I’ve unfortunaly forgot my key on the bike ( that’s what I think ) back in september. The bike was fortunately lock to a post.. I didn’t want to run the risk of having someone else with, potentially, the key of my bike so I went to my dealer and ordered a whole new set of keys and locks. It set me back by just over 230€ + labour.
Make sure you’re covered by your insurance. Mine was fortunately covered by my credit cards’ insurance.
