I like how the sidewinder has progressed well passed the Apex, Nitro and viper. I was never a fan of yamaha merging with Arctic Cat. Takes away the purity and uniqueness of each brand in my opinion. (wonder who called who first on that deal). Yamaha had to do something drastic in order to stay relevant in overall marketshare. It worked out well for them in this case without the millions invested in R & D to develope a new chassis especially in the mountain segment. They did what they had to do sticking with their 4 cycle mantra. I still have a personnal fantasy of Yamaha releasing a 165" 850 DI injected 2 cycle twin in a ALL Yamaha chassis under 450 lbs. I know I would be dreaming in technicolor for that to happen. Just redesign that seat on the sidewider already! It's the size of a sofa! In the meantime I'll be sipping my DOOO-Laid.
