In person they look a lot shorter than the xx's shocks but I haven't taken a tape measure to them. That would be funny, at the yamaha shop guy says "sir can I help you??" I'm all like "no thanks" as I measure the shocks lol
The regular yfz450 shocks are about 16" (2009 and back). The new FI yfz45R shocks are about 18.25". You would have to modify a bit like on the DS shocks. The new 450R shocks are amazing, they hi and low compression adjustable, rebound and preload. They are comparable to aftermarket shocks like Elka.
u have to mod the ds 450 shocks by grinding some off of the top eye and a tiny bit of the frame but nothing major and alot of people have done it.
the reason i was asking about yfz 450r shocks is because there cheaper on ebay than ds 450 shocks.
so with the yfz 450 shocks u have to do the same abount of modding as the ds 450 shocks but they will work???
this is a email i got about our shocks fitting different bikes dont know if it helps keep in mind this email is about fox float x evol fronts
Your current shocks will fit stock shock length Polaris Outlaw front, TRX450 & 700XX plus KFX450 front the only difference is the spacer will have to be changed in the top end eye for the Outlaw and KFX you need to move the bottom end eye spacers to the top and buy a new set for the bottom.
