Hello,
I bought a set of suspension dirt cheap for a project. I believe it is from a Suzuki RMZ 450, but I am not sure. Can anyone identify the bike and possibly what year? Thanks a bunch

Looks to be around 2012. I Have the 2015 RMZ 450 and the years around then are air forks. Probably 2008-2012 spring showa.

October 2009

Shock looks identical to one I have sitting in my garage off a 2007

Thanks alot for the help guys. 

I get alot of different suggestions but  I found indications that the "6K 25" marking may mean that the fork legs are made in 2006, meaning that they belong to a 2007 bike. One 2009 has forks marked "8K". Can anyone verify? Does 450 and 250 forks differ? I don't want to buy the wrong spare parts 🙂

Bump

Still need your help, thanks

From what I can remember, The 07 and older rmz450 shocks have the smaller high speed comp assembly. In 08 and newer have the bigger hs comp adjuster assembly similar to a kit shocks.
If it’s an rmz the fork lugs will have the larger front axle diameter. 22mm I believe . End have 20mm

What spare parts are you looking to buy for them?

With a few exceptions all the 47mm Shows forks share the same parts
