250r front calipers on a 400ex?

does anybody know if i can put 250r calipers on a 400ex without too much modification? i would really like to have the extra stopping power of a 2 pot caliper over the 400ex's single pot. has anybody out there done this? does anybody make an upgraded caliper? also, who makes a high grade braided brake line?

Dont even waste your money on it. The rear is the only way to go. Changing it will give you more ground clearance. The single piston 400 caliper is the same stopping power as the 250r dual. But if you really need it Baldwin makes the piece you need for $200. Otherwise they wont fit. Mo
