(KMC), recently announced a three year extension to their long-standing partnership with Infineon Raceway. Kawasaki and the raceway have maintained a relationship since 2001, and as a result of this extension, Kawasaki will continue as the “Official Motorcycle, ATV and Personal Watercraft” sponsor of Infineon through 2010. KMC will also retain title sponsorship of the facility’s AMA Superbike event each Spring. “Kawasaki has been one of the raceway’s strongest partners over the years,” said Steve Page, president and general manager of Infineon Raceway. “We appreciate the outstanding support they have provided for motorcycle racing at this facility and look forward to our continued association with the Kawasaki brand.” Infineon’s annual AMA Superbike Championship event, which is titled: “The Kawasaki AMA Superbike Showdown” is held in May. In addition to that title sponsorship, the partnership will also include: an annual large-scale Northern California-based retail promotion in advance of the Kawasaki AMA Superbike Showdown, year-long signage placement at Infineon Raceway, and Kawasaki corporate ticket packages and hospitality at all of the raceway’s major events each year. “Kawasaki and our Northern California dealers have benefited greatly from the relationship with Infineon over the past several years, as have the many racing fans who have taken advantage of the special ticket packages offered through our dealerships,” said Bruce Stjernstrom, Kawasaki Director of Marketing. Kawasaki fans will have something to look forward to during the upcoming AMA Superbike Showdown, as the Monster Energy Kawasaki factory roadrace team will enter a two-rider pairing for the 2007 AMA season.
