The new 2018 RM-Z450 model with Holeshot Assist Control and Air Forks. Developed with Suzuki Factory Motocross teams, they're set to launch race wins and careers, time and time again! The 449cc, 4-stroke, fuel-injected, DOHC engine, with a compact and lightweight design, packs the right combination of dirt-slinging torque and arm-stretching horsepower, which powers the RM-Z450's championship-winning performance.The steering head pipe design of the RM-Z450 mirrors that of the RM-Z250. This along with the rib structure on the inside of the pivot parts and lower connection mean frame weight is minimised and chassis rigidity is optimised. All this culminates in the trademark great cornering performance of the RM-Z. A selectable launch mode system derived straight from factory race bikes. S-HAC helps riders in launching from the starting gate for an early lead.
