Sudden over-application of the brakes, or braking on low-grip surfaces (surfaces with a low coefficient of friction) such as wet asphalt or manhole covers may cause a motorcycle’s wheel(s) to lock up and slip. ABS was developed to prevent such incidents. Kawasaki ABS systems are controlled by high precision and highly reliable programming formulated based on thorough testing of numerous riding situations. By ensuring stable braking performance, they offer rider reassurance that contributes to greater riding enjoyment. And to meet the special requirements of certain riders, specialised ABS systems are also available. For example, KIBS (Kawasaki Intelligent anti-lock Brake System) is a high-precision brake system designed specifically for supersport models, enabling sport riding to be enjoyed by a wider range of riders. And by linking the front and rear brakes, K-ACT (Kawasaki Advanced Coactive-braking Technology) ABS provides the confidence to enjoy touring on heavyweight models. Kawasaki is continually working on the development of other advanced ABS systems.

“The 250SL models are powered by the same liquid-cooled, fuel-injected 249cc engine. Kawasaki claims a peak output of 27.6 hp at 9700 rpm and 16.7 lb-ft. at 8200 rpm, both down from the 300 models’ parallel-Twin which claims 38.9 hp and 19.9 lb-ft. The single-cylinder models do reach their peak numbers at earlier rpms however and claim strong low- to mid-range torque. The 250SL models have their own styling to visually differentiate themselves from the 300s. The Ninja 250SL has a bit less bodywork than the Ninja 300, revealing part of the trellis frame while up front it sports a single headlamp.” -----

“KAWASAKI has just unveiled two surprise new 250cc single-cylinder models for 2015, the Ninja 250SL and Z250SL. Both the new 250 models were launched for Asian markets earlier this year - the Ninja 250SL in February and the Z250SL in May. At that time it was not known they were also headed for Europe.” ----- visordown
