Hello, I would like to buy the Wunderlich risers for my RS. Has anyone bought them directly from their website? I saw that they have two options, one for 79,90 and one for 99,90 http://www.wunderlich.de/shop/en/wunderlich-handlebar-riser-1.html http://www.wunderlich.de/shop/en/handlebar-riser-abe-approved-3.html As far that I can understand, one is for rising the bars without the NAV support and one with the NAV support. I have the NAV support on my RS so I guess I have to buy the 99,90 version? I don´t want to buy something that will not fit perfectly, so I hope you guys can help me. Thanks M.M.
