Honest opinions - 900T vs Thundercat

25272 Views 223 Replies 66 Participants Last post by  one ton fun
I currently have a 16 xrs 800. Been a great sled and I love it, but it's time to snow check a fresh one. Most in my group have 850s and love them, but I want the piece of kind of the 4 stroke longevity. One buddy is a Thundercat, rode it once and was very impressed with the light steering, shocks were great, and the motor was smooth and fast. I've always been a skidoo guy, but the reasonable snow check prices cat has currently are making it a tougher decision. Skidoo it better fit and finish wise, but the cat has better shocks imo, led headlights and the ability to get a 230 trail friendly tune for pretty cheap.

If skidoo added a slightly higher hp options, led headlights, and a better track option, my decision would be easy lol... oh and taller spindles would hurt either.

I would really like to hear opinions or guys that have ridden both, good and bad of both sleds.

So the 900t is better out of the box even though the true weights shows it weighs more than a srx and still can't keep up
Sorry maybe I missed it but where does it say the 900t weighs more than a srx?
Yes. One of our members has.
@stevewithocd
YES I DID
I'm the OCD Man here

Before I chime in here I must back up & state that I was a Yamaha guy since '06
My '07 has over 25,000 miles & will still hang
I owned 2 SideWinders with the last one at 275 HP
The motor was awesome & VERY EASY & CHEAP to get good RELIABLE Horsepower
The chassis was actually well engineered, but the "smalls" & assembly were & still are a HUGE issue
The belt issues are "mostly" resolved, but at 275 hp......................well let's just say that's A LOT of power!

Although I really like the 850's & firmly believe the 850 POO is the best handling sled "out of the box", I'm just a 4-Stroke guy thru & thru cuz I try to get over 5000 miles a year
My opinion, don't need an argument here


I paid $13,150 for my 2022 900R "out the door"
I now have over 8500 FLAWLESS miles
NOT ONE ISSUE
If you know me from TotallYamaha then you know what I've been through

Not sure how to re-post my post, but I weighed my 900R against my old 2017 Winder LTX

HERE ARE THE FACTS:
Both fully loaded with gas burped twice (Winder held extra gallon)
Both 96 studs up middle
Both empty of any extra bags or goodies except spare belt
Both had 137" Rip Saw II tracks
I had a digital scale under skis using 2 by 4 and another scale in middle of tracks

900R=622
Sidewinder=694
That's 72 pounds difference

The Winder had on some heavier Curve skis & the QSR shocks were a tad heavier
The 900 had added adjustable bars & extra lights so about a wash

Lets just say 70 popunds

I have LOTS more to say but will keep this about weight
I do NOT bash the Winder or ThunderCat cuz they carry their weight well & I NEVER thought they were hindered by weight even in tight twisty's

I also weighed my 600R, an APEX, an 850 Poo, my trailer, a boat, neighbors dog with a collar on, 3 friends each with 1 foot on scale, my canoe full of water just to name a few.

It was summer
I was bored

I must say I disagree with your fit and finish assessment.
Still, Ski Doo is a great sled. I’m a TCat fan. I’m not going to suggest that AC is the way to go. I’ll stick to facts. If you’re into racing and you want the fastest and most powerful snowmobile engine ever created, then the TCat/Sidewinder is your deal. That’s not everything.
Ski Doo makes damn fine sleds and I have nothing bad to say about them. Don’t close yourself off due to brand loyalty alone. Every sled manufacturer has had issues. Wether it be engineering mistakes or part failures. That’s fact!
Don’t let anyone tell you differently.
I think this is an HONEST statement.
The 998 is INSANE!
I think my 900 is snappier since the Turbo is mounted on engine, but for $500 the 998 can get over 250hp with a STOCK muffler.
Add $500 in clutching & you're ready to run just 'bout anyone.
The Mach & 900R take A LOT more Ching to do that.

Now the Turbo Two Smokes may have sumptin'
They won't take a good running Winder or T-Cat, but it should be fun

I think they’d take a stock 998 Steve….at 100 lbs lighter and within 8-10horsepower, I’ll put my money on the Turbo Doo or Poo in a drag. Before I tuned my Winder, it was very close between a normally aspirated 850 and my Winder. I could get them but not by much. Now add in another 20 HP at least with the Turbo 2 strokes, and I think the stock 998 will lose that race. Mind you I’m saying “Stock” 998 here. Once the 998 is tuned then it’s not a match.

I have a 2022 900R renegade X model. It is completely stock. I did put a 1" track on it because a stick pushed a hole through my track right on a stud and stud hit my exchanger. I put the 1"track on it when I replaced it. I would like to try a stock sidewinder or Tcat. I have run many 850 and they don't have anything for me. I would like to try a stock sidewinder or Tcat but very hard to find one. I got 117 gps this spring on a hard packed railbed.

