I drive my KLR everywhere, including 2-4 hour (one way) trips every weekend. I am tired of strapping a briefcase to my bike when I go on those trips, and would also like a space to carry day to day items. I am in college, and college kids like to mess things up and steal whatever they can, so I need a tail bag that has locking capabilities and is able to be very firmly attached to the bike so it will deter most common thiefs. Waterproof would be a huge plus, but it's not necessary. This KLR is my first bike, so I know very very little about the technical terms and slang for bike parts and companies. So, can you reccomend a tail bag for me? Thanks in advance for the help!
