Yamaha 2017: Everything You Need to Know About the Sidewinder M-TX SE Turbo

All you turbo-loving chute climbers can rejoice. Yamaha has a cool new Sidewinder Turbo M-TX LE complete with a new 998 Genesis triple 4-stroke and factory turbo system. The sled is rated at 180 horsepower and comes with new body work and a new steering system.

Yamaha has drastically increased the performance level for 2017 with the introduction of the all-new Sidewinder series of snowmobiles, featuring the Genesis 998 Turbo, along with the return of the completely overhauled VK540.

The Sidewinder takes the lead as Yamaha’s new flagship snowmobile, and will be available in different variations for R-TX, L-TX, S-TX, X-TX, M-TX and an all-new sub category, the B-TX series. The B-TX series is for low elevation boondockers who want a 153” track length and a narrower ski-stance than traditional deep snow models, but with the sea-level clutching and moderate lug height to tackle the trails when required.

At the heart of the Sidewinder is the diabolical all new Genesis 998T which has made the Sidewinder the new production snowmobile HP king. The turbo comes factory-installed from Yamaha’s facilities in Japan and delivers top of the class performance with the reliability customers have come to expect from Yamaha.

The 2017 Yamaha Sidewinder M-TX has a new, fresh look thanks to revised body panels.

The same front and rear suspension, track and tunnel as the 2016 SR Viper M-TX returns for 2017.

We had a chance to ride the new Sidewinder M-TX Turbo. It has the power and traction to get you anywhere on the mountain. Boost is ready at the flip of the throttle, and the sled rockets forward like a galactic spaceship. Yamaha athlete Jason Soucie pictured.

Here it is, the all-new 998 Genesis Turbo... the Sidewinder.

Wow, lots of little improvements all through there.

 

[zenk]

The post says everything you need to know.... But I see nothing about weight? What does this thing weigh?

 

[Norway]

Extensive! Who will be the first to put a programmer/tune on this and go 200+ Hp??

Very informative write up. I'm impressed with the technology and hope this engine is well received as it should be. As a former yamaha faithful, this sled comes a little late for me as I bought a new Doo this winter that so far has impressed. I'd like to see this motor/chassis stick around so I can get the opportunity to own one in the future.

 

[cacsrx1]

I would imagine it still pukes oil when its upside down?......or does it say somewhere that that problem was addressed.

 

[Topogigo]

New motor weight

I am surprised that the team that developed the engine turbo package did not talk about weight reduction. This looks like the kind of engine Yamaha should be proud of. I am just surprised given a clean sheet that they did not use light weight materials and make it a part of the launch hype.
If they didn't make it lighter we already have a 180 hp turbo in the 9000 cat??? This looks like an incredible machine.

 

[cacsrx1]

Not sure how it could weigh less than the current viper.

I agree, I wish they would have given some weight figures.

I did see that cat is saying that the new 998t engine alone is 10 lbs lighter than the 1100t engine.

.....or the loss of oil pressure at sustained high angles of attack. Still the Proclimb chassis with different skin?

Both issues addressed by engineers. Its all good.

When is everyone going to finally figure it out

ITS NOT ABOUT THE WEIGHT!
Yamaha is not on a weight loss diet!

That is CLEARLY not their goal with their sled line. They appear to be FAR more interested in

Yamaha has let all of us know they will let the 2 Smokers chase after weight and sacrifice EVERYTHING else on that alter in pursuit of it.

Hey Randy, any chance there's some videos out with the sidewinder MT-X in it? I'm dying to hear this new motor and see it perform in the mountain version!

But they can do both,that's the issue most people have,they can make this sled allot lighter with some simple things.
Smaller lighter seat,that 30lbs chaincase,the hood & panels look way better not sure if lighter.
I can keep going but you get what Iam talking about,at this point I won't buy another yammi till they address some of the weight.

I agree! I think my next sled will be an AXYS. I was a die hard 4-S fan and love my APEX MTX for the durability, fit and finish, but I am getting old enough its kicking my *** at the end of a hard day of riding. I have ridden the AC 1100T and the M8000 and absolutely do not like that chassis. I think Yamaha could do a lot better with the weight reduction through the current material and engineering that is out there. I definitely applaud the factory turbo and hope I could throw a leg over one for a spin, but after riding the RMK's from my wife's '07 to a buddies '15 I think that is the way I will be going for my next sled...

Curious what you didn't like about the pro climb chassis if you like the pro. Rider position steering and other things are similar between the two. I've ridden both and find them similar. Being a bigger person I just like the stronger chassis. Thirty pound weight penalty is worth it. And my biggest pet peeve with my current sled is the snow and ice buildup and the Polaris is bad also with that. Pro climb is a very clean chassis

The biggest issue with the Proclimb chassis is the outward slope on the panels covering the fuel tank. The Pro, AXYS, and XM have flat panels and for technical downhill riding when you want to dig in a knee it's almost impossible on the PC chassis.
The weight is whatever...people know what they weigh when they buy it so they shouldn't complain. The fact that the chassis has room for improvement could have been dealt with. It's obvious that Cat engineers don't ride tight steep trees.

likely the sled gained weight with the turbo and associated components. but, one has to consider power to weight ratio. assuming its easy to crank up the boost beyond 180

the new 850 by doo changes these rules. it was made to handle boost and be reliable, imo it has more technology than the 998 by yammie. yamaha is lost when it comes to a mountain sled and what the masses want

 

[Calvin42]

I think it's a great product. And you are correct, it's not about the weight "for a trail rider". For mountain riders (for the exception of a very small group) it is all about the weight. Todays technical riders want something light and nimble. After owning a four stroke turbo, I understand both sides of the coin. However, with the majority of riders being in the older age group (me included), I don't want to wrestle with a heavier machine in the mountains. I think the four stroke is awesome and has it's place in the snowmobile industry, but for "most" it's not in the mountains. If it were, all four manufacturers would all have four stroke mountain sleds. The fact is they don't. Yamaha continues to develop the four stroke for the lake racers of the Midwest and Northeast. Those are the areas that provide them with the profit margin they are looking for. Someone mentioned in another thread, the style of riding sleds in the mountains have evolved over the last ten years. For some, slaying chutes is still something that gets their blood pumping, for others, it's where can I find the best snow by taking my light weight sled through some tight technical terrain. The four stroke has the ability to get there, but at what cost. It's us old guys with money that can afford todays new sleds. It's the young guys that aren't quite so sore at the end of the day that don't mind the added weight. Great job Yamaha, I think you developed a great sled for a small percentage of mountain riders and a HUGE percentage of trail riders.
