Engine Features
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.
Engine starting is simple and efficient due to a long kickstart lever, well-matched internal gear ratios, a large air cleaner and breather system, plus an automatic decompression system that works precisely and efficiently.
Suzuki’s advanced fuel-injection system creates extra-smooth power delivery, high fuel efficiency, and superb reliability.
This throttle body design eliminates a complex control linkage, so the rider feels a more direct connection to the engine.
Transmission Features
Thanks to Suzuki’s design and production standards, shifting the five-speed transmission is smooth and precise, while the multi-plate, wet clutch uses a lever and cam release mechanism for a light and direct feel.
The well-sorted, five-speed transmission enables precise gear shift operation. This precise transmission feel is the result of an accurately machined shift cam for exact gear selection.
Chassis Features
Balancing lightness with strength to achieve exceptional handling, the aluminum frame and beam-style swingarm support the fully adjustable Showa® Balance Free spring fork and shock that deliver remarkable damping response.
The short wheelbase and frame head pipe location produces quick and nimble handling characteristics.
Springs in each fork leg combine with large, adjustable damping cylinders to deliver better response to the terrain and provide a strong feeling of control to the rider.
The front brake uses a large 270mm, wave-style rotor with a twin piston caliper.
Electrical Features
Suzuki’s MX-Tuner 2.0 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.
Styling Features
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.
Additional Features
Suzuki Genuine Accessories include items that can enhance the RM-Z’s performance and simplify maintenance.
