Yamaha 4 strokes are the best! 2 guys we ride with spring ordered them, i will have side by side comparisons with my vector to see what is overall better.

In my newest American Snowmobiler mag (associated with AmSnow) they ranked the two side by side and the Jag came out on top. But, then again, what the Hell do they know????

It has such an insane price tag, i mean base model apex price is only a little bit more than the jag. Can you imagine how much the turbo version will cost when it comes out?

Well, they were comparing a brand new model with 125hp to a third year model with 120hp. Doesn't seem like it takes much to figure out which one they would like better. I can't understand why Yamaha hasn't put the triple in the Apex Chassis. I suspect this is coming next year along with a bump in power.

"Both pistons move in parallel but each side fires on the opposing stroke."
What does this gain? More torque ?

They also noted in the AMSNOW mag that they should have compared the new cat to the new Nytro.. not the vector..
THey also didnt give MPG statements or actual weights..
They also noted the vector was one of the best handling sleds on the trail..
Its funny how other brands give up crap because our 1000cc sled competes in the 500 and 600 cc two stroke classe..
Where does this leave cats new 1049cc sled???? in the 440 class LOL

That doesnt mean anything. All twin 4-strokes have the pistons moving in parallel. Remember that ignition needs to be spaced evenly, otherwise it would feel like a 2-stroke with a bad plug.srx70024 said:"Both pistons move in parallel but each side fires on the opposing stroke."

In fact, any straight 4-stroke with an EVEN number of cylinders will have PAIRS running parallel to each other.
So for the pistons to run opposing like in a two stroke, you have to have a 4-stroke twin run one cylinder, one stroke behind the other? For instance PTO is on is on compression (going up) while the mag is on intake (going down). The power pulses won't be 180 out from one another, but instead something else. I thought I read the Phazer motor was not of a parallel design.

In a two stroke motor, a cylinder will fire every time a piston comes to the top. So for a 2-cylinder 2-stroke, you have a plug fire every 180 degrees.
In a 4-stroke, 2 cylinder motor, it is common to have both piston run up and down in parallel. Therefore, while one cylinder is getting spark, the other is on the exhaust stroke. With this configuration, you get a power stroke every 360 degrees.
The phazer has a different setup. The pistons do not run in parallel, making a goofy setup. While one piston is at the top, the other is at the bottom. Therefore, when one piston come up on the exhaust stroke, the other piston is right behind it. So what you end up with is a power stroke every 180 degrees, and then 540 degrees of exhaust strokes. Think if it as running somewhat like a V-twin motorcycle engine. This is what gives the Phazer it's unigue sound.

Being new to the four stroke scene, why do the 120s and 150s compete in the 500 and 600 classes? Horse power-wise, they out class their respective categories.

Hmmm...I would think that any sane person would spend $10,000 on a 150 HP Apex, or less on a 120 HP RS, before a 125 HP Cat. If you want the best value and performance package in a 4-stroke, you have to put brand bias aside and admit that nobody does 4-stroke sleds like Yamaha.
But then again, if it's more expensive, then it must be better.

My bro-in-law bought the Jag. Looks nice so far, of course no seat time as of yet so final eval will have to wait. He was disappointed to find out after purchase and delivery that the sled has non-rebuildable shocks. Seems odd for a sled of it's cost.

Yep like the twin cylinder Honda's (Ducks) of days gone by.

The only thing intriguing about the Jag is the complete adjustability. I personally hope it works and is durable. That will push the other OEMs to bring it to the market in their own sleds, and it is an idea whose time has definitely come. For 90% of my riding I want to be down as low as I can be behind a windshield and out of the wind at 50 - 80 MPH. However, it would be great to be able to simply stop and move the seat, bars and windshield up when the trail gets rough. (which is next to never in Quebec.)
