Hi, I am kind of a rookie to the dirt bike world, however I am loyal to yamaha. I have noticed that some of the major manufactures are making there 450's efi. So i was wondering if you all knew when yamaha is going to jump on the band wagon? My 05' wr450 is getting tired and is need of replacement, I would think a new yamaha efi would be right up my ally. Well thanks again guys.
