I wouldn't touch a FrozenMoto with a stick.
I'm sure most of you know I have been riding Snowtech since almost the beginning. Five of my friends in WA ride Snowtech as well. After three years the kits have more than proven themselves to be quality built units that were very well engineered.
I have put a few rides with the new Yeti SS kit on a KTM 450SXF or FE501, and have rode the regular Yeti kits, briefly rode the new ARO kit on a 450SXF as well. I had a few friends with MotoHax kits but they couldn't keep the tracks on them long enough for me to take one for a spin (no joke). Had a 14 TS before Snowtech, and a 2Moto before that. I haven't tried a CMX so I cannot give any input there.
The Snowtech is totally bomb-proof and reliable as you can get. I haven't had a to touch my 17.5 120 kit since I mounted it. I got it last spring mid-season. Haven't touched the belt, chain, track, nada. I play with the suspension every now and then to dial it in and that is it. I don't have anything come loose on the kit... I just ride it. I have not heard of a single person tweaking/breaking their forks or spindle at all. I have never blown a belt, or a single part at all on my 17.5 kit.. and I have crashed into a lot of stuff. I've dragged the belt cover across big rocks during early season riding without issue, I wore through a ski rock riding until I could see rocks through it without bending the spindle or my forks, not to mention all the times I have scorpioned over the bars from hitting stuff under the snow. It has grease zercs everywhere, UHMW track and chain sliders/guards everywhere they should be, and all kinds of neat adjustments like an adaptable rake spindle via eccentric bushings. It rides awesome with the huge amount of suspension travel in the skid and adjustable air shock. You can get the new CMX track on it (I hope to get one soon) which looks really good. It comes standard with a coilover 3rd shock (one that doesn't blow apart) that has two different mount holes for leverage rates. I weighed the 2017.5 Snowtech 120 and the skid weighs 118lbs. Complete with spindle and ski 137lbs. Rolling resistance is almost non-existent. I can push my bike across the shop floor with two fingers. It is noticeably less than even the new Yeti SS kits that are also belt drive.
The new Yeti SS kit. It is light, and feels very nimble while riding. The SS track is really good, it hooks up and the skinny feels like a dirt bike tire. The parts look nice, everything looks quality. I can noticeably feel the suspension in the skid bottom out compared to the Snowtech. Strength and QC are the main problems. I could give a laundry list of little things that break on these kits, not to mention some of the pulleys that have come on new kits that are out of alignment causing belts to break. The belt covers crack if you hit anything, and the black plastic around the covers crack. The titanium linkage arms on the rails break at the welds. The cross members in between the rails have bolts that come loose, causing the cross members to disappear in the snow. Random Ti bolts come loose in the kit, then they shear off. The spindle center blade cracks/breaks if you hit things, causing the forks tubes to crease. The skid shock cross members break. The new 18 skis break due to lack of support from the short center skag. We have broken 3 skis so far, using 17 skags now. The RRS third shock mounts break. Have had none of those issues on the Snowtech., The Yeti rides nice when you aren't constantly fiddling with it. I'd just rather deal with the extra 20lbs of always working snowbike, and not worry about 300lbs of broken down snowbike when I am up in the mountains.
I briefly rode the ARO kit. Track felt good, shocks are real nice. Kit looks like a pop can in comparison to Snowtech and Yeti. Lots of people are folding up spindles like wet noodles. It has been outsourced to overseas for mass production and it shows, sadly. I loved my 14 TS... "made in USA".
