Right now, my single biggest concern about the Sidewinder is the ability of the chaincase to handle the power output of the engine. I wouldn't mod it to up the HP so that isn't an issue.

Did ACat update it...make it stronger? Maybe they don't need to make it stronger as it was on the 1100 turbo was it not? I'm not familiar with how the chaincases handled the power of the 1100 turbo. Maybe somebody with experience can chime in?

Yeah I'm interested in better handling not more engine 162 ponies plenty.
I do like Yamaha quailty & hope maybe this chassis is better than Viper fit & finish. 130hp Viper not enough for us and SW too much but much rather have too much than not enough. You buy new I buy used cherries from Kip so I'm thinking down the line a SW might be ok so will keep an open mind and run one see how I like it.

In the SW Kip thread, he stated that this is the same chassis as the Viper, basically the 2012 pro cross with new plastic and LED headlight.

This is just about snowmobiling and the UP, can't we all get along?

I think the new SW is pretty cool but can guarantee I won't be buying a new one. Kip teases me when I test ride one of his demo sleds......"he tells my buddies, he won't buy one, he buys once every 20 years"! He teased me forever about bringing my 2 stroke Viper up year in and year out. "Hey looks like he's here to ride the vintage ride again." "Do your friends make you ride in the back of the pack so they don't have to smell your 2 smoker?"

I finally bought a super clean used Attak from him a couple years ago. I used to buy new every year or two in my younger days. After I had kids that all ended. I am currently building a new house now so a new sled is way down on the list. But that is the beauty of these 4 strokes. 10,000 miles is nothing on the motor. Sure there is the rest of the sled when it comes to maintenance items but it sure isn't pistons,rings and cylinders.

The same but different if egos exactly the same like how I sit on it then no go for me. I'll know quickly when I plant my butt on a SW.

2017 Yamaha Sidewinder - First ride! Posted on March 2nd by Snowtechhttp://www.snowtechm...der-first-ride/




Every now and then a manufacturer brings out a new sled that exceeds expectations and just plain works, with a magical combination of a strong engine, compliant suspension, capable ride and sharp handling. The 2017 Yamaha Sidewinder will change your impression of what a 4-stroke snowmobile is capable of. Imagine having a snowmobile with nearly 200 horsepower , regardless of the temperature or elevation. Imagine having a turbo-charged three-cylinder one-liter engine that features an intake manifold pressure management system that all but eliminates any and all turbo lag. Imagine a sled that rockets to warp speed, at your beck and call. You whack the throttle and find out how long your arms are as they stretch trying like **** to hang on for dear life!

sidewinder1-1-300x200.jpg



For 2017 the Yamaha Sidewinder will be offered in TWELVE different models, ranging from a 129” R-TX SE all the way to a 162” M-TX SE, with a host 137”, 141” and 153” models in between, in all kinds of lug heights, colors and shock option packages. Each is powered by an all-new 998cc turbocharged in-line triple with 50% more torque and 40% more power than a stock SR Viper (FX Nytro) 1049 engine. This new 998 turbo is similar to Yamaha’s YXZ (side-by-side) 998 engine, but fitted with lower compression and (of course) a turbocharger featuring an air-to-air intercooler and a host of features designed to provide seamless power delivery of exceeding and copious amounts. This package delivers power of at least 180 HP (in conservative Yamaha dyno testing) that we expect will be more like 190 HP when tested by other dyno facilities. Yamaha boasts the Sidewinder will provide the best power to weight ratio in the industry with up to 30% more power to weight than the closest competitor (2016 models) – let’s just say it’s FAST!

Most of time when we hop on a sled with this kind of power it is all motor, lacking in the handling or suspension departments, or just plain one-dimensional (on-throttle only). They’re fun to go in a straight line, but suck in the bumps or through the corners. But when you hop on the Sidewinder you are not only BLOWN AWAY by the engine’s hard-pulling and long-lasting power explosion, but you also instantly notice how smooth it is, how quiet it is, how linear the power is on both acceleration and deceleration, how well balanced the entire machine is front to rear, never pitching or diving. You can’t believe a new sled could be so, well, refined, right out of the gate. Like, “WOW they did a great job with this one, it works so well!”

sidewinder2-300x224.jpg



You wonder how heavy it is, knowing there are three turbo-charged 4-stroke cylinders banging away in there, but the engine’s power masks the true weight with each burst of the throttle. Even when you chop the power and expect the weight to transfer abruptly to the skis, the sled remains planted and balanced with keen cornering prowess, which is a good thing when you are still carrying some good speed. With the engine’s power being so responsive and predictable it is incredibly easy to ride.


The cool part is that it always runs the same, regardless of temperature or elevation. It never needs to be recalibrated, no clutching or gearing changes, ever. Where an 800cc 2-stroke might be making down around 120 HP (or less) at higher elevations, you will be making 180-190 HP anywhere and everywhere. With NO turbo lag it responds to your commands (almost) instantly, lifting the front end to carry you over the bumps, or blasting out of corners with the utmost in authority. You will have mod sled performance with stock sled reliability, but it is so smooth, so linear, so refined.

