Yep, late 09 onwards to some time in 12 I think, had factory dual batteries. When they had the floods in thailand and went back to japan they went to 1 battery again for a while, then back to 2 when from thailand again... mine is a 10 and has the 2. They are connected in parallel, but it is easy as to put either a solenoid isolator or dc-dc charger in to charge the second one. There is a lovely spot on the driver's side quarter panel to fit a redarc or similar solenoid type isloator.
