The 4-stroke engine was said to weigh about 104 pounds and deliver 48 horsepower. While Polaris claims this is a “snowmobile only” design, we expect you soon may see a familiar derivative in a new “Sportsman-type” ATV 780 CC,

 

this sled was intrroduced at the dealers show in florida a couple weeks ago.

does anybody know how much the engine in the HO weighs in comparison??

can u imagine how much torque that thing would make, u could pull big loads with just a little throttle.

That was a direct quote i copied and pasted on here. 780! wow. it is in the snowmobile for sure, that is a fact. www.amsnow.com not sure if you can access the article without being a member?

 

Here's a little more from that peticular arcticle:


"Frontier: Polaris’ answer to Cat’s 4-Stroke comes in the Edge chassis with a Polaris-built 780cc engine that was quiet and seemed stronger than the Arctic Cat. It would pull the Cat in a long straight, but we doubt for this buyer that this will be very important.

Also seen was a single seat version, but Polaris may not offer this setup initially. The two-up is aimed at rentals and Polaris will have about 250 for consumer production as pilot build for next winter before entering into full-scale production. The test unit seemed okay but we believe that what we saw may well change significantly under the hood before we see it again.

Also forgot to mention that there are two pictures posted of this 780cc four stroke motor. If you want to see them let me know and I'll try e-mailing them.

 

Isn't this the snowmachine that Polaris announced on their website?

 

Here's another link to check out http://www.maximumsled.com/articles/...2/frontier.htm

 

according to the article on maximumsled the cylinders go up and down together. they must have large counter weights to smooth it out. they said that they can put the cylinders closer by having them move together.

i dont think they need a compact design for a sled, but they do for a quad.
looking at the engine it almost looks like a big single cylinder.

still looks like a tight fit

48 horse power is all. What a piece of junk. You can make 55 hp out of a 520 fourstroke(KTM did). ATV's need to get better motors not bigger motors, that is why i am getting a motorcycle.

 

Now you would have to be a hard core greeny to pay out who knows what money, for a 780cc sled that only pushes 48hp. You will be riding with people on 400 sleds that will blow your cab off! I think think every sled company would have to stop making 2 strokes and every one left over would have to be sold before people will be forced to get a low powered 4 stroke sled.
