Suzuki's motocross bikes received significant updates the past two years. The RM-Z450 was heavily revised in 2018 with an all-new chassis, a Showa 49mm coil-spring fork, Showa Balance Free Rear Cushion (BFRC) shock, and a few internal engine changes. In 2019, it received a lighter-rate shock spring, different damping settings for the fork and shock, and new graphics. For 2020, Suzuki's flagship motocross bike returns with new black and blue accentuated graphics. The RM-Z450 will be available in July 2019 for 8,999.
