Suzuki announce 2017 RM-Z machinery
By Team TMX on 9th Jul 16
Suzuki Motor Corporation have announced the 2017 RM-Z450 and RM-Z250 production motocross machinery, which have been given a slick and stylish new look.
The highly-acclaimed motorcycles, currently dominating the AMA Pro Motocross Championship in America in the hands of Ken Roczen on his RCH Suzuki Factory Racing RM-Z450, and the RM-Z250 - holding a strong second place in the World MX2 Championship with Jeremy Seewer - feature new-look graphics and black anodised rims, triple clamps and new seat colours.
Suzuki has stayed with its winning formula for 2017; utilising the data gathered from the race tracks by its global factory riders and teams.
Specifications for the 2017 RM-Z450 and RM-Z250 are:
RM-Z450 Key Features:
449cm3 4-stroke liquid-cooled DOHC 4-valve fuel-injected engine developed to deliver phenomenal idle-to-redline thrust.
Suzuki Holeshot Assist Control (S-HAC) is a selectable launch mode system derived straight from factory race bike. S-HAC helps the rider in launching from the starting gate for an early lead. S-HAC has three selectable modes so riders can choose the best option for the conditions and their skill level.
Through feedback from the factory racing teams, the piston, piston pin and connecting-rod are developed with use of Finite Element Method (FEM) analysis.
The piston pin has Diamond-Like Carbon (DLC) surface treatment for less friction and increased durability.
Lightweight, battery-less, motocross-use electronic fuel injection system with progressive throttle linkage makes for efficient power delivery.
12-hole fuel injector delivers a fine fuel/ air mist for efficient operation.
Aluminium cylinder with Suzuki Composite Electrochemical Material (SCEM) coating, built for durability, light weight and efficient heat transfer.
5-speed transmission enables precise gear shift operation.
SFF-Air is an evolution of the SFF (Separate Function Front Fork) system with no fork spring, reduced weight, increased inner tube diameter, and increased damper rod/ piston size. The SFF-AIR is made of three chambers and the rider can change the spring rate with an air pump instead of changing out the fork spring.
Slim chassis design makes for a slim riding position, opening up the cockpit to allow the rider to actively take control of the machine.
Showa piggyback-reservoir rear shock with high/ low-speed compression damping adjustment, plus rebound damping and spring preload adjustments.
The rear shock, working through Suzuki's superlative rising-rate linkage system, provides 310mm of wheel travel, delivering maximum traction. Race-inspired waved disc rotors and Excel aluminium rims are standard equipment.
Renthal Aluminium Fatbar is standard equipment. It has more strength and less vibration than Aluminium straight handlebars.
Gripper seat, with projected cross-shaped patterns on a yellow top surface to provide additional grip.
For quick fuel adjustment settings to suit riding conditions, two couplers are enclosed. One is for rich and another for lean fuel-setting compared to stock setting2. Customers can change fuel settings to best-suit the riding conditions by just connecting either coupler.
Maintenance cap for fuel pump and plug for fuel hose are enclosed for ease of maintenance when the customer removes the fuel tank for maintenance purposes.
The muffler body uses conventional bolts instead of rivets to simplify the replacement of muffler's glass wool packing.
FI indicator (optional part: 36380-28H00) has hour meter function, indicates how many hours of engine-running.
RM-Z250 Features:
The 249cm3, 4-stroke, fuel-injected, DOHC engine, with a compact and lightweight design, powers the RM-Z250's championship-winning performance.
Suzuki Holeshot Assist Control (S-HAC) is a selectable launch mode system derived straight from factory race bike. S-HAC helps the rider in launching from the starting gate for an early lead. S-HAC has two selectable modes so riders can choose the best option for the conditions and their skill level.
Through feedback from factory racing, the piston and piston pin were developed using Finite Element Method (FEM) analysis. The piston has shot-peening surface treatment for greater durability. Piston pin is now DLC (Diamond Like Carbon) coated, for less friction and greater durability. Piston ring uses a ‘L-shaped' ring. This increases sealing performance and reduces blow-by gas.
The advanced battery-less fuel-injection (FI) system features a 44mm throttle body with progressive throttle linkage and a 16-bit computer.
The fuel injection system uses a unique capacitor-assisted starting system and is powered by a durable, lightweight magneto-generator after starting.
The aluminium cylinder with Suzuki Composite Electrochemical Material (SCEM) coating is built for durability, light weight and efficient heat transfer.
The transmission design achieves a smooth yet solid shift feel. The method of fastening the sprocket attains a quick shift feel.
PSF2 front fork is KYB's latest Pneumatic Spring Fork, PSF2 is much lighter and has more adjustability than conventional coil-spring fork. Rebound damping is 2-way adjustable in high and low speed. Thanks to no-coil spring design the damper cylinder is enlarged. It results in greater damper response and more stable damper performance.
KYB rear shock features integral adjuster system. That provides easy access to adjusters, rebound damping and compression. High & Low speed is adjustable with the integral adjuster.
Excel Aluminium rims are made specifically to withstand rugged racing environments, including Supercross, Motocross and off-road conditions.
Renthal Aluminium Fatbar is standard equipment. It has more strength and less vibration than Aluminium straight handlebars.
The gripper seat has projecting cross-shaped patterns on its yellow top surface to provide additional grip.
Two couplers are included for quickly adjusting the fuel setting to suit the riding conditions. One is for a rich and another is for lean fuel settings. The customer can change the fuel setting to suit the best riding conditions by just connecting either coupler.
A maintenance cap for the fuel pump and a plug for the fuel hose are included for ease of maintenance when the customer removes the fuel tank for maintenance.
The muffler body uses conventional bolts in the end cap instead of rivets to simplify the replacement of the glass wool packing in the muffler.
FI indicator (optional part: 36380-28H00) has an hour meter function, and indicates how many hours the engine has been running.
