I recently discovered I'd lost one of the bolts that attaches my R&G lower rad guard. I didn't realise that this was an OE bolt so I contacted R&G for a replacement. Even though they don't supply bolts a very kind chap is sending a replacement anyway. Not only this, he also sent me a link(posted below) for the 899 spare parts catalogue. Thought this might be useful to other forum members. Ducatiomaha 2015 899 by Ducati Omaha - issuu
