Just thought this would be a cool new topic. If there is already one in existence please let me know so I can delete this one, or a mod can do it. As for me I finished my under tail project and rode the crap out of it.
someone say leverage?If you aren't using a rack that's cantilevered like the Givi unit, then your assessment is pretty well spot on.
Leverage is a b!tch.
Like this? Extending up and under the subframe?If you aren't using a rack that's cantilevered like the Givi unit, then your assessment is pretty well spot on.

My thoughts on why it failed: That rack vibrates (it's not exactly light weight.) It's been there for over 30k miles (probably closer to 40k), and has been used on a freeway that undulates sharply on a daily basis for 2 years solid - about 15 miles of harsh pavement each way. I think that this, over time, work-hardened the aluminum until it finally failed.
Re: Cantilevered? Yes. But I'm thinking of just not running with the rack for now... Other thoughts I've had would be to run bracing forward to the front rear seat brace, but that would require welding, and time, neither of which I have access to...Is the rack like cantilevered off the back? If so, would this not put a twisting moment into the subframe brace that was designed for a straight down pillion load. More and different bracing sounds like it would be beneficial here. Maybe start a thread with pics and the collective brain-trust of SVR might come to the rescue!![]()
Btw, yes, this is cantilevered. It supports a load on one end by pushing down on the fulcrum (grab handle) and lifting on the other end (passenger peg).Like this? Extending up and under the subframe?
