I have seen at least 3 different pictures of 2 full size helmets in there, so it's obviously
doable, but question is will ANY 2 fit, there's all sorts of shapes and sizes, and some have
differently shaped additions that might get in the way. Either way, I'd put a big topbox on
it just to be sure that everything and anything can fit.
Can't answer your glovebox question though.. too early to tell probably if it's flimsy or
built properly.. but some people manage to break everything.
The DT looks built like a Mercedes to me.
