Suzuki made huge changes to its flagship RM-Z450 model in 2018. For 2020 Suzuki made only cosmetic color changes to the graphics of bike. Just like in 2019, the 2020 model has Showa suspension components. Up front, the new-generation Showa coil-spring fork has larger inner tubes and rod pipes.

Suzuki upgraded the entire intake system. The air cleaner opening is 30-percent larger, and the intake boot features a more direct design for increased air flow into the throttle body. The 2020 RM-Z450 returns with a unique throttle body design used only by Suzuki that has a fuel injector located on the bottom.

Suzuki’s Holeshot Assist Control (S-HAC), commonly referred to as “launch control,” returns on the RM-Z450.
