Although every Spyder up to 2013 used the same front fenders and supports, the 2011 and 2012 RS was the only bike that used spacers on the front fenders as the front was narrower on that model. 2010 late production RS models also had the spacers. In 2013 and up there were 2 fender options but there is no spacer on those models. For our wheels to fit removal of the spacers (#55a) is required. Please give us a call or email if you have any questions.
