I have American Machine bar backs from Pirate
They move the bars up, back, and make the grip angle more horizontal. No problems with brake or clutch lines etc.
I have an RS, am 5' 10" with 32" inseam.
I switch back and forth from "touring" to "sport" configuration depending on the ride.
If I am going to be predominantly touring I install the bar backs, an Aeroflow touring windscreen and a peg lowering kit.
The windscreen and bar back combo is especially useful since the tall windscreen reduces the air flow over my torso. Without the bar backs, the tall windscreen increased the load on my wrists.
There is some interference between the Aeroflow windscreen and the handlebars at full lock with this set up but it is tolerable and not unsafe. With the RS stock windscreen there is no interference.
I have gone on several of the typical rides where you ride the highway for some distance to get to a good set of twisties, then ride the twisties and then return home. I carry a hex wrench along and when I get to the twisty roads I stop and remove the bar backs, then reinstall them when it is time to ride home. Takes less than 10 minutes to do the swap.
I don't do this on short, (one day), trips but on longer trips I find it worthwhile.
My "sport" set up is essentially the stock RS without the peg lowering kit or the bar backs and the standard RS windscreen.
I like this much better for sport riding and also when riding in the heat of a Texas summer.
Is there a way that you can order from US and pay essentially half of the Australian price plus shipping? Also, you can often find used ones here in this forum for even less.
If you need a middle person to get and ship some to you let me know.
