rear disc 03 450 for 99 wr400??

anyone know quickly if itl fit? i know in the manual the outer diameter ir .5cm more but is the inner diameter to mount to the hib the same?

The 99+ rear hubs are the same. So the rotor will fit. It is larger -- 245mm vs the 240mm on the 99-01 bikes.

excellent! thanks for that!
