Ok....Cat had adjustable suspension before doo...so did yamaha....ill give you the accessories....
Doo is a copycat....they buy other peoples tech and call it their own....where do you think etec tech came from.....
Yamaha and cat had factory turbos way before doo...all doo has done is copied others tech and refined it...
Doos suspension front and back is cats design.
Only thing do can take credit for is rider forward....
