Suzuki Press Release: 2018 Suzuki RM-Z250 and RM Army Amateur Program

The championship-caliber 2018 Suzuki RM-Z250 has been carefully developed to deliver a high level of performance by incorporating a variety of features originally created for Suzuki’s factory race bikes. The competition-proven Suzuki Holeshot Assist Control (S-HAC) gives riders the best shot at grabbing the holeshot on a wide variety of track conditions, and the specialized KYB PSF2 Pneumatic Spring fork provides both easy adjustability and outstanding action to give the RM-Z250 more precise handling than ever. The remarkable KYB rear shock and the well-sorted aluminum twin-spar frame ensure the razor-sharp handling Suzuki’s are famous for.

Enlist in the RM ARMY and enjoy Suzuki Amateur Racing Support! Suzuki’s RM Army and Amateur Racing Support is top notch, offering over $3.8 million in contingency, trackside support, and the opportunity to train with Ricky Carmichael at Suzuki’s exclusive Camp Carmichael.

2018 RM-Z250 Features

New Features

New, competition inspired body panel colors, graphics and seat color align perfectly with the all-new RM-Z450.

Engine Features

249cc 4-stroke liquid-cooled DOHC 4-valve fuel-injected engine delivers remarkably smooth and controlled idle-to-redline performance.

The RM-Z250’s engine has heightened mid-range power and torque while maximum power is maintained. Power delivery is smoother and linear for easier control thanks to the following.

Crankshaft and magneto mass are balanced to reduce engine braking losses, while the camshafts and intake valves design widens engine performance. Slippery cam chain tensioner and precise adjuster reduce valve train friction.

Crankcase passages are designed for increased lubrication. The clutch cover with oil level window eases maintenance checks.

The compact aluminum cylinder is finished with Suzuki Composite Electrochemical Material (SCEM) coating for durability, light weight and efficient heat transfer. Specially designed piston, piston pin & rings improve durability and ring-sealing pump.

Cooling performance is efficient with balanced flow between the left and right radiators, and a high capacity coolant pump

The exhaust’s long head pipe enhances low-to-mid range power while the lightweight muffler meets AMA sound standards.

Specially designed kick drive gear, breather gear & kick idle gear ratios with an effective decompression system improves starting. Unlike some competitor’s motorcycles, a hot-start lever system is not required.

Advanced Electronics

Designed for motocross use, the lightweight, battery-less, electronic fuel injection system with progressive throttle linkage delivers efficient power. A 12-hole fuel injector sprays a fine fuel/air mist for efficient combustion while the throttle valve angle also reduces engine braking losses.

Easy-to-use Fuel Couplers are included to simplify EFI tuning.

For quick fuel adjustments to suit riding conditions, two couplers are provided. One is for rich and another for lean fuel setting compared to stock setting. Riders can change fuel settings in seconds by simply connecting either coupler to the wire harness.

Suzuki Holeshot Assist Control (S-HAC) is a selectable launch mode system derived straight from factory race bike. S-HAC helps the rider’s takeoff from the starting gate for an early lead. There are three modes riders can choose for the best option per their skill level and starting conditions.

Transmission Features

Well-designed 5-speed transmission enables precise gear shift operation. The gear selection feel and accuracy is the result of a refined shift cam and shift lever. Specialized machining processes ensure the precision of the matching gears.

Chassis Features

Slim chassis design creates a trim riding position, allowing the rider to actively take control of the machine.

Advanced design KYB PSF2 Pneumatic Spring front fork uses air chambers in place of steel springs for light weight, easy adjustability, improved damper performance and smooth action from low friction. Riders can adjust both air forks with one balanced air pressure setting from a hand-pump. Compression damping is adjustable while rebound damping force is both high- and low-speed adjustable.

Front upper and lower fork clamps are anodized black, complementing the gold fork leg finish.

Innovative KYB rear shock absorber is connected link style to the swingarm via re-shaped cushion rods and spacers. The nitrogen-charged, piggyback style shock features a new top-mounted integral adjuster system for easy adjustment of the high- and low-speed rebound, and high- and low-speed compression damping force adjusters. Spring preload can be precisely tuned via a threaded collar on the main shock body.

Lightweight front brake caliper has low mass while still providing outstanding stopping force.

Dunlop MX52 series tires are used featuring CTCS (Carcass Tension Control System) technology for superb rigidity and high level of grip.

Race-inspired waved disc rotors are mounted to black-anodized EXCEL aluminum rims with stainless steel spokes.

Aluminum fuel tank provides sound foundation and cooling for the internal EFI fuel pump. Fuel capacity is 6.5L (1.7 US gallon).

The standard Renthal Fatbar is stronger and reduces vibration more than conventional aluminum handlebars.

Champion Yellow bodywork (including new yellow rear fender) with race team-inspired graphics package.

New color gripper seat, with projected cross-shaped patterns on the yellow top surface, aids rider control.
