Sorry dude i dont know, it just came with them from the guy i boght it from. it has the yss logo under the red bull cans.
heres an old pic of the bike it has the same shocks, just no cans over them it also have the logo under the spring. they might just be stuck on some cheap shocks tho. but i dont realy mind either way
