I've been struggling with this since I bought my new LS2 Valiant Avant Helmet, which I love. I couldn't decide between full or half face and this helmet is the perfect solution. BUT, since the face flips all the way to the back of the helmet, there is no room to attach my Sena bluetooth. The lip of the helmet by my ear is extremely wide so the standard clamp-style mount does not fit. Also, the slide for moving the sunscreen visor up and down is exactly where the mount would go if it would fit. They make a specific bluetooth for this helmet, but it is a poor one. They also make the Sena 10R Low Profile version which uses a hook & loop mount and would be perfect, but that one only has a range of a half mile and allows you to intercom with 4 riders. My solution so far has been hot gluing the whole Sena clamp mount to the outside of my helmet which works for a few weeks at a time. Has anybody found a better solution? Please help!!!
