The right side DHM is as good protection as a promise to pull out... Absolute cack. You're spot on about the link in the middle, the thread's too short (It might be 60mm long, but the supplied bolt only goes about 10mm into the thread) and it's just ordinary aluminium. It's not even capable of bearing the tightening torque without suffering, let alone protecting the bike in the event of a crash. The left hand one is pretty solid, though.

Motrax did tell me that the bolt would be replaced with a longer one when they refunded mine- I was lucky enough to have it fail on fitting instead of in the line of duty- but I really don't think it has. Really it needs a longer bolt, and a steel spacer. In fact, really it needs to not bolt up in that position at all, but to go through the engine like all the good mushrooms do.

If I was buying new ones tomorrow, I'd buy GSG Moko (cheap on Ebay...) or JHS. My old R&Gs served very well, I couldn't find fault with them at all, but people whose opinions I trust totally found them too weak- and it seemed to be as much machining as design flaws too. I sold mine planning to fit a set of lowers, and after 2 big crashes and one smaller one, they were still in great condition (I'd replaced the rubbers, mind)

I replaced those with the new R&Gs, which are very good. The bolts that retain teh bungs bend quite easily but don't snap- this means the bungs themselves will be good for only one big crash, but on the other hand bending like that will absob a huge amount of energy in a crash. The replacement parts are very expensive though- more for 2 rubbers and a bolt than an entire set of Ebay GSG Mokos would be!
