Suzuki lifted the covers off the 2018 RM-Z250 lites motocrosser and RMX450Z over the weekend but unfortunately for Australian Suzuki fans, the 450cc enduro model won't be heading down under.
2018 RM-Z250
The 2018 RM-Z250 has not been subject to the same upgrades as the flagship RM-Z450 and instead features bold new graphics for 2018.
According to Suzuki, 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. The compact aluminium 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-sealingpump
The exhaust’s long head pipe enhances low-to-mid range power while the lightweight muffler meets AMA sound standards. Cooling performance is efficient with balanced flow between the left and right radiators, and a high capacity coolant pump.
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.
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.
2018 RMX450Z
The 2018 RMX450Z is largely unchanged from previous years and although it shares components with the RM-Z it is not based off the recently revealed 2018 RM-Z450.
Features:
New for 2018, the racing-inspired bodywork and graphics includes a sturdy steering stem that is anodized black, complementing the gold fork leg finish.
Fuel-injected engine is based on Suzuki’s winning open-class motocrosser; the RM-Z450.
Trail-ready features include an electric starter powered by a compact battery (plus kick-start back-up), a coolant reservoir tank and an engine protector plate.
Aluminum-alloy twin-spar frame with high-performance SHOWA fork and piggyback-reservoir style rear shock.
