2018 Suzuki RM-Z250 ELEVATING THE WINNING BALANCE. The RM-Z250 continues to deliver a higher level of performance with suspension and frame advancements to improve its already class-leading handling. With the addition of Suzuki Holeshot Assist Control (S-HAC), new KYB PSF2 front fork and extensive internal engine upgrades, the RM-Z250 is loaded with over 80 redesigned components making this the most advanced RM-Z250 yet. Features may include: ENGINE 249cc 4-stroke liquid-cooled DOHC 4-valve fuel-injected engine delivers remarkably smooth and controlled idle-to-redline performance. The compact aluminum cylinder is finished with Suzuki Composite Electrochemical Material (SCEM) coating for durability, light weight and efficient heat transfer. The piston pin now has Diamond-Like Carbon (DLC) surface treatment, for less friction and increased durability. 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. 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. TRANSMISSION Well-designed 5-speed transmission enables precise gear shift operation. The gear selection feel and accuracy is the result refined shift cam and shift lever. Specialized machining processes ensure the precision of the matching gears. CHASSIS Slim chassis design creates a trim riding position, allowing the rider to actively take control of the machine.
