a change requested by many owners of the previous model,.
Model Evaluation The camshafts are also new, with different timing on both intake and exhaust, and reduced exhaust duration to improve lowand mid-range power. Interestingly, the older model makes one more horsepower than the new one, although this may be due to the more restrictive 2-into-1 exhaust system on the ’08 vs. the older model’s 2-into2 setup. The Ninja now has an automatic screw-type cam chain tensioner (vs. the old model’s ball lock type) with an automatic adjuster that helps maintain better control of the valve timing. The greater amount of low-end torque is the new engine’s first noticeable performance difference. The ’08 Ninja can get going at about 3000 rpm, while the old one needs to be revved all the way to 4000 rpm before it would get off the line.

quate. Under heavy braking, the old Ninja would dive and rebound strongly, while the new one gave much better control.
Brakes, Wheels & Tires Perhaps the biggest change to the ’08 Ninja is the use of 17" wheels, which opens up a whole plethora of tire choices for those who like to change their bike’s shoes. The previous model had 16" rims, allowing for few fitments. Stock tires on the new Ninja are Bridgestone Battlax BT45s, in 110/70-17 and 130/70-17 sizes, front and rear. The bias-ply tires seemed well suited to the job. The front tire, which is 10mm wider than the previous model’s, is a lot less likely to chase pavement seams. The front brake has been increased 30mm in diameter to 290mm. Both the front disc and the rear 220mm disc are now petal-style to match the rest of the Kawasaki sport family. On the street, we found the brakes to be quite strong and responsive. In testing, we found that the bike was capable of a best 60 mph to zero stop in 121.5'. Like other twin engines, the Ninja provides a measure of engine braking, though it’s not as strong as it is on bigger motors.
Styling The Ninja’s styling has been updated to match its bigger siblings in the supersport class, making it look like it’s a fast bike. (During one test ride, a driver in a Porsche Cayenne asked “Zero to 60 in under four seconds?” Ha! The little Ninja takes almost eight seconds to get there.) The boxy fairings of yesteryear have been replaced with much more up-to-date flowing lines. It has a new upswept muffler to replace the dull black dual pipes on the older model. And there’s no engine size label on the bike to reveal its displacement. In fact, it closely resembles a Ninja 650R without the distinctive color-matched rear spring. An optional seat cowling to cover the rear seat is also available for $99.95. One tester disliked the smaller rear profile and taillight, which may make the Ninja less conspicuous than its predecessor, especially at night. Buyers may feel the need to add an LED taillight to make themselves more visible in traffic.
Attention To Detail
The Ninja now has two helmet locks located under the rear seat, rather than the previous model’s single pin-slide helmet lock that could only accommodate one lid. However, we found Handling the new helmet locks a little more fiddly to use, because the Dring had to be positioned in just the right spot to allow the rear seat The Ninja is one of the few (perhaps the only) sportbike one can to lock.

Model Evaluation Left: Even before its redesign, the the littlest Ninja was Kawasaki’s best-selling bike. Most are purchased by new riders and one-third of buyers are women. Given much more contemporary lines, the engine is 70% new, the chassis is revised, suspension improved, but the essential easy-to-handle character and low seat height remain. For all this, the price has increased only $500, to $3499. Above: The instrumentation gets a face lift for 2008. Analog gauges include a tach on the left (to keep tabs of its high 13,000 rpm redline), with the speedo, odo and tripmeters in the center and a brand-new fuel gauge on the right. Finally.
Above: The rider’s seat is well-shaped and measures just 31" off the ground, a real boon for shorter riders. The passenger accommodations are cramped but good for the occasional lift, and an attractive optional seat cowl adds a racey look for $99.95. Right: The machine’s sleek profile is obvious from behind. The exhaust system is changed from a 2into-2 to a single silencer for improved low- and mid-range torque. Dual catalysts scrub emissions. Left: Lightweight 17" wheels replace 16-inchers to provide a choice of tires. The front brake rotor is enlarged to 290mm from 260mm for more power. The fork itself is bigger, a 37mm Showa, and uses new steering geometry for improved handling.
TESTERS’ LOG I must admit that initially I thought there would be no serious saving grace with the smallest Ninja, as almost everything we ride these days produces at least twice as much power. In reality, very few of our current motorcycles are twice the motorcycle this one is, at least in stature. For me, the 250 has a dual personality: most anywhere below 7000 rpm, much time is spent waiting for something to happen, while above, if you don’t mind the howl of a high rpm engine, this motorcycle can hold its own. The narrow width of the clean bodywork makes the machine a natural lane splitter and offers decent protection; when commuting at speeds above 55 where the engine starts using its cams, the Ninja is willing to scream all day without complaint. In the canyons it was fun ride, especially downhill where gravity noticeably helped. This motorcycle is a smart choice for the entry-level rider, especially the more compact of us. —Danny Coe The first things that struck me about the new Ninja were the

much better suspension, the better braking and of course the better low-end torque. Riders can now get off the line without screaming the engine to higher rpm. Putting it through its paces in gentle curves and through the twisties proved pleasurable, and the new Ninja has lost none of the flickability of the previous model. It still has drawbacks due to displacement: as a 250, it still doesn’t have the torque to put more distance between me and erratic 18-wheelers on the freeway, and it’s probably not going to win any 1/4-mile contests. Still, there’s a lot to like about the Ninja: It’s quite comfortable, even over longer distances. Though it’s heavy for its displacement, it’s still much lighter than other bikes, making it easy to handle. Its updated styling gives the illusion of speed. The low seat height makes it easy for shorter riders to reach the ground. And the excellent gas mileage makes it an ideal commuter. All these attributes add up to make the Ninja ideal for introducing wide-eyed beginners to motorcycling. —Franke Santos
