07 YZ125 Shock on 06 YZ250

I have the chance to get a new 07 125 shock for the same amount it would cost to have the 06 250 shock serviced, are the shocks the same with just different springs? this is what im hoping, and that some of you suspension tuners know! Cheers Andrew

think the valving is lighter on the 125

Could anyone confirm this? i need to move fast if im going to get this shock, the other option is to have my stock one serviced but it will cost slightly more.

If it's to soft then you will have to pay for a revalve so be better to get yours serviced

the compression is actually stiffer on the 125 but the rebound is lighter, the light rebound will cause problems on the 250 spring.....

Thank you mog thats very helpful :thumbsup: What would happen if the rider in theory of the 125 was a tad heavier and needed a stiffer spring? Would he need a rebound also?

Would you suggest against buying the shock then?

I think the 125 compression stack suits most riders other than very light ones , but the rebound stack needs beefing up , Its tricky as you would be paying twice ...is there anything wrong with your shock ?

It hasn't been serviced for god knows how long and im just trying to do things as cheaply as poss, i guess its cheapest to just have the old one serviced. Is there anyway to tell when it should be serviced or should it just be routine, i can do the forks myself but the shock is not something i want to have a go at myself.

IMO they are the same stacks for same year models. 06, 07 and 08 all have different stock stacks. 08 and newer are all the same.

if its just a service then you would be cheaper to use your old one, as valving can be changed on both of them.I only recommend 25 hours on a shock or fork so it sounds like you are way over on that, you can strech a service to 50 hours if you are not a expert rider but thats IMO the limit.

Yes it looks like im way over that, Jayman seemed to think 125-250 may be the same for year to year, do you have the stack info for the 07 125 and 250 so i can compare? Thanks you've been a great help :thumbsup:

the 07 and 08 yz 250 was the same but the 06 250 was different, so it looks like they stopped changes after 07 on the 250, the 07 125 stack maybe the same on the 07 250 but the 06 125 and 06 250 were different so i suspect the 07 125 and 07 250 are as well.

Is there anywhere online where i can view the shim stack specifications so i can compare?

If anyone can tell me the shim stack specifications for an 07 YZ125 so i can compare to the 07 YZ250 Specs mog uploaded that would be great!!

do a search for valving database by kevin, that has lots of stacks for std bikes.

Thanks did a search but they dont list the 07 125
