Championship winning performance…..ready for you now.
Suzuki races to win, period. And, thanks to the hard work of Ryan Dungey in the U.S., the RM-Z250 is the AMA Supercross Lites West Coast Champion for 2009. But winning goes beyond the champagne. For the 2010 RM-Z250, Suzuki applied lessons learned on the track to turn up the speed, handling and confidence you’ll get racing every day, anywhere in the world.
Suzuki racing technology is everywhere you look: advanced Suzuki fuel injection is fitted for the first time on a four-stroke 250 cm3 Suzuki motocross machine. Further engine modifications boost peak power without giving up any of the low-end or midrange that has made the RM-Z250 the choice of top riders everywhere. Chassis updates improve handling with key suspension upgrades making the new RM-Z250 the perfect weapon for motocross racers worldwide. And there’s the eye-catching slim, aggressive styling that causes the RM-Z250 stand out at any track.
Think of the 2010 RM-Z250 as the perfect racing package.
Rider Safety
The RM-Z250 features a compact, lightweight and powerful 250cc 4-stroke engine design, a strong and lightweight aluminum chassis, Showa suspension components and many high-performance features for the ultimate 250cc 4-stroke racing machine.
The RM-Z250 engine is based around an over-square bore x stroke design, with liquid-cooling, titanium valves and double overhead billet cams. The engine is housed by a lightweight, twin-spar aluminum-alloy frame combining aluminum forgings, extrusions and stampings welded into a single unit. The whole package is supported by a Showa inverted, twin-chamber, cartridge fork and Showa remote reservoir rear shock.
The RM-Z250 features a unique aluminum rear swingarm built using hydro-formed, thick-wall tapered arms welded to a cast linkage bracket and forged axle holders. Other features include Dunlop tires mounted on lightweight aluminum rims with a special spoke/nipple design, plus Renthal aluminum handlebars as standard equipment. Included with this year's new model are all the benefits of Suzuki's race contingency, trackside support and Tony D School . All these added benefits are exclusive to Suzuki riders.
The RM-Z250 for 2008: it's taking the four-stroke world by storm!
Revised spring and damping rates inside the inverted Showa 47mm fork and piggyback single shock result in improved handling.
Modifications to the rear suspension linkage that reduce thrust backlash also improve traction and make for more consistent performance.
Suzuki fuel injection is fitted for the first time on a four-stroke 250cm3 Suzuki motocross machine. Derived from the pacesetting RM-Z450’s superlative system, the RM-Z250’s battery-less injection features a 43mm throttle body with progressive throttle linkage, a 16-bit computer and unique capacitor-assisted starting system. A durable, lightweight magneto-generator powers the fuel injection after starting.
Improved radiator louvers direct more cooling air to the twin side-mounted aluminum alloy radiators for lower engine temperatures. They are joined to the outer bodywork for
increased
strength without adding weight.
A new, stronger connecting rod and mirror finishing permits maximum engine output to a stunning 13,500 rpm.
A new muffler is fitted to optimize the benefits of the all new fuel injection system.
For 2010, the RM-Z250’s number plates have a black background.
Connecting the 19-inch rear wheel and the lightweight chassis is a new swingarm with an improved center brace for increased rigidity that also

concentrates its mass for enhanced suspension action and greater traction.
The RM-Z250’s twin-spar aluminum alloy frame has been redesigned with several key components to optimize rigidity balance and improve traction at high speed. The lower frame tube has thicker walls, 3.0mm versus 2.5mm, while the side rails are slightly shallower.
Revised cam timing works in conjunction with updated intake ports to boost power and torque at the top of the power band.
Advanced 4-valve cylinder head design with narrow included valve angle and titanium valves, plus a pent roof combustion chamber design for improved combustion efficiency
Automatic decompression system for easy kick starting
Compact 249cc, 4-stroke, liquid-cooled, DOHC, 4-valve engine - designed for maximum performance and light weight
Convenient hot starter on the right hand side of the handlebar.
Lightweight aluminum cylinder with Suzuki Composite Electrochemical Material (SCEM) plating for increased durability, efficient heat transfer and weight reduction
Strong, reinforced airbox designed for durability and secure intake seal
The Suzuki Advanced Sump System (SASS) features separate oil chambers for the transmission and crankshaft using the transmission as the oil sump, allowing low crankshaft placement, reduced engine height and a low center of gravity
Showa piggyback-reservoir rear shock absorber for excellent controlled feel and increased bottoming resistance
Foot pegs include optimized clearance between the mounting bracket and footrest to prevent mud from caking up
Gripper seat with projected cross-shaped patterns on top surface provides additional grip
On-the-fly clutch lever adjuster mounted to the clutch lever perch for rider convenience
Race inspired disc rotors provide better cooling performance and increased mud deflection in muddy conditions.
Renthal tapered aluminum handlebars with Renthal-labeled handlebar pad for reduced vibration and improved rider feel
Showa cartridge-style front fork with 47mm inner tube, plus 22 -way compression damping and 12.2 inches of wheel travel
Swingarm with lightweight construction for efficient traction, especially over the whoops
