It feels good to ride again after a couple of weeks, and a ride in the wet and cold was really fun. I love this thing more than is probably justified, but I do. It will be a while before I scratch my motorcycle itch. Plus it has cool details, and I can slap obnoxious stickers all over it.
The brown one is the master key that can program the spares. If you buy a Vespa, make sure you get the brown key.
