Little to no Tech Motorcycle suggestion

Was thinking about an older KLR 650 or even a vulcan. Im looking for something that is not flashy at all and has little to no "tech". I want something that I can easily work on but is still reliable along with not having to worry about it getting stolen as much as other bikes. Maybe even be able to drill a surfboard rack into it too.

- Any suggestions on what to look for on marketplace?
