The first round of the 2008 Willow Springs Motorcycle Club Advanced Kawasaki Ninja Cup has been postponed due to a late arrival of equipment. The 10-round series, which will feature Ninja 250s with minimal modifications, is now scheduled to start as part of the WSMC Classic Series race weekend March 14-16. The new 2008 Kawasaki Ninja 250s have not arrived in the dealerships in sufficient quantities in time for riders to prep them for the track, Advanced Kawasaki’s Kevin Jump says. That could mean that those who got their bikes early would get an unfair advantage over their competitors in the season’s points battle. While all versions of the Ninja 250, Kawasaki’s venerable entry-level sportbike, will be legal for the class, only the 2008 bikes will qualify for Kawasaki contingency money. In addition, Advanced Kawasaki, a Buena Park, California dealership, will support the class with cash payouts every month and a KLX110 motorcycle to be given away to a competitor at the end of the season, Jump says. The motorcycles must conform to the WSMC general motorcycle requirements, with limits on additional restrictions in an effort to keep costs low.
