" I am in agreeance with Jay. Twins are for 90% of the people out there and the riding they do. "
Only because people no longer have a choice
"In my opinion, they would not be much better off than they are now if they built a triple.
The first reason is that the sled would weight more. Isn't this what we've been trying to reduce for the past 20 years? "
No. The reason the triple motor died was the constant harangue from the sledwhores (Definition: professional storytellers who get their stories published in slick, glossy magazines). THESE were the people constantly whining and sniveling about how a Mach Z or XCR simply could'nt hang with a MXZ or XCR-440 in the whoop-tee-doo's. If you have the older magazines, the sledwhores were always comparing the higher performance machines with the little zippies, rather than a comparison of the features that specific sled category had. Compare like machines, not disparate machines.
Weight is no longer the issue. Many sleds of today weigh as much or more than the older triples. That is a fact. With today's advancements in composite and plastics technology, the weight can be significantly brought down with an increase in strength. Just remember the funky non-plastic Pol used to make their hoods from? Hoods can be made from vacuum formed Kydex (just an example), now that would be much lighter and much stronger than from just a few years ago.
"I hear everyone using the argument of power to weight ratio with the triples because triples can make more power than their triple counterparts."
Uh...I think you meant "triples can make more power than their twin counterparts"? The triples will be smoother, due to more firing cycles than the twins, and yes, they'll make more H.P. Also, an extra cylinder allows for the other cylinders to be smaller=durability. Back when a 650 was about the largest thing you could get, it was due to the materials technology. When Nicasil came out, cylinder size began increasing, but a cylinder was still limited to around 300cc each. Now we see cylinders approaching 500cc, all because of the advancements in ceramics technology providing lubrication to the piston skirts.
It is a good argument, but it is irrelevant because after a certain weight, it doesn't matter how much power you have because the sled becomes all together too heavy to handle.
"People want something lightweight, maneuverable, and universal."
Please see comments on sledwhores in first paragraph.
"Those things are something triples did not do well at."
An apple versus orange argument, you are comparing todays twin against 10 Y.O. technology, doesn't hold water.
"The second reason is that it is still a two stroke. The EPA is breathing fire down the sled manufacturers' necks."
Incorrect. The EPA sets a goal, the manufacturer meets it. Polaris already did with their cleanfire tech. I have written before to look at Bomardier's Evinrude E-Tec. It is a 2-stroke and it is much cleaner than any 4-stroke tech out there right now, actually, the current crop of 4-strokes cannot even compete against it. Power to weight, and Bombardier knew exactly where to take it.
"I think the money would be better spent on the development of lightweight four-stroke engine technology."
Will never happen due to the inherent design, unless a turbo is added, then you argue against yourself with the "but it is irrelevant because after a certain weight, it doesn't matter how much power you have because the sled becomes all together too heavy to handle.", statement.
"While it is true that a triple will make more / more consistent power than a twin, that era is gone now and I don't think there would be as many people buying triples as it may seem.
We can do just about everything with a twin, that a triple of yesteryear could do."
If you compare todays twin against old-tech triple, but with the right mods to the chassis, you can't even compete due to more power.
"Best yet, twins are geared towards the riding style of most snowmobilers out there and that riding style being the corner to corner acceleration of the trails and the fast pace of the ditches."
Which is what power is all about yes?
This is an example of the flawed reasoning when asking for a manufacturer to "bring back" something. Old vs new mindset. I propose a 600cc triple using E-Tec injection technology and computerization to maintain optimum engine performance. I also propose a 1200cc triple using same. One geared for people who like lightweight machines or who do not have the body strength to control a heavier machine. The 1200cc will simply have slightly larger componenets, so will only weight 10-15 pounds more.
Along with this new tech, the same focus should be placed on the chassis using the latest in plastics and composite tech where applicable. The rest should be focused on solutions covering the weight issue, which can be addressed with better materials.
The problem is cost. A sled can be built with 130 H.P. at 500 pounds wet, but another cylinder adds mass in terms of the machinery and increased cooling necessary to accomodate it. The manufacturers can look at what mods are being done by the more successful modders out there and incorporate them, just like they are doing right now.
I believe a high H.P. triple can be manufactured that will weigh only a fraction more than the current crop of twins, if someone wants to do it. Apply the latest in technology to both the engine and chassis, and the results will be fantastic.
