Would you buy a new, 2-stroke Yamaha if they offered one?

[couch]

I'm kind of thinking a lay down, opposed 4-stroke might be the ticket? Kind of like a Subaru flat 4 but with 2 cylinders lopped off. Get that heavier engine way down low and back in the chassis and the weight won't be as noticeable.

I just got a new sled magazine and it said the wet weight of a '13 Indy 600 SP is 609lbs. It also has a 11.5 gallon tank. I forgot, what is a short track Nytro's wet weight? I know my RMK felt like a complete feather compared to my Nytro. The base RMK is just a long track Indy.

I think the 08 RTX was 520lbs dry....I'm guessing full of fuel it just over 600lbs.....so comparable to any 2 stroke....the issue is the heavy engine placement over the skis....but many people say that the Skinz front end makes a huge difference, also relocating the rear skid back 4" also makes a world of difference. The race sled they built the past 2 seasons is the way it should have been built from day one....I here they are leaps and bounds better than the stock Nytro.

Again the issue is chassis / engine placement / balance more so than 2 vs 4 stroke for off trail sleds. If Yamaha had addressed the issues head on, lots of brand loyal buyers would not be forced to jump ship! If I was a trail sled rider I would have bought a new Yamaha 4 stroke. All HO 2 stroke engines eventually go boom - even Yamaha (have a pair of 1200 cc triples in my jet boat and they have gone boom).

Shaddow,
The Nytros with the race kit worked pretty well at XC racing. Makes you wonder why Yamaha didn't upgrade the production Nytro with better parts? They lost a lot of customers (me included) because they wouldn't make upgrades and meaningful changes.


Back to the weight and balance thing:
I've been thinking about it and the AMsnow wet weight figure for the Indy is a mistake. They listed it at 609 lbs. That is 162 lbs heavier than the dry weight! WTF? I found the wet weight for an '08 Nytro RTX is 599.2 lbs. http://maxsled.com/snowmobile/max-sled- ... t-reprise/

I found the wet weight of a studded '11 Rush 600 and it was 564 lbs. Since there is 17 lb difference between the Rush and Indy that makes the Indy 547 lbs wet.

I also found the dry weight for a 137" '14 XF7000 and its 545 lbs.


Here are some more weights from some older sleds.

That says its an xf8000, which would be the 800 2 stroke right? xf7000 must be heavier.

Maybe im blind, but judging by the "engine power 113" I I think it's a 6000, the N/A twin 4stroke?

113 kilowatts.. and the 8000 is the 800 twin.

113 kilowatts =
151.535496 hp as per google.

Guess I'm the only one looking at other brands.

If I had the cash I think right now I'd spend it on a 2014 Renegade Adrenaline with a 900 ACE.

But I don't have the cash, so instead i'm putting a new track on the RX1 and plan on enjoying every minute on it anyway.

10-4 on that bud , in the same boat , can not justify spending 20k anymore.

Doh! The thread I found the Cat tag in was talking about the Viper. I didn't read the model that closely. The 8000 is an 800cc 2stroke. 545lbs can't be the dry weight. Maybe that's curb/wet weight? I'd believe that. Seems like its a tag of a European model?

Its a different kind of FUN that up to this point has not come close with a 4stroke at least in a sled. With the Dirtbikes it is more about high maintainence costs with a 4 st.

It is interesting how in the dirtbike world the roles are reversed. My 4s KTM 450 has been a complete nightmare maitinence wise and my last bike a KTM 300 2s was a mix gas and go special.
Latest rumor in the dirtbike world is that Yam and other Japanese manus. have been waiting for the E-tech patent to expire and have DI dirt bike protypes built and ready to go. If it's true who knows but there is for sure a planned DI or SDI smoker in the works from Spannish motorcycle company Ossa in the works.

Could mean something, who knows??

Interesting design with the cylinder leaned back and and the pipe exiting the rear unlike most 2 stroke bikes. Rear shock off set to the right side as well, cool looking to say the least. Awesome to see Ohlins still doing stuff, too bad not for the North American market. They had some awesome shock tech.

There is still a place for 2 strokes along side 4 strokes in the power sports market and Bombardier has shown that. I think Yamaha dropped the ball going totally 4 stroke with their sleds and missed out on a huge chunk of market that I think they could still be a big contender in. Who knows, maybe it will come back to sleds.

Yamaha was the one company that could have made a 2stroke motor, or 4stroke that would have changed the game...... the problem is they don't have the faintest idea how to design a sled around it.

Agreed and unfortunately that has been the case with all six Yamaha sleds I have owned. Solution= Cat/Viper chassis with 800cc Yamaha 2 stroke DI. Come on Yamaha build it for '15!!!

With Yamaha's track record of releasing products, you'll never see it that soon. Unless it has already been in the making for the past 3 years like the viper has. Monoshock skid was supposed to debut in 2003, never came out till 2006.

Keep imagining things. If you think the "viper" has been in the works for 3 years, you are even more clueless than I think you are. The Procross chassis was always designed to take a wide variety of mills. It started back in 07.

That's a neat looking bike. I've read too many posts about the new, hi-performance, 4-stroke dirt bike motors being maintenance intensive to not believe it. I was in the market for a new dirt bike this summer to replace my 13 year old KDX 200. I was disappointed to read about how much maintenance the 250F bikes required. The 4-stroke sled motors are built to street bike standards and that's why they are so reliable. The downside is weight.
