Scorpion sidewinder

Snowtech November 2016, page 42. " as manufacturing transitioned to thief river falls, Arctic added only one new Scorpion model-the Sidewinder- for 1981, basically an Arctic Cat dressed in Scorpion clothing"

So, what other model names could yamaha get from Cat? Or, could this also mean the sidewinder is the end of the yamaha/arctic relationship just as the sidewinder was the end of the Scorpion/arctic relationship in 1981?
