Other manufacturers might but Yamaha have always been as already stated, adaptors for the 10mm thread can be bought to alter thread direction to use universal mirrors so unless adaptors are fitted it is as follows.
[color=rgb(51, 51, 51)]Reverse thread & tightens going anti-clockwise for the right hand side, and a right hand thread (standard thread & tightens going clockwise) for the left hand side.[/color]
[color=rgb(51, 51, 51)]So to answer the OP, lefty loosey/anticlockwise. [/color]
