Regarding handling, the RM-Z250 has always been the gold standard. The Z250’s RM engine, with its dual injector EFI, center-port cylinder head, and AMA-legal exhaust, produces robust and usable power over the whole rpm range.

KYB provides the suspension, which consists of a coil spring fork and an adjustable shock with four different settings for the damping force. These components are attached to an aluminum twin-spar frame and a hydro-formed swing arm. The RM-Z250 slices through the track while the rider remains in command, owing to solid brakes and a body optimized for comfort and control.

To fine-tune the fuel injection and ignition for peak performance, you only need Suzuki’s smartphone-based MX-Tuner and proven fuel-coupler technology. The 2022 Suzuki RM-Z250 continues the brand’s tradition of excellent cornering performance, thanks to Suzuki’s Winning Balance.

2022 RM-Z250 Suzuki Motocross – Features and Specs

Engine Features

Even though it has a center-port cylinder head, the fuel-injected, liquid-cooled, 249cc, four-stroke, four-valve, double overhead cam (DOHC) engine is still a popular and reliable option.

The engine has strong peak power and excellent throttle response over the whole rpm range.

To improve engine performance, the intake ports in the cylinder head have been meticulously machined to the perfect shape and quality.

The air cleaner’s output tube is routed directly into the throttle body, and the air cleaner’s aperture is more significant to accommodate a greater air flow rate.

The power delivered by the fuel injection system is very smooth, saves gasoline, is highly dependable, and is easy to fine-tune.

The combustion chamber efficiency and high-rpm power are both greatly improved by the use of dual fuel injectors. It was the RM-first Z250’s time using them.

The primary fuel injector, situated at the base of the throttle body, sprays gasoline at the butterfly valve, ensuring a finely atomized mixture of fuel and air. The secondary injector is located in the air cleaner input duct to provide for further mixing and cooling of the power and air before it reaches the engine.

To provide remarkable throttle responsiveness, the RM-Z250 uses a high-capacity fuel pump to power the innovative twin-injector system and combine the fuel and air charge.

The unusual throttle body layout eliminates the need for a complex control linkage, allowing the rider to feel more in tune with the motor.

The intake camshaft profile features more valve lift than the previous-generation RM-Z250, which results in more power throughout the RPM range.

The cam chain tension adjustment and guide are meant to minimize mechanical loss and friction.

The lightweight aluminum cylinder is coated with Suzuki Composite Electrochemical Material (SCEM) for improved durability, reduced weight, and enhanced heat transfer efficiency.

The overall machining process at the piston pin holes was modified to reduce stress at the piston crown and improve reliability.

A dependable Kickstarter and an accurately and efficiently operating automatic decompression system make engine starting a breeze.

With its bigger head-pipe, tapered mid-section, and multi-layer silencer, the high-flow exhaust system prioritizes low-rpm performance.

Despite its increased performance, the four-layer silencer still meets AMA noise regulations.

Advanced Electronic Features

The 2022 Suzuki RM-Z250 comes standard with the company’s MX-Tuner 2.0, a device that allows for simple tuning of the bike’s fuel injection and ignition systems for increased racing prowess.

Remotely connecting the MX-small Tuner’s transmitter to a smartphone app allows for speedy adjustments like ignition timing and fuel delivery.

– The MX-Tuner software may pre-program individualized parameters into the ECM when one of the included fuel couplers is attached.

– It is simple to adjust the settings of a racer or tuner to account for performance improvements.

User preferences for tracks and climates may be saved and shared with competitors.

You may monitor your bike’s health in real time by checking the engine’s data and the bike’s runtime.

Suzuki’s tried-and-true, user-friendly gasoline couplers are included to facilitate EFI tuning.

– For fast fuel adjustments to suit better riding conditions, two couplers are given. A fuel setting that is either richer or leaner than the default is the one in question. Any coupler may be plugged into the wire harness to provide riders rapid access to the gasoline controls.

The RM-Z250 now has an enhanced traction control system that better reacts to varying RPMs. Throttle position, engine speed, and gear selection are all factors that the Electronic Control Module (ECM) constantly evaluates. The ECM then adjusts the engine’s power by adjusting the ignition timing and fuel injector length to provide the best possible traction for the rider’s current conditions.

– The RM-traction Z250’s management technology is distinct from that of street motorcycles’ traction control in that it does not consider rear-wheel spin. Since moto crossers’ needs differ from street bikers, this technology enables constant modification to achieve optimal traction at all times.

The new Suzuki Holeshot Assist Control (S-HAC) is a launch system adapted from the factory racing bike that helps riders get a head start.

– The S-HAC technology has three power adjustment phases that may assist riders in getting a head start at the start: the initial push off the starting line, the crossing of the starting line, and the acceleration to peak speed.

Based on their current situation and riding ability, riders may choose one of three S-HAC configurations.

Mode A: For slick weather or rough terrain near the starting line. With this setting, S-HAC adjusts the ignition timing to prevent tire sliding during liftoff and keep the ride over the gate as smooth as possible. Ignition timing is also accelerated during this time for increased thrust. When you enter the fourth gear or wait six seconds, the device turns off, and the expected ignition timing is re-established.

If you are just learning to ride, or if the surface you’re starting on is very rough and slippery, you should begin in Mode A, which will give you more of a controlled launch.

