3. Introduction
After years of unchallenged domination, the best-selling
Ninja® 250R sportbike had finally begun to see
competition from other manufacturers. Make no mistake,
it still outperformed the challengers by a significant
margin on the open road, but why simply outperform
them, when you can totally dominate? The new 2013
Ninja 300 thoroughly dominates its lightweight sportbike
competition on the performance front, and it also
significantly ups the ante for refinement, ease of use and
overall practicality. Thanks to a new digital fuel injection
system, and a new F.C.C. clutch with assist and slipper
functions, this new 300 is the best lightweight sportbike,
by far, when it comes to overall performance and sporting
capability.
5. What’s New
• 296cc liquid-cooled, parallel-twin design offers far superior highway passing power and clearly
dominant acceleration compared to other lightweight sportbikes
• New Digital Fuel Injection (DFI®) system uses dual 32mm throttle bodies and provides both
improved fuel economy and cleaner emissions compared to last year’s 250
• New F.C.C. clutch with assist and slipper functions provides more power handling capability
with significantly less effort. Design also makes clutch easier to modulate and helps reduce the
effect of back-torque to reduce wheel hop when downshifting
• All-new bodywork features an aggressive and edgy design with strong Ninja family DNA that
sets the Ninja 300 apart from its lightweight sportbike competitors
• New frame uses high-tensile steel main tubes that are 150% more rigid and provide superior
feel and agility compared to last year’s 250
• New 10-spoke 17-inch wheels look great and the rear rim has grown ½” wider, allowing the use
of a larger 140-section rear tire for 2013
• Revised six-speed transmission features a new roller-type shift drum for smoother actuation
and stronger gears for maximum durability. It also offers wide selection of ratios to match varied
riding conditions and its positive neutral finder makes it much easier to find neutral when
stopped
• Kawasaki Air Management System (KAMS) uses a special deflector to channel hot air from the
back of the radiator, so that it exits the bottom of the motorcycle, instead of being blown onto the
rider
• Low 30.9-inch seat height and tapered seat boosts confidence for smaller riders
7. New 296CC Engine
• Compact parallel-twin design offers good mass centralization for nimble handling
• Tuned to deliver smooth, step-free power with excellent mid-range and high-rpm power for
effective highway performance
• New intake ports taper from 1mm wider at the throttle body to .5mm wider at the valve seats
• New 23.6mm intake valves are 1mm larger than last year
• New cam chain design reduces friction for increased power and efficiency
• Revised 10.6:1 compression ratio allows the use of regular 87-octane unleaded gasoline and
helps reduce operating temperatures
• New lighter pistons reduce reciprocating weight and feature a hard anodized coating for
reduced friction and increased performance at every rpm
• Revised piston bottoms efficiently route cooling oil across underside of piston
• New lighter piston pins reduce reciprocating weight and help preserve a high redline
• New shorter connecting rods offset new longer crank throws
• New sleeveless “open-deck” die-cast aluminum cylinders are 800 grams lighter and feature a
friction-reducing “T-treatment” plating
• New thicker crankshaft balancer webs help offset the new longer crank throws
• New crank journal bearings are made from a stronger alloy for increased durability
• New crank cases feature improved oil passages
• New large-volume 2.4 liter oil pan features cooling fins and better ground clearance
• New easy-to-access cartridge type spin-on oil filter helps simplify maintenance
9. New Aerodynamic Body Work
• All-new bodywork features an aggressive and edgy design with
strong Ninja family DNA that sets the Ninja 300 apart from its
lightweight sportbike competitors
• New floating windscreen design helps reduce turbulence and
rider fatigue
• Aggressive dual-lamp headlight design, minimalist tail section
and separate seats further enhance the aggressive visual impact
• Two helmet holders conveniently located under the rear seat
• New two-stage under-seat storage compartment can hold a U-
lock or similar device and is hinged for easy access to the tool kit
located beneath the storage tray
• Two hooks under the tail, plus two behind the rear passenger
pegs provide anchor points for securing items to the rear of the
bike
