2 Stroke or not to 2 Stroke

I need some help from riders with experience on both the 4 strokes and 2 strokes.
Here's the situation :
- I have only owned 4 stroke sleds in the last 10 years. I currently have a 2014 Viper that is due to be changed out.
- AC has stopped the 7000 line for next year and Yamaha has limited the Viper to only a couple options.
- I see no other '600 class' 4-stroke sleds out there for 2020. I can either do a 900 ACE (scared of not having enough power) 900 Ace Turbo (Do I want to spend a premium and get more power than I want) or do a Sidewinder/Thundercat (and have way more power and spend than I need)
- After todays Arctic Cat spring sale with significant discounts, I cant help but consider a 6000 or 8000 series AC, more specifically a Riot 6000 or 8000 with the 1.3" lug.
- I generally do trail riding (90%) but love the other 10% of off trail riding.

Now come the questions. I love the throttle response and torque on my Viper and of course the reliability. Will I get that out of the 6000 ?
What is longevity like on a 600 and 800 2 strokes these days? I recall the days of 10,000km's/6,000miles and you are in a for a rebuild. Rarely do you hear of a blown 4-stroke, but I'm assuming 2 strokes must be better now.
What is belt life like on both the 600 and 800 ? (i'm assuming the response will be different for each)
I can get 220km's on a 39L tank of gas on my Viper. I know this is not great, but it is good. How does this compare to both the 600 and 800's ?

Thanks in advance for your response. I'm really struggling this round with what to buy. Nothing other than the Riot stands out and says 'Buy Me'.

Well, I have always had 2 strokes until recently switched to a 4 stroke to gain the reliability. I did not like the 10,000 mile rebuilds either. I am hearing the new 2 strokes are now more reliable maybe just like a 4 stroke but only time will prove that. You will probably miss the running quality of the Viper for sure if you go 2 stroke. If I had to go away from my 4 stroke, I think I would get used to it pretty quick and enjoy it just as much as long as it didn't have engine troubles.

My dad is on his second 7000. He really wanted to ride my new 800 this year. After he road it he wants to go back to a 2 stroke.

I've had both this year, 18' 800 and 19' T-cat and they both have their strong points for sure. The 1" lugs (it is studded) on the T-Cat pretty much relegate it to being happiest on groomed trails. It is fast and a ton of fun and I have it handling amazing on the trails. It is not so happy in fresh powder or off trail stuff and also not a "ton" of fun when/if you get her stuck!
The 800, on the other hand is an awesome mix of power, trail speed and could still handle some casual off trail excursions pretty well without burying the nose. Don't get me wrong, the 1.25" track is not ideal for boondocking, but definitely better off trail than the heavier front end of the 4 stroke, coupled with a bit more lug height out back.

I love both sleds, and now the wife says she wants to ride on mine, not her own, so the T-Cat may double as the family truckster, ughh. We've had such an amazing month of February, snow wise, here in Central MN, I can honestly say every time I've gone out riding lately has been absolute blast. Even launching that Thundercat has been fun and interesting, as it wasn't something I pictured doing with that sled. The I-act is also pretty amazing!

If you are riding the 7000 now you will find the 6000 lighter with plenty of power, same hp I believe. It just seems like more. Belt life is very good. I get about the same kms on a tank of fuel. Best advice is try them. I have about 8000kms on my 14 600 and itís still running strong. I will not buy another 4 stroke sled. The two strokes sleds just keep getting better. (Jury is still out on the 800 ctec imho)

I like the "no smell" and quiet 4-strokes more and more. On trail I now ride an old Bearcat 660T because of that and fuelconsumption. I had an 1100T @230-240hp in -12, really loved it, switch to an M800 in -13 and I could really feel the -40kg in weight off trail but for trailriding I would go 4-stroke. Tried a Lynx Commander 800 (Ski-Doo Expedition?) and was suprised how much louder the track was compared to the old BC also heard that trottle by wire is not that plesant.

M800 -13, Speedwerx full exhaust, PCV. BC WT 660T -06

M800 153" -13, Speedwerx full exhaust, Power Commander V, Racewerx Mountain bumper, Arctic cat vented panels, USI X2 Triple Threat Stage 3 modified.

what is your dressed weight? If you are a bigger person, you may want the 800 for power over the 600. I am about 175 in gear, I ride f1100T and can ride my sons 6000 with no complaints. The 6000 has plenty of power for the trails. I would not take my turbo off trail, front too heavy. would wear a person out. I would take the 600 off trail and be able to have a blast. The newer two stokes just keep getting better and better. They will last, it boils down to how they are operated/maintained. Its no different than your truck, if your foot is to the floor day in and day out, its not going to run as long as if you drive it sensibly and take care of it.

The new 2 strokes are definitely better today. Even just a few years ago, most 2 strokes burned pistons etc even with a lot of care taken to deice fuel and make sure everything was perfect. I had plenty of those for years and maintained everything very carefully but I grew tired of the constant repairs after 40 years or so. When 4 strokes came on the market, it was the perfect time to sell many of them and I was sold. Mine runs like a car. Start it and go daily without repairing anything outside of routine checks now and then. Like I mentioned, I believe the 2 strokes are better now but why go back once you've experienced a quiet, clean and reliable engine.

FWIW, I'm 5'7" and probly 250-260 fully dressed (short, fat, mean, miserable,, ugly and balding....LOL) and I ride a '14 ET C-tec 2 600 129" w/ min studs. Sleds does absolutely fine w/ my LA on it and gets around 15-17 mpgs on most days. Sleds does smoke upon initial cold start up and once warm, no more smoke and suit does not smell of smoke either. She is great on trail and tho it has a 1.25, does ok in deep stuff. Also have a '07 Jag Z1 w/a 121" 1" track which is my go to back up sled and love how it rides. Also have a '08 F6 LXR LE, which was mine, but now the wife's which I don't ride and only she rides it (I will if I have to and ONLY 2 others will be allowed to ride it). Yes the Z1 is a tow truck needed if ya get her stuck, but the ride is incredible for a 121.

I'm sorta in same boat as OP for I'm toying w/ a '20 ZR8 LTD and unsure which sled to sell, '07 or '14. Both have been w/o major problems, just the occasional hic-cup but always great runners. OP, PM me if would be interested for more info on my '14.
