9R 146 gearing

[Klutch]

I'm 240lbs before I put my gear on. I have a 146 because when I snowchecked last year, it's all I could get. I wanted a 155 and will likely snowcheck for next year. So I'm wondering if there is much advantage to gearing down the 146 for the year?
I figured I'd leave it and clutch it better this year. Maybe the higher gearing is an ok situation for the short 146 track?

what gearing did it come with. I just picked up a 650 146 and it came with 22/43. i would also like to gear it down to at least the 22/50 qd2

Why not put 155 rails, and track, on the 146?

Might just need clutching adjustment if anything. Give it a try and see how it feels.

FWIW- I have a 155 skid from my 22' Khaos Matryx Slash that has 350miles on it that I'm not using. PM if interested.

I beleive mine is too.

I'm torn about doing that too. Just don't think I'd keep it longer than this season. But it's a possibility. Need a skid or rails, track, drivers, and gearing. Just not sure if I want to buy all that and then dump the sled next year.

I would be interested, but I'm in Canada. Not sure you'd like to ship it here?

That's what I did. Gearing clutching, the whole works. I went with 25 63 tki gearing. If you sell your sled. Put it back to stock and put your better rails, track, clutching and goodies on your new sled.
From here on out I'll be buying nothing but 146s and doing the 155 mod. It's a little more money than just cutting a 155 but you get a bigger cooler and nothing is permanently altered on the sled when you're done with it and it's back to stock.

...you get a bigger cooler...

the bigger cooler is significant. i would say it is 8" past the end of the seat.
why they don't put that one on the bigger track sleds is beyond me

It appears all 146s have quickdrive 1, which would be 22/43 - just from a quick look at the specs on Polaris's website. I'd be surprised if gearing down was a step forward for a 9R/146 - it should have plenty of power to keep the clutches in their ideal range in deep snow. I'd agree with the suggestion to do a little clutching and leave the gearing stock. I'd think a 650/146, on the other hand, would absolutely benefit from QD2 gearing. All that said, before you commit to either snow-checking or swapping the track and skid, it's worth seeing how you like it at 146. I only see maybe 1 out of 5 days with really good snow where I need lots of track (I'm a slimmer type though). Shorter tracks have a lot of fun factor until you need the longer one...

This is exactly where I'm at. Rode the 146 last year and loved it other than when it was too short for the snow. Really torn about doing anything. I now have a guy that wants to buy it and my dealer has a 2024 9r 155 if I do sell.

How did the 25/63 gearing work for you ?

It worked well for me. I can still go lower if i want. Tki makes a 24 top sproket. I still may have to add a gram or 2 in my primary. I'm running a 153x3 power claw though. Throwing a 300lx on this season and have a punched alpha track I haven't tried yet. Will run those first before I change anything else.

I have a 23 9R Khaos 155". I absolutely love this machine. However, I rode a buddies 146" 9r last year, and it is a riot. Part of what makes it worthwhile is the taller gearing. The 9R accelerates so much faster in the shorter track version, it makes it able to climb most places my 155" goes. The faster track speed makes that possible. The 146 is off the ground as much as its on the ground and is much more playful. Don't change a thing until you ride it, and then decide for yourself. After riding one last year, I snow checked one for myself.

I also like the 146” better, more balanced and faster trackspeed. Had both 146 and 155 last year, the 155 is to be replaced by a 9R in 146 as soon as it shows up. The 2024 has also real drivers finally, that’s been the only weakness.

 

[NiklasE]

The biggest reason why the 146 have qd1 and 155 and up have qd2 is because of the pitch and size of the drivers. 146 have got smaller drivers than 155/165. 7 tooth 2.86" on 146 and 6 tooth 3,5" on 155/165.

qd2 with 7x2,86 will be very low gearing, about 5% lower than a stock 155/165...

 

[kanedog]

qd2 with 7x2,86 will be very low gearing

incorrect. The gearing is actually quite high. That is why there are gear down kits available instead of gear up kits.

 

[Klutch]

Would 7 tooth drivers not be a taller/ higher gear than the 6 tooth?

 

[damx]

Yes if both had the same pitch. But the 146 track has a 2.86" pitch. 7t drivers.
The others are 3.5" pitch 6t driver or 3" pitch 7t drivers.

Yes you are correct, but qd2 + 7x2,86 is the lowest gearing you can get with polaris parts. There isnt any stock polaris sold with that low gearing.
