Rode against my buddies "new" '03 900 yesterday. About 2' of powder with a crustier layer underneath. I pulled through a moderate climb with sled at 8000 rpm and got stuck up a steeper section. His 900 blew right past with ease. This happened twice. On a bigger hillclimb, he was two to three sled lengths above mine. I thought an M would easily beat a 900. Here are the numbers: '06 M-7 LE (135 hp, 162" track) - about 565 lbs. wet or so. His 900 (150 hp, 151" track) about 595 lbs. wet or so. I am 25 lbs. heavier and had a 15 lb. backpack. Just by the lb/hp numbers, and just using bodyweight difference, I am at 4.48 lb/hp. He would be at 3.97lb/hp. Alone this is quite an advantage for the 900. However, I thought the extra track length and geometry of the M was supposed to make it "go" better. Could clutching be an issue? Or is it just straight pounds per horsepower in this case? Any thoughts? Thanks.

a well set up 900 can cause alot of fits to a lot of things.
i have a 900 and my wife has a m7 and i have rode each to there limits, the m7 is a freak for it's displacement and having the dd is good but it is hard to beat the 900.
summery is if they are both set up well and the rider is the same with my experience the 900 will get the 7 every time so even with the new chassis it's hard to replace the displacement. at the end of the day the guy on the 900 will be beat and the guy on the m7 will be ready to go out dancing for chicks.

take it to the trees or some sort of other technical type of riding and you will probably beat him. but on a straight up hill climb im not surprised one bit you got beat by a 900 cat. those mountain cat 900s are hard to beat with anything in a straight up climb. the M chassis is more suited for boondocking and such. thats my .02.

Got power
Get a M1000 and then go play,i had a M7 with a 162 and my bud has a 900, in the boondocking i have him but the hill was a little harder, if its not to moded then u have a chance,mostly rider if its stock 900

Went up this weekend, Ended up climbing a steep hill with some others, Yamahe RX1, Skidoo REV and a 900 POO with a 166 When all was said and done they wondered if the 151 was a mod 1000 or larger. It just gains speed from the base of the hill to the top with skiis in the air and half *** out of control. Gotta use body weight to control, But like said it wears you out at mid day! It is a little modified being 47 lbs. lighter. But engine is stock as a rock!

M chassis is better no doubt! especially for technical stuff. The MC/KK chassis isnt bad by any means but the torquey 8/900 big block is one of the best motors ever put into a sled from factory IMO!
There have been a few 900 cat motors (with monster big bores) in the M chassis that some big names in the business have said one of the best setups money can buy!

A half decent setup 900 will have way more low end grunt. And are you certain the m7 is running at par? If the m7 was geared down just a lil it would catch up better. Bottom line 700-900. Switch riders and see if there is a difference.........
I am thinking that one of these engines need is a siamesed cylinder head like all the new engines. I think it would take a lot of pressure off the crank and bearings. Rigidity is what they need! Explosive powerband if you ask me, Just reaks havoc on the bottom end! But FUN, FUN!

I ride with two m7s the only diffrence in the two is tracks. One has 162 other has 153. 153 wins every time every were any snow condition. Riders are very close in weight.
S
Track speed, Id say thats why the 153 rocks........
Could a 162" M7 benefit from shorter gears say 54/66 as opposed to stock 57/63 and actually do better than a 153" M7? Not to hijack the thread, just curious...
