Cheers Doc, The SW Motech's on your GT are mounted at three points and would (I think) be a lot stronger than my Ibex bars, which are only mounted on two points (but have a connection through the front).
They are however solid feeling and now that you mention it (roll over's), would let the Gt lay flattish in an oops moment. I only thought I needed them now that I'm a weakened heart surgery survivor...... wouldn't want to damage my pride and joy (or my shattered ego) in a parking lot oops or a u-turn on gravel etc...... so these look like they will be good enough to cover me until I'm fully cooked and back above 95% recovery (prob in 2019).....
I always wondered how many GSA riders might have watched their bike roll over and over down a hill with those massive oem bars.
Now there's a thought....... maybe your SW M's will make it easier to pick the GT up should you ever suffer the embarrassment of letting it lie down for a rest.........

I hadn't thought of that...... I'll still need help to lift mine if I ever drop it.......
Regards from the other side