You can’t help but be impressed and somewhat proud in realizing somebody at Yamaha finally took the snowmobile business seriously enough to allow the development of such an incredibly awesome snowmobile. Every power-junkie on the planet is going to want to ride one of these just because of what it can do and make you smile like **** every time you ride it. It’s darn intoxicating to have this kind of power delivery at your disposal. You will be saying things like “Oh my gaawd, I can’t freaking believe this thing!”

Given one word to describe this sled, it would be “intoxicating”. You become totally intoxicated by the torque and acceleration and how well-calibrated the entire machine is as a complete and total package. It not only goes fast, but works extremely well at everything else that is important to a high performance snowmobiler. This is going to be as close to the perfect 4-stroke snowmobile as you could possibly imagine. Not only is this a blow-your-mind engine package with power delivery that will make your arms hurt from trying to hang on, but with each model you will find the machine to be incredibly well calibrated. From ride quality to handling, from clutching and gearing to running quality and consistency. From the moment you turn the key and hear the Genesis Turbo to the moment you dare squeeze the throttle to the moment you see the landscape rush by you in a blur, you will not believe a 4-stroke snowmobile could possibly work this well.

The mag sounds like this SW is a very good, very high performance sled. That is good for Yamaha. I don't think anyone ever questioned their ability in that part. I don't know how much market there is for SW power, and cost wise? I was looking for a 110/120 hp class sled in different forms. I am very disappointed, and now I don't think we will ever see a "pure Yami" sled ever again. Yami will probably just become the 4 stroke power supplier for AC. AC will never become Yamaha. There is way, way, too much "Cats PRIDE" for that to ever happen. Just ask ezra!!!!

Kip; Maybe you can relate to my post above????? I am not intending to be "down" on Yamaha in any way. Just disappointed, and have ran out of "waiting".

I guess I don't understand why a Midwest trail rider would want a big bore two stroke, for marginally less than the turbo Yamaha/cat??(price wise)...especially with the Yamaha warranty.

As far as them making a 900....how have they sold (ski-doo's 900)...I would bet etec 600's out sell them 2 to 1.....Maybe I'm wrong but I just don't see that much of a market for them....I do think Yamaha should have taken an "updated" phazer motor, and put that in the cat chassis...give it anti engine breaking, and EPS....and maybe just a bit more HP...and you'd have a mileage champ with 500 liquid performance..just a nice trail sled....I still think the Yamaha story will unfold next year...all this speculation is just that...speculation....it's their 50 anniversary next year (2018)...if all they have are BNG yamacats...then you'll have your answer...but I have a feeling new 100 percent yami's are coming next season...I wouldn't give up on them yet.

Think you guys are dreaming if you think Yamaha is coming out with a all new lineup and should start preparing for disappointment now.
Why would they bring this engine out now .....plus share it with a competitor no less....if they had a chassis almost ready??
Not saying they won't bring one sled out but if they do it will heart of market 120/130 hp, maybe less.
Think the days of complete line up changes are over. Just too expensive not enough sales volume.
Had heard even BRP told dealers after this year not to expect anything new for a very long time.
Would love it if I'm wrong but that's how I see it.

Never seen doo stand pat ever always improving & refining chassis & engines. I'm sure doo will continue to refine everything & a lot more they can do with 600etec & 4s engines. Platforms run about 5 years prolly longer in this day & age to get bene of ROI for new tooling.

Agree 50 years is special!!! I am in hope you are right on with your thoughts. We do have a 900 renegade, and it is everything and more than what we expected. I have no idea how many Doo sells in comparison to 600 e-tecs. I do know the dealers I work with have never had a hold over 900. I Looked to find a "16" renegade when the no snows deals came out, and they went fast. I was not near quick enough. 900's hard to find used also. Doo really did a good job on the 900 as far as the balance, and handling goes. It is uncanny how good the 900 renegade will handle deep snow. That said, I don't want anything heavier in the front/nose of the sled. I absolutely feel the front end weight on the 900 Doo is the key to it's success. It was to be my wife's ride, how ever to my surprise, I use it a lot. Would I like a little more on the top end? I will say yes for me. How ever for no more times than I would use more top end, I would not give up any of the rest of what this sled does so very well. It just seems to me that if you have to put EPS on a snowmobile, it's too nose heavy up front for me. Just my thoughts, no rib intended.

It really is all about what you like to do. I am a midwest trail rider and still prefer the light weight 2 strokes over 4 stroke. our group owns them all, 800's 600's 900's 1200's. I still like the 800 class 2 stroke the best personally, but others like the 1200 or 900

I dont know the numbers but doo has SOLD a ton of 900 aces. I would bet they sell as many if not more than 600 etec in recent year. It really has become a popular choice

I paid 12,550 for a new 850 Gade X. Looking at the sidewinder model 137 with the good shocks it retails for 3-4000 more than the 850 X
