weight to hp comparisons 2012 cats vs 2012 RMK

barry1me · Mar 12, 2011

So AC is not letting the cat out of the bag on the 2012 weight sleds. The only thing they say is the 2012 M8 is the same as the 2011....that puts the 2012 M8 at 468lbs dry. I may be a bit cynical on AC not showing weights for there 2012 sleds but I compare it to online dating....Theres a reason why the pretty girl in the add doesnt give her weight:face-icon-small-win

I also found this spec sheet http://www.arcticcat.se/source.php/1346845/arcticcat_snoskoter_2012.pdf

That gives the weights on the 2012 AC sleds in KGs....granted this isnt for the US, but the numbers they give when you converter KGs into LBs align with what AC claims the weights to be for 2012 on the M8. I like the look and what AC is doing with there new sleds....I think they will sell pretty well.

2011 M8 153 163hp 468lbs 2.87lb/hp
2012 M8 153 163hp 468lbs 2.87lb/hp $12,400
2012 11T153 177hp 548lbs 3.36lb/hp $14,200
2012 RMK163 152hp 438lbs 2.88lb/hp $11,999

Might as well use the Pro 155 instead of the 163 since you are comparing it to cats 153s..

2012 RMK 155 152hp 431lbs 2.83lb/HP $11,799
2012 M8 153 163hp 468lbs 2.87lb/hp $12,400

And..HP per lb.

Using wt numbers from the above pdf..converted via Google.

2012 RMK 155" 152 hp 431 lbs 0.353 HP/lb
2012 M8 HCR 153" 163 hp 469.58 lbs 0.347 HP/lb
2012 M8 SP 153" 163 hp 473.99 lbs 0.344 HP/lb
2012 M8 153" 163hp 476.2 lbs 0.342 HP/lb

Just to correct lb/hp numbers with AC's claimed wt from above pdf.

2012 RMK 155 152hp 431lbs 2.83lb/HP
2912 M8 HCR 153 163hp 469.58lbs 2.88lb/hp
2012 M8 SP 153 163hp 473.99lbs 2.91lb/hp
2012 M8 153 163hp 476.2lbs 2.92lb/hp

But, we all know the math and numbers don't always directly apply in the real world..so its all moot...

Like, for example, how could a 140 HP snowmobile even run in the mountains? I mean really, 140 HP, that won't even work to ride the trails at elevation...sheesh...

I thought for sure Cat would have came up better for it's 50th and to compete with the Pro. Kinda disappointing.

Dam Dave · Mar 12, 2011

OK but to be fair, Cat lists CRATE weight not DRY weight, crate weight includes all fluids except injection oil and gas, engine and drive train are ready to ride

Dry weight would be lower

trevormezz · Mar 12, 2011

heavy

come on 568 punds! THAT IS SO HEAVY ITS REDIC! CAN YOU SAY 05 06 POLARIS 900 RED ROCK! THAT THING HAD 165HP AND WAS A TANK. LIGHT WEIGHT IS THE WAY TO BE IN THE MTNS! THE NEW TURBO IS GONNA WIN A LOT OF GRASS DRAG RACES IN MT BUT WHO CARES CLIMBING AND SIDE HILLING NOTHING BEATS A PRO!!!

MNIQR · Mar 12, 2011

Being a bit of a hobbyist statistician myself, I would like to add another variable to this discussion....that is; ugliness factor.

I will go further. Who the dark would want to ride such an ugly pos? And no, I'm not joking.

And I'm not a brand guy either.

Ti oil tank 2 smoke is injection oil, 4 stroke is dry sump tank

Good point.

So, would this equate to 15# even? More? Less?
Coolant would be the biggy, I can't see chain case oil amounting to much, 1#??...could be wrong?
Shock oil, again 1-2#?? Wait, Cats are all air this year, so shock oil is moot...

Honestly, I'm by no means a fanboy, I was ready to own an M8...I want to see Cats new chassis and engine work. I just enjoy number crunchin for the hell of it.

I actually don't find the sled all that ugly.. But, every "new chassis" / sled is ugly at first, generally. Rev, XP...ok, so the F chassis cats are still HORRID.. but you get the point.

Dam Dave · Mar 12, 2011

hmm, I dont know, 8-10 pounds maybe? DD is 15 ozs of oil, antifreeze would be the rest, does brake fluid count?

m8sandman · Mar 13, 2011

i was looking at the chart, don't see anywhere where it says the weight is "crate" weight??? maybe some of our euro friends can confirm...

snowmobiler · Mar 13, 2011

141.2 hp @ 7900 RPM
143.2 hp @ 8300 RPM

for what its worth, thats how they were advertising the weight of 2010 and 2011 M sleds, if you snow checked they guaranteed the "crate weight" on delivery

my 2011 M8 SP 162 was 467 I believe

m8sandman · Mar 13, 2011

know my 07 M8 with a fifty pound weight loss and tons of mods was no comparison to my pro STOCK, cat better hope that chassis can make up for it. was hoping the new cat would bring me back, took a lot after being a cat guy for 15 years to switch, still wearing my ac gear

if the cat was the same or less in weight i'd be all over it but couldn't see wanting a heavier sled. plus the pro flat out works, by far the best production sled i've ever ridden...

Dam Dave · Mar 13, 2011

dont know, Pro weight is dry weight how dry? M8 crate weight has fluids how much are the fluids?

guys were weighing the pro's right out of the crate and got the same weights polaris claimed....431 for 155, 438 for a 163...so the weights are right.....and those are right out of the crate, all fluids full except oil tank has about 3/4 of a qt. in it fuel tank has about 1 gallonin it, so you would add almost 3 qts of oil and 9.5-10 gallons of gas ready to ride...
