Hi guys.does any one know if the rads from a 2009 wr450 will fit the 2011 wr , looking at the performance rads on EBay , but sellers only doing these rads upto 2009. Seems a good up grade at a bargain price. Any feedback on these rads would also be gratefully received ,many thanks Cliff. Sorry if this has been covered, I'm new!!!!!!! Have searched to no avail!
