Every time I see one of these post from you I feel bad for you. You don't get out much do you? Have you checked the left over Doos? They are more plentiful that the Cat/Winders for certain. The left overs are always the in season models with cheap shocks on them no matter the brand.
The Cat chassis rides and handles awesome and requires nothing to get it to work like it should, yes its heavy, but still out handles and steers easier than the Doo, along with riding just as well on the rear suspension. Nope, the Cat is not built as well and needs some mods to the driveline that the consumer shouldn't have to do, but once done, its a reliable machine. Doo really does have better engineering, bearings and things like that, but still has a poor front end on it. They both have their flaws.
If there were really "lots" of guys dumping the Cats/Yamahas, I'd think I'd see them over here talking about it, but I really don't see many people at all bragging up the 900t on this forum. No where even close to the happy owners that were on the 1200 forum when the 1200 first came out. Everyone loved the 1200, not too many on this forum in comparison to that, I've seen a "few" and very few that have switched to the 900t from the Cat chassis, but only a couple fellows that brag up the 900t.
I have a buddy with a XRS 900t and been a Doo guy myself for years and LOVE the brand, but I'm certainly not impressed with the 900t from Doo. It rides rougher up front and the front is no where up to the level of the Cat, not even close! Its also one slow machine next to the Cat. Only one of my group of riders has a 900t and eight of us all ride Cat or SideWinder Yamaha turbos, its only myself that "maybe" would switch to a turbo Doo and only if they fix the flaws. Don't see where "lots are switching" myself.
That said, I want so badly to order a new sled for next season but the 900t is lacking in so many areas, power and speed being the biggest, throttle and the sub par front end need work. If they could fix these issues, I might order one. As of right now with what is out there, I think I may order up a new Thunder Cat. for 2021. Doo messed up bad not sticking with the 1200 engine for turbo and fixing their lousy front end. There is no machine out there right now I really want bad to be honest. I like my Winder but it's getting long in the tooth, I'd like to try something different, but Doo is making it hard not stepping up their game on their poor front end and that wimpy 900t engine.
I've never been left stranded on of the 1200's or the Winder. Except the one time I had a PB80 cup break on my 1200 Doo, but I can't blame Doo for that.