If you want a more powerful launch, Mode B is for you. This mode activates when you have better traction at the beginning of the race. With S-HAC, the ignition timing may be advanced for more excellent acceleration off the line and quicker throttle response. Ignition timing alternation follows the same pattern as Mode A, although for a longer total duration. If the following three things occur (in that order), the ignition will return to regular operation: When you get into fourth gear or wait six seconds, the device turns off and expects ignition timing is re-established.

Mode B’s benefit is that it allows for faster acceleration off the line, which is useful when riding alongside seasoned riders or under ideal starting conditions.

Start using the default power setting (base mode), and no need to flip the S-HAC switch.

Transmission Features

Exceptional acceleration and top speed are achieved by combining the engine’s increased power and the five-speed gearbox’s second-gear and final ratio.

As one would expect from a Suzuki transmission, the shifts are silky and precise. The shift cam and gears linked with it need to be precisely machined to make up a reliable gearbox for a racer.

The multi-plate wet clutch relies on the rack-and-pinion release mechanism to give the rider an accurate feel for the clutch’s engagement and disengagement points.

The driving chain will glide along the tiny chain guide with pinpoint accuracy.

Chassis Features

The RM-Z250 continues Suzuki’s heritage of producing the best-handling motocross motorcycles with its frame and swing arm design.

For optimal front-to-rear weight distribution, the twin-spar aluminum alloy frame strikes a happy medium between the two.

The frame of the 2022 RM-Z250 is 10% more torsionally rigid than the previous generation, yet it is 370 grams (0.8 pounds) lighter.

For improved responsiveness in turns, the crankshaft has been moved upward in the frame.

The back and top engine mounts are placed externally, away from the cylinder head, to increase rigidity and give a straight intake channel to the engine.

The steel engine mount has been replaced with an aluminum one for reduced weight.

The swingarm is made using cutting-edge hydroforming technology, which allows for a lightweight but sturdy design (270 grams).

Hydroforming allowed engineers to create tapered swingarm beams with increased rigidity and reduced reliance on labor-intensive welding during assembly.

To cut down on weight, make the sub-frame seem cleaner, and facilitate the replacement of the air filter, hexagonal aluminum rails are used.

To accommodate the giant air cleaner and to streamline the bodywork, the sub-frame rails are raised and moved inside.

With the revolutionary design of the sub-thin frame and the overall slimness of the bodywork, the rider has enough room to move about in the cockpit, even during active riding.

The KYB-supplied shock absorber is light and sensitive to motion thanks to its bottom link, cushion rubber guide, thin-wire spring, and spring guide. The weight savings between the new spring and connection and the ones from the previous model amount to one pound (447.5 grams).

The KYB shock’s unique damping force circuits and enhanced rear lever ratio increase the suspension’s traction.

As a result of the wide range of adjustments available for the damping force adjusters, the settings may be better suited to the conditions and the rider’s style.

High-performance KYB coil spring front fork includes legs that use the same springs and damping force components, making it much easier to set up and maintain the front suspension.

This fork’s free-piston design, which separates the oil from the air, allows for superior damping properties. The method also aids in controlling the pressure and spring recoil of the damping cartridge, ensuring a fluid and precise fork movement.

The brand new Renthal aluminum tapered handlebar has a flatter bend and less pull-back than its predecessors, allowing the rider greater precision and stability even in the face of extreme maneuvers.

The lightweight and durable top fork bracket pair well with the grips and front suspension.

For better-stopping power and feel, the front brakes use a 270mm wave-style rotor and a Nissin two-piston caliper.

The RM-brake Z250’s pad material was developed specifically to improve its functionality. The force applied by the rider is transmitted to the lever with more efficiency using the push rod design of the master cylinder.

The rear brake master cylinder is mounted flush to the frame beam to eliminate any space between them and the potential for contamination from dirt or accidental touch with the rider’s boot.

An all-new D.I.D Dirt Star rims with a black anodized finish are used for the wheels, and their unique cross-section shape helps to maintain strength while reducing unsprung weight.

Dunlop Geomax MX33 tires, designed on the track to complement the RM-performance, Z250’s are mounted on the rims. On top of that, the new RM-rear Z250’s tire is almost half a pound (160 kg) lighter than the tire on the old model.

The upswept rear end and sharply angled front fenders and radiator shrouds inspired by the Suzuki beak are designed to provide the impression of speed while cutting down on weight and simplifying maintenance.

The motorcycle’s small frame and functional design provide various ergonomic and manageable seating options.

Changes to the RM-ergonomics Z250s for 2022 improve the rider’s ability to exert firm control over the bike in competition. The foot pegs are raised and shifted forward by 0.2 inches (5.2 mm), while the handlebar grip position is moved forward and down by 0.3 inches (7.4 mm).

The fuel tank has been updated from metal to plastic, saving half a pound. A total of 1.66 US gallons of gasoline may be carried.

The seat base, the inner fenders, and the side covers were developed to prevent dust and grime from accumulating in the air cleaner. Having less garbage floating about means less chance of clogging the air filter.

The thinner seat is made with specialized foam density to aid the rider in keeping control of the motorbike. A large gripper panel stretches from front to back over the seat’s cover.
