I bought these bolts with my Easton EXP kit, and they are supposed to fit (and motosport.com) is still showing that they do fit a 2007 RMZ (250/450), which they do not. The bolt thinkness is too fat (will not fit through the rubber mounted cones) and the bolts length is too short, so you can't actually get the nut on. I have called Easton 2 times and up until today I have not seen anything that would allow me to mount these bars. However, I am seeing on easton's website that they have a new bolt kit number for the 2007 RMZ (TH 90 11.9 PN:2014735), which Motosport currently doesn't have. Anyway, I just wanted the RMZ owner to know so they wouldn't buy these and get frustrated like I have been. I just hope the new bolts will fit. The OD of the bolt appears to be the same, which IMOP still doesn't fit.
