Yeah looks like the site's changed - they now seem to be an official BMW dealer
From memory, the Fallert fender came with spacers to move the fender closer to the wheel, so it's not like it marries up exactly to the fork brace - the point being that I reckon you could use any universal 17" fender and make it fit with a little fettling
I saw that, and thought the same,there was a fibreglass one that fitted pukka, but i cant find the manufacturer, or a supplier either. i think the 17" conversion is my next mod.
