I test drove a 2015 gsx le ace 900 at the end of last season.. 4"-6" fresh snow, sled had under 300 miles on it. I'm 6'4", 240 lbs with gear on. Speedometer indicated just over 70 mph. Now, do the ski doo 4 strokes have the same computer break in limiter as the e-tecs?? Itc was on sport mode. Engine is very smooth and quiet, but I thought they went up to mid 80's or 90.. what are you getting for top speed???

I think about 80-85 bone stock from factory is all you get..... stock clutching and rpms I think are around 7200, what was it pulling with you on it for rpm, probably less. which could be a reason why it would only go 70. If you wanted more performance from this engine..reflash the ecu to raise the rev limiter and install a cudney clutch is a proven big gain in performance. lot of people do into the 90's. this sled has the horsepower of a 500cc level sled stock, but riding it doesn't feel like that in the trails as it has 600 class torque. it was never designed to be a top ender. I think clutched for your weight you should get 80 tho.

If you even more performance from 4 stroke doo try the 1200. This year they come with a higher rev limit 8800 rpms, with a clutch and header these give 800's fits. stock it will do around 100-105

We rented one in the UP last season pretty sure it got up around 85-90 or so.... maybe a little more , can't say for sure since it was a guest whom was the main rider.

My good friend has a 900 ACE and his top speed is 85mph. The sled drives like its electric powered, but slow on the top end. His wifes etec 600 is way faster on top end at 105mph.

Wrong sled for top end ACE not marketed for high speed cruising. If that is what you want from a 4s look at 1200 doo or Yamaha Vector or Apex.

if speedometer says your going 105, its more like 95-98 on GPS. that's why its called the dreamometer

Let me rephrase that and say the 600 etec is alot faster then the 900 ace on top end. You are right abought the dream meters but they are better now then they were 10 years ago. ( MPH was for refrerance)

I agree. The 900 ace with mods still cant run with 600 on top end.

Last year my speedometer and gps were 9mph different when you got in the 120mph area. 2015 800etec

Thanks guys. I'm looking to someday replace my Cat F 5 LXR. I like the ACE 900, smooth, quiet and efficient but I do want a tic more speed than 70 mph. Main snowmobile is a 2014 P O S ski doo gsx se 1200 I spring ordered.
With our bad snow year I may be able to get a deal on something the end of Feb or march. So far it looks like I can get the yamacat with yamaha engine, 40 more hp for about the same price as the ski doo ace 900. OR I can sell these dam things and ride my moterbyke all winter in Florida!!!

Why is doo 2014 gsx 1200 a POS? I thought gsx was a pretty good 4s sled.

Bought a 2013 gsx se 1200 new, wouldn't start 2nd trip, elec truoble, killed stranded, of course started at dealer, no computer code so I was charged for warranty work on a 2 week old sled. Never reliable, 4 dealers couldn't fix. Traded 2013 in on 2014 with best ever r-motion suspension, 2013 had a better ride than "best ever" r-motion. I posted a few threads on jdee site trying to get info on how to set up susp as no dealers or Val court helped. Diff springs on back, all combinations of air susp torsion and center shock settings.. my brother has a 2013 that runs and when we switch sleds there's a big difference. His rides way better. At least the 2014 runs... 7500 miles on it. A couple side notes : experts at Valcourt customer service recommendation was to replace shocks with renegade xrs shocks. They didn't even know the gsx se has an air ride suspension... I called every dealer in msp and some in wi and no one has any experience on this sled. Very dissapointing and frustrating. The folks that own these usually lIke them. Most guys on the r-motion anything are comparing them to an old school pre rider forward sled and I'm comparing mine to the same sled with the sc-5. I could go on and on even more than I have. I'll spare you all and stop lol!!
In a nutshell, I'm pist I got a new unreliable lemon that left me standed and "expert" brp dealers couldn't fix.. then I "traded up" and got a worse ride...
But for now lets worry about getting some snow for God's sakes!!
Merry Christmas everyone!!

Agree you don't buy a new sled to have problems like that. Yamaha suppose to have new platforms for 2017 probably want to take a look if waiting til Spring for a new ride.

Oh no!! Bummer!! I guess my expectations are too high. New anything should be perfect. I'm starting to realize no sled is perfect. After all they aren't heart-lung machines!!
