Tourmaster saddlebags

[White Dog_imp]

The Tourmaster Select bags (and maybe other models) are attached to each other via large velcro straps which lay over the passenger seat, so you can position them wherever you like. You might be able to mount these straps underneath the seat. My shocks hold my bags out of the rear wheel. Mine are mounted such that the tops of the bags fit underneath the rear turn signals. Even that low, They cover the hand holds. I've never had a passenger on the back of my cycle (dang it). As a suggestion, maybe a tank bag or backpacks would be the better solution if you are only planning to use them a couple times a year.
