Thanks for the pictures, guys, and sorry to thread jack. I have the tail light support on my bike, but it's coming off soon for an upcoming race (Desert 100!). I see how you both have it mounted, and that makes great sense. I will likely do the same if you both agree that it's strong enough back there with those little 5mm bolts. Better than using the airbox holes/handles, I bet.
Not sure what size the bolts are exactly but their website shows that they supply M6 and M8 bolts. Either way they are plenty strong enough for lifting the rear of the bike.
