alot of people say the 450r shocks are a bit too stiff, and since the 450r and 400ex have similar front ends, i think it would also be stiff on the 400exOriginally posted by HalfAquad
There way better than stock. You can adj them to be rock hard or adj them to be soft where you get to much body roll in the turns.
A 400ex with yfz450 shocks vs a 400ex with 450r shocks, the yfz450 shocked 400ex is going to handle the jumps and turns way better. With MX tires I had my ex dropped to about 6" for mx.

yea i heard they are really stiff unless you get them revalved/resprung and they also raise the ride height.that is why i went with the yfz shocks and there alot cheaper than the 450r ones.

Someone should fab up an upper mount adapter that slides into the original shock mount and clamps to the frame tube. It would lower the shock and raise the ride height probably 1.5", and you could make it wider so that you wouldn't have to modify the shock to make it fit. Something like this:
'00 416ex -- 11:1 Wiseco, stage 1 HotCams, LEXX slip-on w/ modded header, ASR +2 arms, 450r shocks, G-Force axle, FST style cooler, Trail Tech bars and clamp
Temporarily retired from my extremely short (but successful) racing career.
Maybe some IXCR in the near future.

With stock A-arms the yfz shocks are good. After I went to +3 on the 400ex the shocks where 100% total crap. Use yfz450 shocks with stock A-arms ONLY. If you want to go mx wide do it the right way with good arms and shocks. If you go extended A-arms and use yfz or 450r shocks you mise as well also run cut shock coils and run wheel spacers because it will be a total crap set up any ways and will do nothing more than make you look like a race quad when it realy handles like a total pos.
hmm. i must have magic YFZ shocks cuz mine is 200% better than it was stock.If you go extended A-arms and use yfz or 450r shocks you mise as well also run cut shock coils and run wheel spacers because it will be a total crap set up any ways and will do nothing more than make you look like a race quad when it realy handles like a total pos.

that would be a great idea, but like said b4 i dont know if it would be strong enough, maybe it is possible to make it strong? but the most important, would the suspention geometry work the same? the shocks may be a bit to angledOriginally posted by F-16Guy

you make no sense the yfz shocks are good, longer arms would be more harsh on the shocks and be more prone to bottoming out but the yfz450 already has a pretty good length front a arm, so these shocks can handle it easy.Originally posted by HalfAquad
