Scott, the Triumph boards are 11.25" by 5" in size.
Aside from that, the angle seems to be correct for our riding position.
The mounting system seems more secure also.
The Rivco's, which I have not used, have a single mounting point. They fit into the clevis where the footpeg goes.
The Triumph has a double mount hinge plate.
This would keep it from loosening and twisting front to back.
