Getting the bike ready for erzberg, just finished installing a ktm 300 fan kit. All in all it fit fairly well. Had to file down the lip on the side of the rad, didn't take much, maybe 1/16". Rad kit was designed to be mounted at top of rad as ktm's don't have the down pipe in the middle just a connecter pipe on the side. Replaced the lower rad hose with a piece of steel braided pipe as the original has gone very soft with the heat. The rad guards are mecca systems and seem very strong.
