Why does everyone make such a big deal about sled weight?

I don't understand the obsession with each and every pound of weight on a snowmobile. I mean seriously, is there ANYONE here who can honestly tell me that they can tell by the feel of the sled whether the gas tank is full or almost empty? I know I can't, and we are talking about a difference of anywhere from 60 - 80 pounds!!!

So this crap about weight is just that in my opinion. Someone prove me wrong...
 

I don't notice the tank empty or full except by the display. I'm too busy going fast to even notice. Lighter would be nicer, but I'll take what I can get. Everyone needs conversation and complaints.
 
I agree QC. I would like to see the guy who can consistently tell the diffrence between a 510 lb sled and a 550 lb sled. To me, how the sled handles in the trails and at speed are more important. More often than not, its how the sled is proportioned and set up that determines how "light" the sled feels....not its actual wieght.
 
If you ride the tight and twisties or ditch bang it does make a difference especially if all the additional weight is over the skis.

absolutly ! when the tank is full I really have to fight the ski lift when it gets down to about 1/2 the ski lift is gone ! that 70 lbs up high DOES make a difference :!:
 
I cannot tell the difference between Full and empty..

But i can tell the warrior is alot heavier (especially top) than my old viper.. Probobly why i rolled it on its side 3 seperate times!! and i beleve the extra weight is why alot of us are going to the extremes to get rid of a push in the corners!!

Have a rider ride on the back of your sled and then have him get off... YOU CAN TELL A DIFFERENCE!!
 
Regardless on tank level, if the trail is hardpacked I always get ski lift in the corners. Maybe I need tractor weights to hold me down.

You are the first (and only so far) person to claim this. Not doubting you at all, but I think everyone else is pretty much making my point...
 
QCRider........I'm with you - I can't tell the difference in handling or performance between a full or empty tank of gas. Even in the "steep & deep" with a full tank of gas and a 2 1/2 kicker can strapped on the back, the sled felt the same. (I use to ride RMKs.)

Artic Crap's advertising campaign a few years ago made a big deal about horsepower to weight ratios. Yes, horsepower to weight is an important ratio, but come on. My brother rides an 800 RMK with a SLP pipe and a boost bottle. No doubt, his sled is pushing 140+ HP and is lighter than my RX1. Nevertheless, he cannot high mark me nor is his sled any faster on the trails. (This really pisses him off.)

Ask anybody who thinks the RX1 is a heavy pig if he has ever ridden one. Thus far, everybody I've asked says no.
 
I was pi$$ed off about the many issues with my 03, but it never felt heavy. Heavy is any sled stuck in a trench with a track full of wet snow... or any sled upside down in powder at 10000' because you didn't make the turn with enough speed while highmarking.

My point is, handling and ride were my issues. The handling was tunable with $$$ and not a weight issue, the ride was an issue. Any weight sucks when your stuck.... There is no substitute for HP and torque.
 
I can't feel a tank of gas, but I *can* feel a tank of gas + 130 lbs. My old sled is about 430 *with* a gallon of gas (stripped from 460 stock and very dry). Definitely lacks something in terms of HP (87EX ~100-105), but that sucker is EASY to throw around. In comparison to RX1, 555+gas = ~650, looking at a gain of 220 lbs, which is more than 1.5 times!

** With my weight added, they are spot-on power to weight. This meant that when the RX1 had 121" track, the Exciter could kill it out of the hole (because of inability to apply track power efficiently with too-small of track). Does that mean it could beat RX1 to 1/4 mile? Nope. Couldn't even take it to 200 feet.

The problem with using power-weight as a measure of performance potential is that it doesn't account for FRICTION. Regardless of horsepower or weight of vehicle, the friction is constant - thats because they displace the same amount of air and have the same length of track and sliders. Unfortunately, friction starts to build IMMEDIATLY, and increases EXPONENTIALLY as velocity increases. Once you get any sled to ~100 mph, the overall friction level in the system (internal and external) drains about 100 hp (in excellent conditions). Every subsequent increase in hp creates a lower increase in speed - it takes an additional 40-50 hp to increase velocity by 10 to 15 mph.

DON'T take this to mean that p:w is irrelevant, just that its impact is not nearly as much as some people would lead you to believe. The extra 220 lbs on the RX1 let a much weaker machine that is 16 years OLDER beat it to nearly 200 feet. As the friction builds up, the smaller engine has a harder time accelerating the vehicle, and the one with more horsepower overtakes it. It'll fare better now with the 144", but the old sled will still dominate in the first 25 feet, and there is NOTHING that can be done about it.
 
Racing has never been my concern, kicking a$$ on the trail is. I don't believe the weight of this sled was the problem, set up was. The power is increadable and deminishes the weight.

Not anymore.
I find it pretty easy to tell the difference, and the rougher and twistier the trail, the easier it becomes. I find myself sitting way further forward with more than 1/2 a tank of gas, on tight trails so I can lean out quicker and further.
