104mm of sag. Raising it to approximately 100mm is a give and take; it helps make the bike feel lighter and nimbler but reduces rear wheel traction. The stance feels slightly low in the rear, but not to the point where it could be considered choppered out.
