Has anyone looked into changing the entire front from the spindles on out on a Foreman 450 with the spindles and disc brakes from a Foreman 500. It looks as though Honda just redesigned the spindles to have two tabs to bolt the calipers on. The geometry of the two spindles look the same. Same caster angle and ball joint attachments. It appears the tie rod ends bolt up in the same place. Honda mechanic, any thoughts. Is the bearing and /or half shaft diameter different between the 450 and 500? This appears to be the only place where you could have problems, if the 450 shaft would not fit into the 500 spindle.
