2010 Kawasaki Ninja 250R
Rolling Proof That Less Really Can Be More
The Ninja® 250R has always been a great place for beginning riders to
get started, but modern sportbike technology means the littlest Ninja is a
great choice for more experienced riders as well especially ones experienced
at getting the most for their motorcycle dollar. While its twin-cylinder engine
might be small, light and compact, its 8-valve head packs maximum power into
every rpm. The 250R screams Ninja performance, from its sleek full fairing
and 17-inch wheels, to its UNI-TRAK® rear suspension and triple petal-disc
The lightweight Ninja 250Rs secret of success is its winning formula: A rider-friendly engine, real world performance and an amiable chassis topped off with Ninja supersport styling. The icing on this small Kawasaki cake is the motorcycles ability to transcend skill levels and appeal to all riders from novice to seasoned veteran.
At the core of the Ninja 250R is an engine that thrives on high-rpm excitement. The gutsy 249cc parallel twin is tuned for a peppy, yet smooth and predictable power delivery. The beginner friendly low- and mid-range torque comes courtesy of its dual overhead camshafts and 2-into-1 exhaust system. A silky smooth six-speed transmission lets riders to exploit the 250Rs powerband without fanfare from that low-end grunt to the crowd pleasing and lively top-end rush. Last, but not least is the little Ninjas silver lining its excellent fuel economy.
Wrapping the 250R are the fairing and windscreen that not only look great, but deliver wind protection for a wide range of riding situations. Tucked in behind the windscreen are more rider-friendly features such as the easy-to-read instrument panel and neutral indicator.
A natural riding position and comfortable ergonomics combine with lightweight handling, easy controllability and great throttle response for pure pleasure on city streets. Part of this great handling and stability comes from the 17-inch wheels. Bringing the show to a stop are the large petal shaped 290mm front and 220mm rear rotors gripped by powerful two-piston hydraulic calipers. Like Kawasakis other Ninja models, the 250R is equipped with quality components and tuned for class-leading performance.
Lightweight and agile, the Ninja 250R boasts low ownership costs and is a dominating force in the entry-level sportbike category.
Authentic Kawasaki Accessories are available through Kawasaki dealers.

2010 Kawasaki Ninja 250R Technology
The 249 cc liquid-cooled, DOHC parallel-twin engine was designed for rider-friendly response, the Ninja 250R's engine was tuned to deliver smooth, step-free power. Riders who use the full range of the engine will be pleasantly surprised by the ample high-rpm performance. To enable riders to enjoy this model for a number of years, many of the engine features contribute to durability and reliability.
Settings for the twin Keihin CVK30 carburettors were idealised for good power feel with low fuel consumption
Idealised intake and exhaust ports contribute to good off-idle response and smooth power delivery.
Direct valve actuation ensures reliable high-rpm operability. Valves with thin heads and stems reduce reciprocating weight. Valve timing and lift weredesigned for low- and mid-range torque.
Piston / Cylinder
Pistons feature reinforced heads and strengthening in the pin boss areafor increased durability. (Longitudinally) thick piston rings helpminimize oil consumption. Combustion chamber design optimizes thesquish area, maximizing combustion efficiency and thereby reducingemissions.
The 2-into-1 exhaust system contributes to low- and mid-range torqueand helps achieve the Ninja 250R's smooth, step-free power curve.
Slightly upswept silencer underwent extensive testing to determine chambe rdivision ratios and connecting pipe length and diameter. The result is reduced noise with minimum power loss.
Dual catalyzers, one in the collector pipe, one in the silencer, ensure strict emissions are met. Locating the first catalyzer as close to the exhaust ports aspossible maximizes its efficiency. Using two catalyzers enables powerloss to be minimized. (Carburetted models features pipe catalyzers; fuel injected models use honeycomb catalyzers.)
Latest generation Denso radiator offers superior cooling performance while minimising space and weight.
Noise-reducing ring-fan is operated by quiet-running print motor that also contributes to space savings.
Fins on the lower side of the crankcase further contribute to engine cooling.
Mechanical Noise Reduction
Cam chain tensioner like that used on our KX450F motocrosser featuresan automatic adjuster with threads and springs. The systemautomatically eliminates mechanical noise caused by a loose cam chain,reducing power-robbing friction loss.
The air cleaner features acomplex construction with reinforcing ribs that help eliminatereverberation, for reduced intake noise. Extensive testing to determinethe diameter, length and thickness of the intake ducting ensuresefficient filling.
The Ninja 250R features styling that would not be out of place on our larger-displacement Ninja supersport models. The striking full-fairing bodywork has a superb fit and finish that looks as good up close as it does from a distance.
All-new bodywork with new front cowl with a shorter top and a flatter mounted windscreen increases aerodynamic efficiency.
With its slightly forward-slanting seat and wide, raised handlebars, the Ninja 250R offers a natural riding position.
Full dash features easy to read analog dials for speedometer, tachometer and fuel. Also included are trip meters, odometer, and warning lights for neutral, turn signal, high beam, low oil pressure and overheat.
