This is coming from a diehard Cat guy. Our club President has a 900 Ace and it has been flawless. He has over 15000 Kim's on it and never an issue. It's really stingy on gas and he drives it very hard. He has a hitch and is hauling a sliegh full of pickets , signs, etc all the time. It is a very impressive Snowmobile in every way.

Go with the 4 stroke - engine wise bulletproof. My dad has a yahama and it never has problems Unless he’s trying to be Superman and breaks a few idler wheels . Something to consider too is 4-strokes are a lot more predictable with regards to throttle control/response which for an average or below average rider will help them build confidence, will have more fun and doesn’t scare the shit out of them when you hit that wonderful powerband. I love but wifey not so much

I have owned a 600 ETEC (at 8,000 trouble free miles now) and ridden a TNT 900 ACE back to back with my old 600 ETEC.

The 900 ACE feels like 600 2-stroke weight-wise and accelerates like a 600 2-stroke (not a 600R) up to about 55-60 MPH, and then runs out of steam after that but will eventually work it's way up to 80-85 MPH if you have enough room. I imagine with some clutch work and mild mods that you can squeeze another reliable 10 to 20 HP out of a 900 ACE. But it will never achieve 600 ETEC performance levels.

But a 600 ETEC will be on it's 2nd or 3rd rebuild before the 900 ACE even needs its valve checked.

I have found that fuel economy on both sleds is real close with the 900 ACE doing slightly better.

If performance is your priority and you don't keep a sled beyond 10,000 miles, I would go with the 600 ETEC.

My wife wend from a 2010 f5 cat that she loved to a 16' ace 900 and she hated it it because it was just to slow and heavy but liked the 4 stroke because of how quite it was. So i bought her a new 17' yamaha viper RTX. We all hated it compared to the ride and handling of a skidoo. He now has the new 600r gen 4 and absolutely loves it. A lot more fun than the 900. I will say that if your just going to cruise around then the ace 900 will run forever i think. Amazingly quite but hate that electronic throttle. you have no feel for the motor and you find it is always wide open. JMO get the new etech!

Damn. Good info here. My wife currently rides an RS Viper (2016) and is pushing 5000 miles (usually the point at which I buy new). I want to get her on a Doo, but I'm wondering if the n/a 900 will feel slow to her...

There is a "sport" mode on the 900 (eco, standard and sport with just a flick of a button, and a light throttle pull), and frankly unless she is a speed demon the sport mode gives it a quick, hard pull up to about 70, then the 900 will top out at 80-90 (Im 270 and my 136 enduro will hit about 83-87 in the right conditions. I am extremely happy with the 900, good on gas, quiet and no blue smoke.

If you are worried about top end, get the 900 turbo. Believe me, it doesn't disappoint. I love it but yes, the ITC throttle takes some getting used to.
