It has been this way for a few years, preorder only......It will be really sad if there are no Sidewinders available in-season. I suspect that most potential buyers were not willing to commit to a spring order, and Yamaha will lose customers as a result. I wonder if it is a situation where Yamaha didn't have the ability to produce the engines in sufficient quantity, or whether it was AC being unwilling to allocate more time on the assembly line to the 4-stroke sleds? Maybe a little of both?
