Gear combinations for Pro RMK

[SpeedWobble]

Has anyone checked to see what gear combinations will work in the new Pro RMK chaincase (with the stock chain)? Stock appears to be 20:42 and I would like to try 19:43 gears. Just curious if anyone has looked.

Thanks

Have you run your sled yet? I was thinking I would gear down, but that sled really pulls hard down low. I think it is the combo of a good skid setup, lightweight sled and strong motor. I doubt I will change mine.

i've changed mine to a 19/43 and changed the track to a ce... i will let ya know after this sat.

Did you change drivers also?

Yes 19/43 works with the stock chain.

Does it look like there is enough room for a 46 bottom

No, I bought a 2.86 pitch ce 2.5 fits just fine.. but i do have a set of avid 7 tooth drivers if i dont like what the track is doing in the tunnel..

 

[D700]

I don't believe a 46 would fit.

X2, i only got one 22 mile ride but the gearing seemed pretty sweet stock. had lots of low end snap and grunt...

7 tooth driver has too small dia. track will rub on chain case!

Does anyone know what gear combinations the '11 RMK Assault got?
Does it have a lower stock ratio then the PRO RMK?

For example;
RMK got 42/20 (42 divided on 20) -> ratio = 2,1
Assault got (I dont know the true numbers) 42/18 -> ratio = 2,33

Higher ratio = lower gearing = faster acceleration, stronger and quicker ride?

Am I right?

came with 20/42 on my assault

Very interrested in how it acts when putting 19-43 gears in!!? Have you tested the sled with this setup? I got my Assault 155 last week and I am overimpressed about how strong this sled is...was also thinking about gearing down before I got the sled but...low-mid range on this thing really is SNAPPY! Wheelie machine! Running 10-66 weights 8300-400 rpm at sea level..need to put heavier weights in I think.

My Assault Switchback with the snowcheck 2" track came with 20/42 gearing, just throwing it out there.

gearing

is it safe to run 19 - 42 ?

 

[NapaMatt]

you could run those gears..

have u rode it yet??


It RIPS with stock gears!!

mine is staying stock!

 

[srosscojw]

NOT YET

Nope not yet but I have put the 2.5" CE in it already and will gear it 19-42. I could not stand the 5.1 track in the dragons.

 

[Ask Yourself]

19/43 rocks. CE 2.5 track rocks. Tied clutch 73-57.46 w/red/blk sec spring with stock prim. spring w/ 10-64 runs 8200 all day long.. run 6000-8000 feet.. This YEAR is going to ROCK...

I have 20/42 in my assault.
I've put 10-68 weight, (Sea level)
it pull very hard. It runs +- 8150 rpm.

How fast this engine should be?
