"According to federal standards, the engine on/off switch must be on the right handlebar, and the high/low beam light switch must be on the left. These locations, however, are reversed on the following models:
2008-2009 Matrix 50 2008-2009 Matrix RX 150 1999-2003 PN2 2004-2009 PN2B/Beamer 50 2004-2006 PN2C 2006-2008 PN2F/Beamer RX 150 < 2007 PN2G" That's how mine and my brother's are... we bought a pair of almost new '07 Beamer R4's (Mod PN2F) around the holidays.
I was curious about the odd switch locations but didn't know it was a violation of federal DOT standards.
Maybe I'll give them a call about it... suppose they'd have to swap out both switch clusters for new ones.
