Can't speak for the bikes but I won't install an untrimmed track . In certain conditions it probably isn't noticeable but there is no way your going to convince me an untrimmed track is more nimble unless it flexes one way or another . Road a few untrimmed like mine and they just take a little bit more pressure on the pegs to respond and they are squirrelly , washes out easier .

The only thing a straighter lug track has is more bite in deep snow but there are manufactures that are figuring out other ways .

The shorter track sleds have had the lugs curved for years , subtle but they have been doing it for a reason , more is not always better but the R&D gets stopped when the majority rule .

Guys I think you need to step back and think about it. The only thing good about a 3 inch track is the size of the paddle for soft snow. cutting it in any way will reduce its intended purpose. If you are concerned at all about hard snow don't even consider a 3". The 3" should only be for people who convert their bikes back to tires mid February.

Personaly i would never trim the edges of a track. Every powder track is desiged to move snow inwards and provide float and lift. Concure is one of the newest designs and ot even has a spot in the middle whit no lugs for that purpose. Triming edges does the opposite. A tall lug in the middle puch snow out and away from the center of the track.

If you are concerned about trail performance fine. Trim your edges.
Powder big no no!

All valid reason , what works for one doesn't for another .
This does both for me , the center lugs shovel the snow in and the cut edges give me the traction I need .
It's more universal , not specific .

All interesting points forsure. That's why I asked the question. I'm always looking for extra handling or performance advice. The track really is amazing goes anywhere you want to go. I've put over 60 hrs on it and I m still not done yet.

Do you have a before / after pic ? The trim job is so clean it's kinda hard to figure exactly what you did. Props for that.

The pictures are lost in the cloud , it's a peak 2.5 154 x 16 multi durometer cut to a width of 12 3/4 . The easy part was cutting the width , clamp threw the windows a long board on the inside of the track so it's sitting on top of the drive lugs . It has to be thicker than the board that will be clamped on the outside .
Measurement is important to the out side because that dictates your width and the skill saw will be guided by it . Clamp like a 1x on the outside of the track for the skill saw to run on and the skill saw will sit high enough not to hit the outside drive lugs , the inside board is the backer for the skill saw to ride along .
It takes longer double checking measurements than it does to cut . Loosen the clamps roll the track measure , clamp , cut . I just propped a piece of plywood in the track to keep it open .
The hard part was doing the curved lugs , the only curved tracks I've seen are the OEM Hawk camoplast/camso tracks the custom and kits just straight edge it , made a template to guide a sawzall and put an edge on the reverse side of the blade . Cuts like butter once you get use to it , forcing it won't . The cuts are far from perfect so leave the cuts a little long . The finishing is done with a bench grinder , with the template . The end lugs are actually curved , the pictures are deceiving .
I gauged the curved lugs meaning I spent some time with the bench grinder .
you'll want to do this in a well ventilated area or outside , garage even with a fan gets a little cloudy , dust mask highly advised .
Probably have a good six hours into it with basic tools , I'm picky when it comes to detail at times .

Stumbled across these , the pic with the two , before and after . The cut one I blew , hit a hidden stump weakened it and later when I was getting hard on the throttle things gotta fuzzy . The last pic still wasn't completely finished .
You ripped a track in half?? Impressive. Rail damage?

After figuring out what happened I was just a little hot under the collar , walked , crawled and cussed back to the cabin about a mile grabbed the freight sled and retrieved it , think it tries to hurt me at times . I was heading to the parking area to pick up some people that showed up , some of the best riding is solo , no heads to count . Of course they found me strapping the Hawk down . When it blew it went just like blowing a belt wide open . All I really remember hearing is A belt go , engine going ballistic for a millisecond grabbing a hand full of brake and a face full of snow . I pulled the track out of the snow it was kind of buried , the drivers held on to it so I actually torpedoed and when I got up and looked behind me with the helmet light I didn't quite comprehend it till I looked at the skid . Like where the H _ _ _ is my track . No damage to the rails they are 3/8 , 9.47mm built to abuse and the weight to prove it . I think some guys ride with me just for the laughs :)

After riding side by side with a A3 compared to my A137 with a tapered track in every kind of snow condition I want a 3” track uncut. It does seam to float up on the snow as someone had comment on. We have the exact same bike.
Makes me wonder does anyone make a 137” track that is not tapered just like 2 1/2” straight across?

I Know C3 Powersports offers 120, 129 and 137 track options in their Camso/Yeti 2.5” track, the 137 is 12” wide and it’s not tapered. Goes for around $1100 or $800ish USD. Not too sure how that would work on the 11.5” Aro though, never tried it.


Was the Aro3 still decent on set up snow? I’m on the fence between snowchecking the Aro3 Velocity or the Aro129le. I ride southern BC steep terrain and deep snow Nov-April; then hard snow May-June and can only have 1 setup.

The CMX non-tapered 2 1/2 inch works awesome on set up snow. For 900 bucks you could just swap the track in mid April?

From what I am seeing on my buddy aro3 though, it does pretty well In setup snow also.

aro3 all the way! U wont regret it. Best decision i made!! I ride eastern Wa/ oregon with all types of varying snow Conditions. And dont let people tell u a stock 450 or 500 doesnt hav enough power to turn the 3.. just doo it!!
