Perhaps some additional infos that could be helpful to you as

there were factory optional softer/stiffer Titanium springs offered as well.

 

If the marking are still visible on the side of the last coil, here's how to ID them :

 

green stripes : 4.5kg/mm

red stripes     : 4.7kg/mm

black stripes:   4.9kg/mm

blue stripes:     5.1kg/mm

 

I have both a very slighltly used 4.7 and 4.9,

either they never had the colour ID stripes printed on or they wash/scrub off very easily.

 

(infos as per the 2010 YZ125 Service Manual)

Thanks again,Im asking all this.My bike 11 wr450 Revalved rear shock with YZ 08 250 spring(Whats supposed to be 4.9) No marking on spring,my bike not right.Too soft So Im sure they sold me 4.7 spring.Because My 07 Wr450 Same revalved shock same spec.That spring was in fact 4.9 bike was perfect.So I need to look for 4.9 Ti spring.Or try to get steal aftermarket spring.I the range of 5.0-5.1 Thanks again You dont have 5.1 for sale do you?
