This may be a strange request, but I've just purchased a 1984 BMW R65LS Motorcycle so that's taken up my time for the last few weeks. What I want to do is take Photo Gear with me in the Panniers. The Pelican type case would seem to be way to go & I've noticed these Adorama's & others on the net reviewed http://www.photographyreview.com/pls_3123crx.aspx
But maybe someones got some specific success with MotorCycles. (Pictures will be forthcoming of this gorgeous machine)