First of all, it's hard to find a Stock Winder or T-Cat
It's sooo easy to add STUPID power & ALL of us have OCD with snowmobiles, add in some Testosterone and BAAMMM!!! 250 Horse Power
With a 22 top tooth they run in the 130's

SOOO pick your fight carefully

A GOOD running 998 will take you on top, but not ALL are "good running''
I say this cuz the average 998 will run 115ish.
A few fixes & adjustments then 119ish
My old ECOTRAIL would run 121

Second of all, you must realize that these 900's DON't always run top end.
BRP pulls timing & fuel VERY quickly to be safe if any of multiple criteria is not perfect.
Sometimes 105 -110 is all ya get

That said, NOTHING last year when stock could take my 900R to 100 including every 998 I ran against.
I put a CUDNEY clutch kit on this year & only 1 of the 4 I ran could reel me in.
It took 2 miles for him to pass me including the BOOST that never caught me. HE WAS PISSED

Of course I weigh 100 lbs less than those guys
I have vids to prove it

You & I have 2 of the "good ones"
Some just topped out at 105ish
The MACH was definitely NOT the "King of the Lake" like DOO claimed

Although my clutch kit helped with consistency, I may try an aftermarket intercooler just to keep my top end more consistent

P.S: My POO bud bought a lower windshield & is NOW on a diet, but he doesn't realize that I'll be at my fighting weight of 165 next year with an intercooler...........I LUV this game

Clutch kit? Or pb80?
Cat’s still run same piss poor chaincase from a 2012 turbo. If you want to go fast cheap and change parts every year because of low quality get a cat. Parts on the cat cheaper then a Doo. If the cats were 40% cheaper then a doo I’d be riding one but at same price the doo is miles ahead if your goal is not lake racing

Yup, that chaincase left me stranded on my Winder in the woods…that was one of the nails in the coffin that pushed me away from the Yammicat. Sadly, Quality currently is not even close to Doo. And that’s a fact.

exactly. just need to be realistic what the person needs are. I owned 2 cats modded that I rebuild from ground up so i would make it home after my rides. Also there are brp dealers everywhere. Good luck finding parts for your cat on a sled trip.(not many dealers and Yamaha even worse)

It takes about $100 and an hour of your time to fix the chaincase problem.

Then u have the driveshaft issue, and the uppEr cross shaft issue, and the clutch issue, the heat shield issues, Coolant hose issue etc etc.

Yup…it’s the whole chassis…it’s not built well period.

And when my chain-case went, I had been alone, and you need to walk out of the woods(good thing I ran into a few guys on my walk that gave me a ride to town on a day that didn’t reach zero degrees F). Then go back and tow the sled to the nearest street, and drag it on the trailer(that’s when you see just what an ark it really is, holy smokes what a heavy machine).

Then try and find the parts needed, and drive about 80 miles total to get them. And then have another dealer who was nice enough to fix it for us. A total nightmare to day the least, and a trip killer that’s for sure. I salvaged a day and a half to ride, but it was tons of hassle and aggravation.

I get it, **** happens to all of us at times when sledding, but those chassis are junk unfortunately. As I said, that and a few other snafus pushed me to Doo, and it’s been great the last 3 years.

Opening the chaincase and checking drive line every fall would prevent this.
A procross chaincase will last a full season no problem.
If you want to run it a few seasons without doing any maintenance, well, then you walk.

In some cases perhaps. But That’s definitely not the case in my situation. It was checked by me, and my dealer in late November as part of preseason inspection and service. The top gear just stripped out and that was the end. Sure could have replaced the top gear every season…but that’s just lunacy when everything looked good at the start of season in late November when it was checked. And then goes to crap less than a few hundred miles after inspection. Definitely No neglect on my part in this case. It’s just poorly designed and Junk period.

BTW, my equipment is impeccably maintained…I try to ward off these exact situations, so your post is so off the mark in this case. And That’s what infuriated me about this. I keep my stuff beautifully. That’s how I knew it was time to jump ship.

It’s easy to hate. But they aren’t a junk chassis. There are plenty of them out there with 20, 30, or more thousand km’s.

Lots here. My bud has one with over 20000kms. All at 275.

Not hating, and Not saying you can’t get plenty of miles…but the stuff is poorly engineered. And if you want to rebuild everything on a yearly, or every two year basis..then ya, you can get mileage out of them. I don’t want to do that nonsense, not for the price you pay for them now.

With Doo, I don’t need to do that, and that’s the difference here. Routine Maintenance is one thing…reengineering the whole dam thing(or many things at the least) is quite another.

The point is, the quality is substantially less than BRP at this point. I hope they up their game going forward…I have nothing against any manufacturer. It helps us all if the competition is stiff.

Quite a few around here with high mileage as well but constantly repairing them and they really show the mileage. If your mechanically inclined and can do your own work that’s one thing but if your not their very expensive to keep them reliable
