My first message seems to be slightly corrupted. It is my understanding that Yamaha in Italy, assembled 300 WR450FS models and then distributed them to specialist markets around the world. The WR450F(S) is the 2004 model. The assemly job took the form of 300 pre assembled Pump and Motor kits supplied by Bosch Rexroth. Further information is available from my posting and parts list request in the 2004 Yamaha WR450F 2-Trac posting. Regards Phocks (phocks@wn.com.au)
