I know I'm going to get flamed for saying this but sometimes the truth hurts. Whenever we take out a new "NEVER EVER" we always start them on the Yamaha 450FX with the Camso kit. The Camso weighs a ton and has no suspension but once you get to the goods it's by far the easiest setup to turn. Its low and turns on a dime because of the monorail. The track is flat out awesome from 2019 on, after they changed the durometer 2017 and 2018 had the floppy track. Kits are cheap as hell to buy, don't buy anything older than 2019. 2020s have all the bugs fixed (same brakes as Yeti, they put them on the DTS before the Yeti got them) and are super reliable. If Camoplast hadn't bought Yeti I'm sure they would still be making the DTS.
I still have a 2020 Camso kit on my backup ride and it goes everywhere my Yeti does. Full stop. My Camso bike has a full Yeti front end, spindle and ski which helps the Camso a lot, while the Camso ski is a little sketch on the trail it's really good in the spring on crust and it also works well in powder. The ski actually holds much better than it feels like it's doing but you really need to keep it on edge on the trail. The DTS spindle is absolutely bulletproof. I milled up a new deeper block for the spring preload adjuster which helps but the kit could benefit from a stiffer spring and more compression in the shock. If I didn't have the Yeti bike I would buy a new Ti spring from Renton with more rate and mod the shock. If you are over 200 lbs a spring change will probably be needed.
I've been preaching this since 2017 when I rode the first Camso, the monorail is the bomb. I always said narrow rails are the future and look around now. The Camso kit is the only cheap way into a narrow rail setup, IMO don't waste your time with an old wide rail TS, once you go narrow there's no going back so just start there.
We rate setups from easy ride to hard ride. My old CR500 with a TS 137 was top of the chart in hard ride, all it wanted to do was go straight, fast as hell but straight. It just wore me out. The FX/Camso is the winner of easy ride. Personally, I hate the FX but it's the easiest beginner bike out there and has a tall 5th gear. Depending on where you live you should be able to get and FX/Camso for really cheap. Ride it for a season then upgrade or keep it around to hook other newbies like we do.
