SUZUKI RM-Z250 2025

The 250 class in motocross doesn t forgive the slightest weakness That s why we ve designed the RM Z250 to achieve the right balance of Run Turn and Stop necessary to win in this ultra competitive arena with a powerful engine lightweight frame amp swingarm and high performance suspension This intensive work by our engineers has once again made the RM Z250 the leader out of the gate

Powerful Engine

The RM Z 8217 s 249cc 4 stroke fuel injected DOHC engine extracts maximum performance out of the RM Z250 8217 s powerplant including a large air filter intake aperture and straighter outlet to the throttle bodies for maximum airflow a cylinder head intake and exhaust ports designed to improve combustion efficiency and increase fuel pressure for enhanced fuel air atomisation a direct throttle linkage for better feel all designed to deliver the best possible power across the board

Cylinder Head and Injectors

The cylinder head intake and exhaust ports are designed for optimum combustion efficiency and increased fuel pressure for enhanced fuel air atomisation combined with intake and exhaust port tuning and crankcase design to achieve the best possible output

The RM Z250 s fuel injection system features two injectors Instead of using a single injector that can compromise low end fueling in order to supply enough fuel for top end power the primary injector delivers precise low rpm fueling while a secondary injector at higher rpm provides the extra fuel needed

Throttle Bodies

The RM Z250 benefits from the latest throttle body design with a straighter outlet for more airflow

Exhaust System

The exhaust pipe of the RM Z250 is an optimal length with the internal diameter tapering from 35mm at the cylinder head to 45mm at the silencer to ensure the best performance from the 249cc motor

Chassis

The frame and swingarm use aluminium spars changing to a hollow square section that does away with an internal rib allowing for reduced mass while increasing torsional rigidity for better stability and bump absorption

KYB Front Forks

The KYB coil spring fork features a unique design that provides a progressive damping setup offering excellent compliance over small bumps while firming up deeper into the stroke to handle bigger hits such as harsh jump landings Upper and lower triple clamp design has been optimised for rigidity while cutting excess mass

KYB Rear Shock

Out back the rear suspension linkage ratio is optimised to firm up short stroke movement while ensuring longer suspension action for better traction and minimal weight

Strong Stopping Power

All of the RM Z250 8217 s speed potential won 8217 t help if you can 8217 t keep the 8220 Stop 8221 portion of the performance triangle balanced so for the RM Z250 8217 s front brakes we use a disc diameter of 270mm and the brake pad material gives a linear response characteristics as you brake harder

Aggressive Styling

The RM Z250 maintains Suzuki 8217 s distinctive 8220 Beak DNA 8221 styling Intended to convey the brand 8217 s heritage of speed
in our off road bikes the front fender and radiator shroud are arranged to form a straight line with the sharp and edgy angles expressing a feeling of dynamic speed Like the RM Z450 the RM Z250 is finished in the Team Suzuki off road colours of yellow with blue accents making the RM Z lineup easily recognisable

Rider Technology

The RM Z250 is equipped with some of the most advanced rider technology available including our latest Suzuki Hole shot Assist Control S HAC system and latest generation traction management system

Suzuki Hole shot Assist Control S HAC

The RM Z250 s S HAC monitors throttle position and gear position in order to adjust ignition timing for maximum acceleration through the three critical stages of a motocross start the exact moment of launch getting over the starting gate and then powering up the start straight Three settings are available with A mode intended for harder surfaces where controlling wheelspin is paramount B mode for normal dirt conditions with good traction and an off setting

Traction Management System

The ECM monitors the throttle position engine speed and gear position This data is used to control ignition timing adjust the fuel injection rate and control engine output to optimise traction to help match the riding conditions as best as possible These help controllability to take the rider one step closer to winning races

Factory Racing Style

The RM Z250 has a fresh look that enhances Suzuki 8217 s already distinctive design theme The evolution starts with aggressive 8220 Beak DNA 8221 which projects a dynamic arrow form extending from the front fender through the radiator shrouds Finished in Suzuki yellow with new team graphics and logos the RM Z250 is recognisable at a glance
