Just a few questions myself , these machines would be a joint venture between Kawasaki and Suzuki to build the 450 dirtbike and ATV so It would not be likely they are just canned , but there has not been any proof of these machines anyway just rumors , Kawasaki has proven that they keep machines secret till they are ready to hit the show room, there has been rumors of different machines for years in the forums that have never came true , I would be that kawie and Suzuki and testing a 450 machine and will be getting one out soon be that is just logical thinking , not even a single magazine has a shot of the 450 and they have spys watching all the companies. Why leads you to believe there will be no 450 dirt bike or atv ? I have worked for one the top kawie dealers in the country in sales I can tell you that dealers and dealer rep do not know about new atvs till kawie is ready to release info to the public , some dealer make info just trying to keep people from going to other brands in hopes of a machine coming out in certain size or type.
