Now, fair enough, it's good that the bolts bend, it absorbs impacts instead of transferrng them, but it's a matter of balance and from what I saw of mine, it's not quite right- the bung never hid an object, it bent that way just from sliding on smooth tarmac.

Also, the parts are expensive... Bend a bolt (and you will) and it's £10, new bungs are £20 IIRC. I mangled one side when I got knocked off, and scraped the other by cunningly falling off at some traffic lights (I have a note from my doctor saying that wasn't my fault!) Whole new set of Motosliders was less than the replacement costs for 2 bungs and a bolt. And the Motosliders really have been tested, by the notoriously crash-happy members of SV Rider.

Not to totally slag the R&Gs of course- it's an extremely clever design, and they work with lowers better than any other. But I think that bolt will prove to be a weakness, or at least a point of contention.
