BDX claims 1.5 lbs loss on their website. What am I missing?
400lb proclimb, "can it be done" project
- Thread starter madmax
- Start date
I think all the BDX weight loss numbers are based on the 2012 model.
I was doing some figuring on some different future sled builds and thought I'd share what I came up with for weights and what it takes to get as light as you can with strictly bolt on parts that are available right now. Nothing custom or discontinued. I tried to uses as much published data as I could, either from this thread or elsewhere. I filled in gaps with what makes sense adding or subtracting from groups of parts I've seen weighed or my own personal experience.
The left two columns are comparisons of sled's I'd like to build for myself sometime while the right two columns have fewer personal preference items. I also did it with the 162 sled this thread started with and a 2017 162 Mountain Cat just to see how much of the weight savings we loose that Cat made on the sled when we start replacing parts. If you ride a 153 sled, take 5lbs off the totals and that's where you'll be. Start weights of the sleds are crate weights measured by the OP.
As you can see, it's tough to get that last few pounds to be sub 400 dry and still have a tough sled. It's also tough to build a boosted sled that's sub 400 unless you have 40k in the bank. If anyone can think of anything else that would be bolt on, I'd like to hear about it. Also, I have no affiliation with any of the companies listed on the sheets. Just my personal preferences.

Wow, that looks awesome. You must have a lot of free time at work. The 2017 MC 153 should be pretty easy to hit 400 since the weight loss in the 17' model.
I actually compiled it after work one night. I just try to do as much research as I can before spending my money. I was trying to figure out how to build a better, lighter sled than I already have and not spend too much more than what I have tied up in my '14 pro-lite.
Unfortunately some of the areas that Cat cut weight on the MC are irrelevant when we start replacing parts like the hood and can. 1/2lb in the handlebars, 2lb in the tunnel, 1-1/2lb in the rails, and 3/4lb in the engine plate for a total of 4-3/4lb savings that are left. That's why I did a separate sheet for the 2017 MC vs the 2016 sno-pro. You can see that for a stock motor sled, in the right hand columns, you can still make a 2016 sno-pro lighter than the MC when swapping the track to a X3.2 because the MC has a bigger front bumper and the evol shocks. I left the stock 3" PC track on the MC because I doubt people would change it out for a 2lb weight savings and the performance it already delivers. If you look at the far left column where the suspension components and bumpers are changed, then there is less of a weight penalty adding better parts since you are replacing heavier parts to start with on the MC. You really have to do a build sheet for the specific sled you have to know within 5lb of where you will fall.
Ideally I'd like to be able to get a new SE model and do a track exchange since I'd be swapping so many parts, but they don't offer that with the MC chain case and driveshaft setup.
My current sled was right at 540lb completely full to the brim on the 13.5 gal trail tank and burped as much as you could physically do. That included the spare belt, tool kit, muff pot, Hubbs/BDX/Cat bumper, PP skis, 15W all steel gear set in the chain case, and Evol X front shocks. Since then I've added a Ti can, belt drive, and track shaft. My estimate subtracting fluids, tools, belt, and muff pot out would put it right at 420lb dry for a 162.

I don't recall the exact savings (I have it written down but cannot find it right now) but replacing the factory powervalve setup (valves, cables and servo motor) with the STM piston style powervalves was between 2-3lbs.
I honestly think people are missing the boat with track technology as it progresses.
10lbs of rotating weight is HUGE! The track is where our drivesystem loses the magority of HP. Not the clutches, jackshaft, chaincase, etc....it's the track!
Camo is going to make us look at tracks in a whole new way in the coming years.
I'd have to agree. 10lbs less track weight is a big deal. Wonder how close to 40lbs they could have got it had they done 3.5" pitch.
The 3" inch power claw is a very impressive track but man a 10lbs weight loss is basically impossible to ignore. Changing drivers, sure is tempting to change tracks at the same time....hmm!!!!!
Track usa told me a 3.5 pitch 155 is 42 pounds
Good to know they are making the 2.8 in a 3.5 pitch. You replace a PC 2.6 with the 3.5 155 and you can have some really good weight loss. Avid making 3.5 drivers yet for the cat of Polaris?

Some of my track weights from last season. Unfortunately I only weighed 162's.
PC 162x2.6=58.4lbs
PC 162x3=56.2lbs
Camo 162x3.2=55.0lbs
Advertised weight new Camo 2.8x162=46lbs
PC 162x2.6=58.4lbs
PC 162x3=56.2lbs
Camo 162x3.2=55.0lbs
Advertised weight new Camo 2.8x162=46lbs

I'm really curious to see what the durability of this 2.8 track will be and if it will have the same performance across varying snow conditions as a PC track. No doubt a soft, flexible, 3.5 pitch track is going to work well in the deep stuff, but how will it do on set up snow? More spin/less bite? I guess we'll have to see this season.
Going from my 58lb 2.6 PC to a 46lb 2.8 has my interest though!
