I am looking for a new rear brake pedal for my 05' WR450. I have been searching Ebay and found a new one for a WR250 part number 4XM-27200-00-00 for a good price. I have been searching through the TT OEM store and found that the YZ450 and WR450 use part number 5TA-27200-00-00. Does anyone know the difference between these two part numbers and if the former can be used on a WR450? Also, I have done some searching and have not been able to find an aftermarket replacement, does anyone know where I can find one?
