plate holder - I'm amazed KTM doesn't have a decent plate holder! This is just dumb. I was sold a stamped steel Ducati item, but it didn't fit either. Redrilling the reflector bracket was an option; I just wanted something more elegant.
I just took a piece of aluminum stock from ACE hardware (1/8" x 1" x width of plate) and drilled four holes in it. After rounding the edges, I countersunk the center holes for flat head CS machine screws and spray painted it flat black. Its very solid and stealthy, looking just like its a factory part. I inserted rubber electronic cabinet feet/bumpers into the lower holes. Total cost about a buck.
This space for rent.
