The only other revision made in 2019 was non-performance-related in the form of new graphics, and that is the only change Suzuki’s flagship motocrosser received for 2020. On our in-house dynamometer, the RM-Z450 produced 49.9 hp at 8,900 rpm and 32.4 pound-feet of torque at 7,600 rpm, putting it fifth in horsepower and fourth in torque output of the six 450cc MXers. At 251 pounds wet, it’s the heaviest bike in its class and the only one to not come with electric start. Bottom line? A good motocross bike in a segment filled with greats.
