Just an idea, i was thinking maybe I could loose a few pounds of rotational weight by switching to a lighter weight track. I'm currently running a Ski-doo 121 x 15 x 1.25. Does anyone know the weight of this track? I'm not willing to loose the 1.25 lug. But is there a lighter track out there that performs the same?

im not sure what yu track weighs but maybe a camoplast would be lighter, they are good tracks.

Ski-Doo tracks are made by Camoplast.
Switch to the 1.25"lug "Ripsaw" I'm not 100% sure on weight reduction for the 121" but for the 136" it's alot lighter.
Just a guess but I bet its the same for the 121".

I suggest looking at Bombie's parts and accessories cataloge. It has all the different tracks they carry at the dealerships with their corresponding weight. I beleive most new camoplast 1.25 X 15 X 121 tracks average 38.3 lbs. You can find a lighter 1.25 track (Rip Saw model C9921H) that is 36 lbs. That track even has avery third window closed! More potential weight loss... There also no harm in punching out a 144+ stud pattern and not putting in the studs. Last but, not least are light weight clips. If you have some extra BON$E, order those titanium clips that Specialty Sleds carry. I think there may also be some new alumium clips that have holes in them but, I dont know who makes them? You could probably trim that track down to 32 lbs or less. Personally I would start with the 1.5" cross country track (model C9803C) that only weight .6 lbs more....

Good luck

I have a 1-1/4 track myself,but was debating on studding it. 144 up the middle,but don't want to lose 10 plus mph on top end.I realize there's a give and take but I still not sure if i'm going to stud.Anyone else stud a 1-1/4,and what top end numbers are you getting?

The track i'm running is the Doo/Camoplast #504151815 Gas man I found it in the catalog and it is 38.3 lbs. Now i have added 144 Woody's studs with aluminum backers, i will not remove the studs. The season before last i was running the Doo stock .875 with 192 Extreme stainless studs with plastic backers. I had a lot of them that tore out. I don't know if this was due to the stainless stud or the plastic backer. I have not had 1 pull out with the Woody's but i have broke a few (i would rather replace a stud) then have them pull out. Do you think i would gain any with plastic backers vs: aluminum? This sled is mainly for trail/ditch use.

Motor'n- top speeds with the 1.25 and 144 studs are around 95, maybe more but I have never really held it open for that long. Also keep in mind i'm geared way low 23/44. If it was top end i wanted i wold have left the .875 on it. Top end is not important to me. But it sure does get there fast.

Man, if it's traction and safety you want on the trails - Don't even worry about your rotating mass. Enjoy the ride! Stop and observe the view and wildlife. Stop and talk to your riding buddies.

But, if your lake racing and top speed is an issue, then yeah, 86 those studs and lighten up your track, put in a big wheel kit, loosen your track and add some extroverted drive sprockets, add extra bogie and idler wheels to reduce resistance, and line up your driveline and track to the "T".

It's all "give and take" and it's hard to find a happy medium. Good luck...

If you have the 3rd window track you could also drill out the window where a clip should be. I did this last year not for weight reduction but to let more snow in, it works but I will take a fully clipped track anyday.
Find a 1 1/8" hole saw and pop them out in about 15 minutes.
