Had a stash tube from J&P Cycles on my RK. Mounted to the backside of the lic. plate under the luggage rack ... worked pissa!

 

yea I put mine in my wallet but you can either can the Reg tubes they make for that purpose or you can just get a tool bag and a water tight bag ...

 

I keep my papers in my fork bag, or I will forget them eventually. I dont worry about if my bike stolen, since all thats on my registration is my address...which any kid with a computer and internet can get by typing in my name. I used to keep a copy of my registration with my bike, until a cop told me I had to keep the original copy on me or the bike. And sure enough it says that on the back of the registration.
