"Thanks alot. Pretty useless."
I know, but that is just how it is. Front end geometry is critical to handling, and so the differences between bikes do mater. Then added to that, front end racks can carry weight all over the place. I built a rack a few years back that moved the bags a little to the rear of the normal position of centered over the axles. That made for great handling, but every rack is different, and will behave differently on bikes with different HT angle and trail.
The good news is that if you have standard 72-73 degree geometry up front, you will be riding geometry the racks are designed around, and you will likely find it easy to work out something for your bike.
