There are so many improvements to the 2008 250R it gets difficult to focus on what might be the one best change-up, but perhaps the most important upgrade is the move up to 17-inch wheels. I never had much trouble finding 16-inch rubber for the old bike because I knew where to look, but my test group seemed to agree that the new six-spoke wheels, wider rims and more accessible modern tire selection was at the top of the list, with an A+ for more neutral handling at low and high speeds. The new and larger 290mm front and 220mm rear petal-style rotors with dual-piston calipers give the ’08 250 much improved and noticeably more sportbike-like stopping power.
For me the most notable improvement is the suspension. I’ve put plenty of miles on the previous model and the ride always had an uncertain soft feeling. A 37mm Showa (36mm on previous model) front fork and a new Kayaba rear shock with five-way adjustable pre-load make for a stiffer and more precise, crisp ride. Surely adding to this stability is the improved chassis with diamond-type frame. The 26-degree rake angle is 1 degree steeper than the old 250, so the quarter-liter Ninja turns quickly and with seemingly little effort, making it loads of fun through tight twisty canyons.
Rounding out all of the improvements that make this little Ninja feel like a big bike is the newly engineered 249cc parallel-Twin motor. Although it’s based on the previous engine, Kawi says 70% of it has been re-designed, including new cams and a revised cylinder head, to result in a claimed 30% bump in mid-range power. Dual Keihin carburetors were fitted instead of a fuel-injection system. Fuel injection, although standard on the European models, would have pushed the sales price above the $4000 threshold where the American market allegedly draws the line. The Ninja’s powerplant engineer, Kozo Arai (no not the helmet guy!), was on hand to oversee our test rides, and although he spoke absolutely no English, he did show me his club-racing license from Japan where he competes on a ZX-10R, so you know the right guy was working on this project!
Weighing quite a bit less than the average test rider in our group, I had no problems with acceleration. Throttle response was even and predictable, another big plus for beginners. The bike seemed most happy at a steady 8-9 grand in every gear. I rode the little Ninja right up to redline in every gear and it pulled steadily all the way through. The best part was that I couldn’t even scare myself – I was laughing like a crazy maniac!
