I'm looking for a set of lockable hard saddlebags capable of stowing a full face helmet. I just bought a 2012 DL650 and had a DL1000 a few bikes ago with the Givi monokey bags which I liked. The OEM bags are $750 USD which I assume includes mounting hardware. Twisted Throttle has brackets for the 2012, but Givi has a bunch of models now - kinds confusing. Of course I want something that minimizes width, but still fits a helmet. Recommendations?
