I did a quick search first but didn't see anyone else complain about the stock mirrors on their FZ10. It seems that at high speeds the mirrors start to move and its really annoying. Anyone else have this problem?
I found these as well. Different look, same idea.These or something similar would do the trick:
CNC Black Billet Mirror Riser Extender Kit Fit Universal Yamaha Motorcycle | eBay
I really like mine too, I doubt anyone even familiar with the stock mirrors would even really notice the extenders, looks completely stock.I just installed these on mine and I am very happy (for now). They complement the existing mirror mount and look stock with the improved visibility (ofcourse).
