It looks like the Ninja 400 has been confirmed for participation in this years CSBK Amateur Lightweight Sport Bike Series, albeit with some specific restrictions on modifications. The new Ninja 400 will be required to compete using the stock exhaust header pipe and catalytic converter, although an aftermarket slip on tail pipe/end can will be permitted. A full race exhaust, allowed for other machines in the class, will not be permitted. The Ninja will also be required to utilize a provided Dynojet Power Commander, which will limit the maximum allowable RPMs to 9,500. Minimum permitted post race weight, with fluid levels unaltered, will be 325 pounds for the impressive new Kawasaki, slightly higher than the 320 pounds required of most other machines in the class. Looks like its been a bit of a challenge to get the 400 on par with other bikes in this category.
