SUZUKI ANNOUNCES 2014 RM-Z MODELS
For 2014, the Suzuki RM-Z450 and RM-Z250 feature updated ECM ignition programs that improve starting, as well as race-inspired Champion Yellow-and-black graphics to best fit each bike’s high-performance character. These upgrades show Suzuki’s continued commitment to the already-strong performance of its RM-Z450 and RM-Z250, facts proven in part by Cycle World magazine’s repeat acknowledgement of the RM-Z450 as Best Motocrosser in 2011 and 2012. And in 2013, both the RM-Z450 and RM-Z250 was chosen by Transworld MX as their bikes of the year. The RM-Z450 was also selected as the class-leader by RacerX.
“By delivering these refinements for 2014, the Suzuki RM-Z450 and RM-Z250 will continue to lead their classes,” said Derek Schoeberle, Product Media Relations Manager for SMAI. “These products are proof that manufacturing and selling category-leading motorcycles takes more than just one year. A combination of superior development, proven craftsmanship, and ongoing owner support helps Suzuki, its dealers and its riders earn multiple championships.”
The 2014 RM-Z450 and RM-Z250 retain the “Champion Approved” features and performance that have lead racers nationwide to select yellow motorcycles as their racing equipment. For years, top racers have chosen to ride Suzuki, including Yoshimura Suzuki rider James Stewart and Ricky Carmichael, whose RCH Racing team competes on Suzuki RM-Zs.
With endorsements like that, Suzuki proves that choosing an RM-Z is the best decision a racer can make. Amateur and pro racers nationwide are increasingly opting for Suzuki RM-Z motorcycles; both the RM-Z450 and RM-Z250 continue to increase their share of race entries each of the last four years. Suzuki Motor of America, Inc. will soon announce its detailed race-support offerings for the coming season.
Suzuki pioneered MX fuel-injection with the 2008 RM-Z450, and it quickly became the first fuel-injected motorcycle to win the AMA SX Championship. Suzuki motocross bikes are renowned for superior on-track handling, as well as the company’s industry-leading race support. By offering more contingency-reward money than any other manufacturer, and giving racers bikes that help them win, Suzuki will remain the right choice for motocross racers, whether that’s Ricky Carmichael or the young rider who is striving to be the best.
The 2014 RM-Z450 and RM-Z250 are expected to begin arrive in dealership in July.

2014 Suzuki RM-Z450
ECM ignition program has been changed for improved starting performance.
Stylish two-tone radiator shrouds with new aggressive graphics and yellow number plate accentuate the RM-Z450’s agile looks.
The piston pin has Diamond-Like Carbon (DLC) surface treatment, for less friction and increased durability.
Intake cam timing and amount of lift has been modified for smoother power delivery and control.
Aluminum cylinder with Suzuki Composite Electrochemical Material (SCEM) coating, built for durability, light weight and efficient heat transfer.
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.
Redesigned muffler internal parts, bottom-to-mid range power and torque are increased, resulting in improved performance without losing top end. The new muffler body now uses conventional bolts in end cap instead of rivets to simplify the replacement of the glass wool packing in the muffler.
The muffler body uses conventional bolts, instead of rivets to simplify the replacement of muffler’s glass wool packing.
For quick fuel adjustment setting to suit riding condition, two couplers are enclosed. One is for rich and another for lean fuel setting compared to stock setting. Riders can change fuel setting to best suit the riding conditions by simply connecting either coupler.
449cm3 4-stroke liquid-cooled DOHC 4-valve fuel-injected engine developed to deliver phenomenal idle-to-redline performance.
Through feedback from factory racing, the piston, piston pin and connecting-rod are developed with the use of Finite Element Method (FEM) analysis.
The newly designed piston, piston pin and connecting rod are developed with use of Finite Element Method (FEM) analysis. The new piston is 13 percent lighter without any compromise to strength and rigidity.
5-speed transmission enables precise gear shift operation.
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 2 inches of wheel travel, delivering maximum traction.
Front fork spring pre-load is adjustable, allowing a wider range of settings.
Renthal Aluminum Fatbar is standard equipment. It has more strength and less vibration than Aluminum straight handlebars.
Race-inspired waved disc rotors and Excel aluminum rims are standard equipment.
Gripper seat, with projected cross-shaped patterns on red-colored top surface to provide additional grip.
Riders can now track engine-operating time and better manage maintenance intervals using the optional FI indicator (Part no. 36380-28H00).
Latest version of Separate Function front Fork (SFF-type2) from Showa, separating the spring and damping tasks. The right leg contains the spring, while the left leg incorporates the cartridge assembly to manage damping. It results in reduced friction, increased absorption performance and weight saving.

2014 Suzuki RM-Z250
1. Through feedback from factory racing, the piston and piston pin were developed using Finite Element Method (FEM) analysis. The new piston is 3% lighter without any compromise to strength or rigidity.
2. The internal shape of the passage in the crank pin was changed to capture the sludge in the engine oil and enhance the durability of the bearing at the big end.
3. The crankcase reed valve has been made thinner for more efficient lubrication. The oil strainer has a stronger magnet to capture more sludge from the engine oil. Both contribute to better throttle response and smoother power delivery.
4. The cam specification was reviewed and the intake cam profile and the exhaust cam timing were changed to adjust the overall output characteristic. This establishes both high output and controllability.
11. The muffler body uses conventional bolts in end cap instead of rivets to simplify
the replacement of the glass wool packing in the muffler.
12. The Separate Function front Fork (SFF) from Showa, separates the spring and damping tasks. The right leg holds the spring, while the left leg incorporates the cartridge assembly to manage damping. This results in reduced friction, increased absorption performance, and weight saving.
13. The front fork inner tube diameter is 48 mm for optimized stability and absorption. The spring pre-load is now adjustable, which allows a wider setting range.
14. Dunlop MX51 series tires for the front and rear tires enhanced the traction performance.
1. The 249cm3, 4-stroke, fuel-injected, DOHC engine, with a compact and lightweight
design, powers the RM-Z250’s championship-winning performance.
2. The advanced battery-less fuel-injection (FI) system features a 44mm throttle body
with progressive throttle linkage and a 16-bit computer.
3. The fuel injection system uses a unique capacitor-assisted starting system and is
powered by a durable, lightweight magneto-generator after starting.
4. The aluminum cylinders with Suzuki Composite Electrochemical Material (SCEM)
coating are built for durability, light weight and efficient heat transfer.
5. The sturdy connecting rod and mirror finish permit a stunning 13,500 rpm maximum
6. Tuned to offer superb handling for a wide range of riders, the suspension delivers
excellent traction without sacrificing the capacity for quick turns.
7. Smart chassis design details include footrest brackets shaped to help prevent mud
8. Race-inspired disc rotors offer enhanced cooling performance and efficient mud
9. The high-quality Renthal handlebars feature a tapered design and are fixed to the triple
clamp on a rubber mount.
10. The gripper seat has projecting cross-shaped patterns on its red top surface to provide
11. Two couplers are included for quickly adjusting the fuel setting to suit the riding
conditions. One is for a richer fuel setting than the stock setting and the other is for a
leaner fuel setting. The customer can change the fuel setting to best suit the riding
conditions by just connecting either coupler.
12. 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.
