they should. ktm sm wheels are same as berg but without the behr "Husaberg" insignia. Axle and bearings are the same. Check the diameter of the axle opening of your fork lowers as they may not be the same on the FE vs. FS bikes. Haven't owned an FE so I cant really say. But I understand the FS front axle diameter is the same as a KTM supermoto but perhaps smaller than the front axle diameter of their (and perhaps Bergs) dirtbikes.
