Givi site says V35 will hold a full face helmet. Twisted Throttle site says XL full face won't fit. Will someone with Givi V35 cases let me know if full face helmet fits. I know that each helmet has slightly different shape and the V35 shape is different, but what do owners say. We use HJC full face (L & M) and it would be a bummer if we can't stash helmets.
