The brake line itself is all the same. You can use Harley lines. You just use the stock banjo bolt which I think is 10mm. The harley braided line that aftermarket companies sell use either a 8mm or a 10mm Banjo opening. If you do use the harley line make sure you use the 10mm banjo opening bolts. They come in a few bends, either straight, 90 degree and 45 degree angles. I think the stock BA/SM uses a 90 bend banjo opening on both ends.
