Introducing All-New PowderTrac™ Running Boards, available exclusively on the 2013 Polaris Pro-RMK. Machined from extruded aluminum for incredible rigidity with 50% open area for awesome snow clean out and an aggressive grip pattern for boot traction. How do you think these compare to current stock OEM and aftermarket running boards?



Introducing All-New Lower Control Arms, available exclusively on the 2013 Polaris Pro-RMK. Tonight’s Superbowl Sunday clash will feature QBs with two of the best Pro arms in the NFL – now check out the arms on the latest Pro: Enjoy a 2 lb. total weight savings for the pair, with forged aluminum ends structurally bonded to steel tubing. This is the same lightweight, rigid technology that has been used in aerospace for years and was first introduced on the Pro-Ride chassis in model year 2011. How do you think even more lightweight, rigid components will improve the ride & handling of the current Pro-RMK?


Introducing the All-New Pro-Lite Seat, available exclusively on the 2013 Polaris Pro-RMK. Ride with more agility and freedom on a seat 5.5” shorter to allow easier crossover leg movements, plus the occasional Burandt hop-over. For mountain riders, trails can be a means to an end, but enjoy a wider, flatter area for more comfortable seated riding plus a bonus 1 lb. weight savings. Notice the trick aluminum seat support, and how about the first overhead view of those new PowderTrac™ running boards – does this sled look like something you would be willing to throw a leg over?


Introducing All-New Carbon Fiber Overstructure, available exclusively on the 2013 Polaris Pro-RMK. This new addition to the already light and rigid Pro-Ride chassis delivers even more mountain-friendly weight loss in the proven Polaris tradition of never compromising durability. How will it feel? A more lightweight, strong and rigid chassis provides what we call Rider Active Control - better weight transfer for a sled that feels even more responsive and agile than ever. But as always, you’ll have to ride it to believe it.


Introducing the All-New QuickDrive™ Low Inertia Drive System, available exclusively on the 2013 Polaris Pro-RMK. Here’s the recipe for an even more flickable drive system: Begin with a new, lightweight extruded drive shaft & new, lightweight brake disc. Tie it together with a new “Belt Drive” system and you’re talking 5 lbs. less effort each and every time you carve. We’ll leave it to the engineers to explain why reducing rotational mass by 21% pays off big, all you have to do is imagine how it’s even possible the Pro-RMK can be made more flickable than it already is.

$15K and it's all yours. I don't really know what it'll cost but I'm guess it won't be cheap.

[Old Thumper]

Don't tell Iggy I said this, but that's some pretty cool innovation right there.

[cardinalcabins]

I have always had a love/hate relationship with every polaris I own or have owned (and really I'm still too young to hate anything) I wish they would spend a couple years just getting something right and reliable before plowing ahead with all the "innovation".

[PolarisCobra]

I like the idea of the belt drive to replace the chaincase. As long as they have the parts spec'ed right, and it's realiable, that should be a trouble free, quiet system, that saves some weight. No more changing chaincase oil, or adjusting chain tesion.



Might make it more complex to change gearing, but that isn't likely to be something that I would get into anyway...

That looks easy. One bolt on top and one on the bottom. Done.

[MXZ800Girl]

It looks like lots of innovation right there. I'll still stick with the "old girl" though! I wonder how high tech sleds will get. I bet someday there is a sled that steers itself! Or with a gyroscope (is that the word?) for freestyle and flipping!

I have what might be a dumb question. Why are folks so concerned with weight?

Asks the lady sledder ...


Because a lighter sled can get farther up the tree.

[PolarisCobra]

As for the weight question, it's easier to get a lighter sled unstuck then a heavy one. For the mountain guys, it's critical, for a trail sled, not so much.



I agree that you could change the cogs with one bolt, but that will likely mean a different belt too, so it will fit. But it is probably still better with no oil.

Didn't Polaris used to have a direct drive system before, I think it was on the Sprint 340 no chaincase just from the clutch to the driven pulley which was mounted directly on the driveshaft? How come that never caught on?

so thats why?

They also used on the Indy Lites. One reason it never caught on is that you can not change the gearing. It was also very herky jerky feeling.

That extruded Running Board is wild.... Now, extrude the whole tunnel and make a super rigid platform for the sled.

Not much of a fan for drive belts, but HD has pushed the bike industry away from chain drive..


Yet, in the car world the better cars still have chains and the cheaper ones are running rubber belts to drive the cams.

You have always had a belt on the clutch side. I don't see why it would not work on the transfer side. Ducati has run belt drive cams since the 90's. They aren't exactly cheap. Although their valve train does not have springs, so the resistance is much less than a conventional valve train. Also, many high end CNC machines use that type of toothed belt to drive the ball screws with very good reliability under heavy load.

LOL!

That makes sense about mountain riders! I was thinking trail sleds!

[RayC]

Nice looking.
Will be fun to try out.

I think if a blower belt can hold together on a 3000 plus hp dragster it should be fine on a sled.

Just say it like this. Nothing like Polaris in my book.

[sledaholic]

Or this.
