Delivering excellent throttle response through the entire rev range, the 449cc, liquid-cooled, four-stroke, four-valve, DOHC engine is the latest incarnation of Suzuki’s proven fuel-injected powerplant that delivers high peak horsepower with strong torque characteristics.

Adjustments to the cylinder head’s intake port shape and finish were revised for 2027 to match intake camshaft and exhaust changes. The port shape funnels the fuel/air charge into the combustion chamber to help boost engine output.

Suzuki’s advanced fuel-injection system creates extra-smooth power delivery, high fuel efficiency, and superb reliability.

The throttle body design eliminates a complex control linkage, so the rider feels a more direct connection to the engine.

The well-sorted, five-speed transmission enables accurate gear shift operation. This precise transmission feel is the result of a well-machined shift cam for exact gear selection. Specialized machining processes also increase the precision of the matching gears.

The multi-plate, wet clutch uses a lever and cam release mechanism for precise feel of the engagement and disengagement points while riding.

The new KYB®-supplied coil spring fork has large diameter inner tubes and sturdy internal components for strength, durability, and good damping force control.

The short wheelbase and frame head pipe location produces quick and nimble handling characteristics.

New, lightweight, and strong RK Excel rims are used on the RM-Z450 wheel set, contributing to good chassis compliance and feedback to the rider. The bike is fitted with racetrack-developed Bridgestone® Battlecross X30 tires.

The strong RENTHALL-supplied aluminum tapered handlebar has a straighter bend compared to prior models to help the rider maneuver the motorcycle.

Suzuki’s MX-Tuner 4.0 is included and provides the ability to adjust the fuel injection and ignition settings though a smartphone application, while the Suzuki Holeshot Assist Control (S-HAC) and advanced traction management system provides the rider a performance edge.

The Suzuki Holeshot Assist Control (S-HAC) is a selectable launch system derived from the factory race bike to help riders’ takeoff from the starting gate for an early lead.

Suzuki’s proven; easy-to-use fuel couplers are also included to simplify EFI tuning. Riders can change fuel settings in seconds by simply connecting either coupler to the wire harness.

The RM-Z450 features an evolved and efficient traction management system. The Electronic Control Module (ECM) continually measures throttle opening, engine speed, and gear position and then adjusts the ignition timing and fuel injector duration to fine-tune the engine output to help deliver the best traction for the riding conditions.

The Suzuki beak-inspired styling has sharp front fender and radiator shroud shapes that blend into the frame’s side covers and into an upswept tail.

This functional styling and trim chassis permit a variety of rider positions that facilitate maneuvering and comfort.

Made with a special density foam, the seat is well shaped and slim to help the rider maneuver the motorcycle. The seat has a large blue gripper panel that runs nose-to-tail on the cover.

The seat base, inner fenders, and side covers were developed to reduce the amount of moisture and dirt reaching the air cleaner. This helps prevent debris from contaminating the air filter element.

Suzuki Genuine Accessories include items that can enhance the RM-Z’s performance and simplify maintenance. See Suzuki’s industry leading contingency programs at www.SuzukiCycles.com/Racing.
