will a seat from a 08 yz450f fit a 05 model?

it should. i don't think they have changed the design that much.

I think it will as well....

it doesn't. too short, and the rear mounting tabs are in the wrong spot.

if anyone needs a all black seat for a 06-09 yz for super cheap, hit me up. its in mint condition

really?! wow... thats strange.
