Great question and I have spent a lot of time on the expert, freeride and edge in the Gen 5. Comparing it to my 2022 Summit Expert set at 34 with t-motion 175 and a summit freeride set at 36 with t-motion 165. I felt the expert was 20-25% harder to ride for me, I ride steep stuff but not where if I make a mistake my sled will roll into a tree and break, that is 38-40 degrees and steeper. I know everyone says they ride that but sorry not everyone does, there like the polaris the expert is a weapon it hold an edge better. However like a polaris being so planted loses fun in carving etc. The team has spent tons of time on t-motion, with flex edge track with out it and also locked out in every configuration. In deep snow it is really splitting hairs. but I found when the snow was hard with then a bit of fresh the sled was harder to initiate especially for my 5'6 145 pound body, I picked the freeride every time which had 36 front end and felt more nimble than my 2022, it was my favortie, I know my real fav will be the summit x with 34 front end and t-motion and flex edge. The flex edge and tmotion work, they side hill extremely well, one thing you have to remember is it will wash out if you spin, but if you know traction, like riding a trials bike vrs dirt bike then that is the difference. One thing to note is chris B is constantly saying the ski doo wonkey skid is dumb, however he rides a carbon rear skid for weight. Next time you have one of those grab the rear wheels and flex it, the carbon skid flexes similar to t-motion since if it was super rigid it would crack. The problem this year I see is every year ski doos top sled is the easiest to ride, the 2022 expert is the best and easiest sled ski doo has ever made, but for 2023 they make not a better sled but a different sled for different riders. So choose carefully what you do and dont do, for the guy or girl who is sidehilling in steep steep trees all day, yest expert will be a knife, but for guys who ride trees, not extreme steep, under 38 degrees and deep pow and everything in between you might like the summit x or freeride better. What ever you choose you will get use to. It is why I changed my order from 2 experts in 175 and 165 to a 165 turbo summit x and a 165 summit turbo freeride. Can't wait. Aslo Jason and Denis who are guides ate ckmp and put 10-15 thousand km on sleds each year and absolutely rip, say they have never found that t-motion stopped them from anything, jason only deleted it for hill climb racing and denis who has spent the most time on the expert said he preferred the freeride to the expert cause he was less tired at the end of the day, the less tired means better you ride. These are all just thoughts to give you an idea of what to choose. There is no worng or right since only you can know what you do most. Also a bigger guy will find the expert easier to tip over than me because of strength and height. cheers dave
