I was looking at the 15 wr250f the other day and thought wow I'd like a radiator fan on my 14 yz450f!! Mabe even a 6th gear. ...or a headlight!! I'm sure someone else has thought the same. Fits think I'd want to do is the radiator fan the fan itself doesn't look like it comes with a harness I checked the oem parts diagram and couldn't tell what I'd need.. would I be able to run this off the bike or would I have to put a battery on the bike?? And will they be making the wr450f like they did the 250?? Thanks!
