I bought the HB bars for my 1150GS for the sme reason. Seemed pretty well designed and cheaper than the OEM, as well as better protection that the SWmotechs (IIRR).
My GS got mashed by a myopic Fiesta driver and got totalled. Bars did the trick though: cylinder heads were fine: pitty the impact ripped off the centrestand and sump....
However, do think about the expense. You can get plastic cycinder ends for abrasion: other than that the boxer pots are pretty robust. Any impact that messed them up would have killed the bike!!
If you decide to get them, go for it they are nice kit!
Adventure: it's an experience, not a style!
(so ride what you like, but ride it somewhere new!)
