After years of great competition the best-selling Ninja 250R sportbike had finally begun to see challenges from other manufacturers. So they unveiled the new 2013 Ninja 300, which 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.
The new Ninja 300 sportbike is powered by a larger 296cc liquid-cooled, parallel twin that’s tuned to deliver smooth and predictable power around town, plus excellent high-rpm performance on the highway. This upgraded engine offers significantly more performance than the old 250, while its new digital fuel injection (DFI) system provides improved cold starting, crisp throttle response and better fuel economy than last year’s bike. This new engine has nearly 50% of its parts upgraded from the previous model. In addition to its new long-stroke 296cc displacement, other engine upgrades include: new intake ports that taper from 1mm wider at the throttle body to .5mm wider at the valve seat, new 23.6mm intake valves that are 1mm larger than last year, a new cam chain that offers reduced friction, a revised 10.6:1 compression ratio that allows the use of regular gasoline and lowers operating temperatures, and new lighter pistons that feature a hard anodized coating for reduced friction and increased performance at all rpms. The underside of the pistons was also revised to more efficiently route cooling oil across their surface. Further highlighting changes for this model, it features new, lighter piston pins to further reduce reciprocating weight and help preserve a high redline, new shorter connecting rods to offset new longer crank throws, new sleeveless “open-deck” die-cast aluminum cylinders that are 800 grams lighter and feature a friction-reducing “T-treatment” plating. It also has new thicker crankshaft balancer webs to offset the new longer crank throws, new crank journal bearings made from a stronger alloy for increased durability, new crank cases that feature improved oil passages, a new large-volume 2.4 liter oil pan with cooling fins and more ground clearance than the previous model. Topping-off the changes, a new easy-to-access cartridge type spin-on oil filter helps simplify maintenance.
A revised six-speed transmission features thicker gears to help cope with the extra torque from the 300’s new engine. The transmission also features Kawasaki’s positive neutral finder to make finding neutral a cinch when stopped. This efficient engine and transmission help the Ninja 300 provide plenty of enjoyment from the initial learning curve, all the way through advanced sport riding, track days, and club racing. Operating that transmission is now easier than ever, thanks to a new F.C.C. clutch with assist and slipper functions. This new clutch reduces lever effort by up to 25%, while increasing the clutch’s ability to handle the extra torque generated by the 300’s more powerful engine. The new clutch’s slipper design also helps reduce rear wheel-hop that can be caused by aggressive downshifting.
The Ninja 300’s extra “go” is complimented by the extra stopping power offered by its petal-type front and rear disc brakes which feature new longer-lasting brake pads offering a more progressive feel. Its 290mm front and 220mm rear brake rotors are gripped by powerful two-piston hydraulic calipers. Like all Kawasaki Ninjas, the new 300 is equipped with high-quality components and was tuned using feedback from professional riders at Atopolis raceway, to help ensure class-leading performance and an entertaining ride for even the most advanced riders.
The Ninja 250 was always known as one of the best handling sportbikes on the market. To uphold the family honor, the 2013 Ninja 300 features a new frame that uses new high-tensile steel main tubes that are 150% more rigid than the tubes in last year’s model. Revised tube shapes and additional gusseting also help provide better longitudinal stiffness for better feel during extreme sport riding. Though the main frame is more rigid for better handling, not all rigidity is positive; that’s why Kawasaki engineers designed new rubber front engine mounts that help make this model noticeably more smooth, despite the extra power produced by its new 296cc engine.
