(S4R is not side mounted, first thing I looked at!) Oh yes they are
My friend's two week old S4R battery peed itself...
Anyway, real problem. Affects ALL ST frame based Monsters. That's all monsters 2002+ (plus 2001 S4). To be clear, that means all newer Monsters, 620 and up.
Any questions, I'm on the link posted above by Eamonn.
