if u go to a 1.25 then you will lose top and hp but u will have alot more traction. they recamend going to a 1 in from a .75 in cause u wont lose any hp,top speed and still have plenty off traction. just my 2 cents

For under $40. more like $25. you can get a decent aftermarket top gear, drop 1 or 2 teeth off in size and you'll more then make up for the track difference, you might lose 2-5 mph on top end but boy will she leap and dig out of the hole, by dropping the tooth/teeth your making up for the extra hp it'll take to spin the bigger track with gearing. Its a real easy thing to do with minimal amount of tools and boy will you be happy with the difference it'll make. Its a common well recommended thing to do when going with a deeper lug, also keep in mind much more then 2 teeth less on top gear and then you'll have to replace the chain also. Here is gearing chart for ski-doo so you'll know what its currently geared for and what you'll be gearing for as far as top speeds. ski-doo snowmobile forums -

I'm running a 2" on my 2000 440 MXZ 121" with no noticeable problems. Few minor upgrades (shocks, ported and polished heads) to give alittle more umph, but no problems as far as climbing or trail riding.
