Don't quote me on this, but I was told that starting this year or next all bikes sold in the U.S. have to have their ECU accessible via OBDII port. Prior to this Triumph was one of the few, if not the only, brand to have the OBDII standard, the other brands all had their unique plug.
I've read that KTM is getting around this by building an adaptor that plugs an OBDII port into their standard plug, so I'm not sure what, if anything, the end consumer gains in that scenario.
