Le XR 400R sono praticamente tutte identiche, dal 1996 al 2005. Nel 2000 da bianche sono diventate rosse.
L'unica cosa meccanica che cambia è l'albero secondario del pignone, che nel 97 o nel 98, è stato aumentato di 1 mm sul diametro perché risultato debole nell'uso esasperato.
è possibile che nei vari anni siano variati anche i getti e le carburazioni, ma attualmente non abbiamo maggiori info.
