Tried a 900 ace (my impression)

My wife's next sled will be a 900 ACE Renegade. She has a 2014 Yamaha Viper XTX now and likes everything about it except for the throttle. She test drove the 900 ACE and fell in love. She said the throttle was so nice and easy and the sled was very comfortable. I was also impressed with the 0-70 grunt. On a winding trail this would be a fun sled to ride. I am torn between getting another Yamaha for myself or switch to a Doo 900 ACE Turbo Renegade or a 850 Back Country. I love the gas and go of my Yamaha's but like the fit and ride of the Doo's. It would be nice if Yamaha had a 150 hp sled with in the pro-cross chassis and easier throttle.

Most caveman haven't figured out how to operate a DBW sled and EPS is not needed unless your sled handles like a three legged Bison in the snow. Carburetors and Manual transmission and two stroke snowmachines will never be replaced by anything better...

Bingo! Perhaps this is why Doo sells so many of these 900 aces!

Just curious, what is the percentage of Doos Sleds does the Ace make up?
Had heard years ago that the only reason they were being built was to offset emissions percentage of there line.

A 500 2stroke would smoke it. It is right there with a 440 I bet though....fanner that is....That DBW is lousy on the ACE....even in sport mode.

I can't give you a answer, but just a guess. Doo offers the ace engines in many different sled models, and chassis. Utility, sport, 2ups, etc. This tells me they sell very well in the market. Left overs are by far fewer, and not near as friendly of "deals" on them. There are few to find in the used market, and they sell very quickly. I am sure the "ACE" engine line was developed, and bought about for not only emissions, but for versatility of different applications it would work in. Modular Design Manufacturing. Such as being modular, part of the final vehicle in design from the get go. Being designed in as fit, weight, balance, CG's, handling as to the final product what ever it is. BRP uses variants of this "ACE" engine in watercraft, sleds, UTV, and now on road Rykers. It was a absolute surprise to myself how this engine performs! It's just a convenience of fuel economy, and fuel type makes no difference in it's performance. I, and many others have put on many, many miles with E gas, no concerns. On our Canada trips, it's a relief knowing we have a very safe fuel range of 240+ miles, no matter riding conditions. Gets the same mpg however you ride it. Fueling places up there aren't on a regular basis where we like to go. Western Ontario is worse so yet! My sled has no lag, or soft spot in "sport" mode. Light weight, and handles like no other 4 stroke. Very good tight trail sled! Love it.

BTW, SkiDoo only recommends 87 octane in the ACE if it is ethanol free. Good luck finding that. Otherwise, 91 octane is recommended.
 
The throttle delay unfortunately isn't a programing change, its a airflow distance per what I read. I agree as a Yami rider, this 900 has a lot to offer once you get used to the delay. I haven't rode the turbo, anyone know how it compares to the Viper and Apex? Is there any shootout data around?

I have a good bud with a place near me who got the 900 Turbo and we've been wanting to line them up with my Sidewinder (just for grins , mind you...mine's a tad stronger than stock) but I've been sick and we haven't managed to make it happen as yet....he LOVES it, BTW

I have an 18. Zero throttle delay here.

Agree.... the Yamaha 973/1098 is the only High performance 4 stroke purpose built sled engine ever developed, let alone purchased to be used in another line of sleds.
Ski- Doo doesn't have their heart in the 4 stroke world. Only Yamaha did and they did it very well.
They answered the pathetic US government EPA bullspit call with what will forever be the one and only high performance NA and more recently 204 HP turbo enhanced 4 strokes.

And when we're done with that we can toast to the Yamaha 4 cyl. 1000cc R-1 motor on a rubber band transmission....another snowmobiling milestone that sadly will never be duplicated.

Dang....doo you share that s*** you been smokin' ?

Was there ever a time that the Doo 1200, from 2009-2018, wasn't consider better then it's Yam counterpart? I honestly thought that was pretty much common knowledge.

I just assumed it was the sled that drove Yam out of the sled building business, but maybe I'm wrong.

To each there own.... I saw DTD make his Ace 900 as fast a trail sled in the tight and open twisties I ever need to keep up with....Pretty sure he is a snowninja.

And gave us some inside knowledge so we can chuckle when guys say..."it will run with a 600 up to...." lol

I think skidoo was listening to riders who were asking for a "family sled" that didnt break the bank and offered years of low maintanence service (for some a lifetime). The oem`s had for years been in a race to build the badest, faster than the competitions sled and failed to pay attention to the entry level/family market so it is nice to now see their focas on that aspect of the sport. Sleds are just getting to expensive and this sled is a good fit.
