2025 RM-Z250

2025 RM-Z250 Overview

With a versatile engine and responsive chassis, the 2025 RM-Z250 remains the choice of professionals and privateers everywhere. Fed by a dual injector EFI system the RM-Z250’s four-stroke, four-valve engine delivers strong, usable power through the entire rev range.

Tuning the fuel injection and ignition for maximum performance is easy and quick thanks to Suzuki’s smartphone-based MX-Tuner 2.0, and proven fuel-coupler system. The RM-Z250 continues its reputation as the best-handling 250 through a twin-spar aluminum frame and hydro-formed swingarm that carry a KYB®...

Superb performance starts with a center-port head as the fuel-injected, 249cc liquid-cooled, four-stroke, four-valve, DOHC engine is proven and dependable while delivering strong peak power and superb throttle response through the entire rev range.

The fuel injection system has extra-smooth power delivery, high fuel efficiency, superb reliability, and easy tuning capability.

Two fuel injectors are used to deliver an ample fuel-air charge for excellent combustion chamber efficiency at all engine speeds.

The high-flow exhaust system has a long head-pipe, tapered mid-section, and multi-layer silencer with good flow through the entire rev range, with an emphasis on low-rpm performance.

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

Agile handling comes from an aluminum frame that is lighter but has a ten percent increase in torsional rigidity as compared to the prior generation frame, achieving superior front-and-rear weight distribution. The KYB® coil spring fork and rear shock have fully adjustable damping force for superior suspension response.

The KYB®-supplied shock absorber has a thin-wire spring, spring guide, cushion rubber guide, and lower link that are lightweight and have better movement reaction. The spring and link weigh a pound (447.5 grams) less than the prior generation’s parts.

This KYB® shock has specialized damping force circuits and a refined rear lever ratio to help improve the suspension’s traction characteristics.

To match the handling potential of the RM-Z250, the wheels are fitted with the race- developed Dunlop® GEOMAX MX33 tires.

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.

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-Z250 features an advanced traction management system that reacts quickly to engine speed changes. 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 Holeshot Assist Control (S-HAC) is a selectable launch system derived from the Suzuki factory race bike to help riders’ takeoff from the starting gate for an early lead.

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.

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

The slim seat has a specialized foam density to increase rider comfort. The seat has a large gripper panel that runs nose-to-tail on the cover.

Suzuki Genuine Accessories include items that can enhance the RM-Z’s performance and simplify maintenance. Learn more on Suzuki’s industry leading contingency and track-side support programs at SuzukiCycles.com/Racing.
