Sure they can make a triple, Doo already makes a lot of triples.  And they even turbocharge them.  Did someone really ask what's the point?  Triples sound great and they are smooth, and they have way more torque than a big twin.  Great trail engines.  At least in my experience.

I believe the manufactures went too twins for the trail manners and much better low end torque!

A 900 triple is going to have more than 50% more torque than a 600 twin.

I'd take that long lasting, dependable, smooth, easy on belts, etc.. triple vs an 850 for any usage case.

They went to twins to reduce cost and weight. No other reason.

Not "any usage"... you'd hate it vs. a current two stroke mountain sled.

 

Especially in bottomless powder. Way too heavy.

Manufacturer's could charge a premium for a triple so cost is no issue.  I think a triple is in Arctic Cat's wheelhouse.  They just released the new blast engine so their engine people should have plenty of time on their hands (if they didn't get fired).

I had a 1997 Mach 1 and two Mach Z 800 triples. Love the sound of the engine and exhaust on the 800's.  Couple of pics of my 2003 that I used in my for sale advertisement in 2011. Had 16000 kms on the 2003.  Never had it apart, original track

I was thinking the same thing. Maybe they could make up a new chassis for it while they’re at it lol

If the hp wars started up again. I think Polaris would be the first one with a big triple.
Being an all 2 stroke sled builder and their history of triple's.

IDK? I think triples look a bit awkward.

Do not want to argue with you, but triple sales where shrinking because of the new twins (lighter, better handling and low end torque). Go back and read some of the articles and you will see why triples went away.

I'm a big guy. The added weight wouldn't mean much to me compared to the added power, smoother engagement, less likely to pop a piston 20 miles from a road, etc.
My current ride is a 1200 Expedition. I think I could handle a 900etec just fine.

They got replaced by 4 strokes.
Still plenty of people that would love a triple 2 stroke. They were great engines. Everyone suddenly started screaming for light weight. That is what killed the 3x3s. That cry has gone silent. Longevity would be quite a bit better on the triples. That is starting to matter more and more as well.

^^^Yes. A triple has better volumetric efficiency, lighter moving parts and a shorter distance for flame propagation, less chance of detonation. The longer crank can be a problem, but a design like the 850 etec could make that much less of a deal. I still have and ride a zrt600. Almost 18k miles, original crank and crank bearings, still at .0015”” runout, makes about 125 ish on 87e. I still enjoy it, and the sound is pretty cool. Corners very hard with a few cheap mods.A modern one would be cool!

IMO snowcross killed the triples. Seemingly overnight the industry changed to lightweight twins because snowcross gained so much popularity. A 900 two stroke triple using current technology in a low chassis would be awesome. Don’t need big suspension to rail smooth trails and fly down lakes at warp speed. I think there’s enough old guys like myself who would have to have one for nostalgia, so they would sell decent for a couple years anyways. Doubt we’ll ever see it but it costs nothing to dream. Maybe this is what Cat needs to pull themselves out of the hole they’re in.
