It may be cheaper to source parts in USA, try thumpertalk or advrider search.
At the least try and get part numbers and price genuine parts from a Honda quad dealer.....
I have found this website that is quite helpful, might help others out if they XR650. Got a very good friend of mine who works in a Honda dealers, and he is now pricing all the bits up for me, will post prices later for how much it comes in at. And part numbers if anyone wants them.
