I noted today as I had left my bike untouched and not plugged in for 2 wks when I came to start as I turned the ign on and the fuel primed things sounded slow, dab of the magic button confirmed and it clicked struggling to start.
So it's not had a battery since I've had it and looks original and always optimised so I'll treat it too a new battery.
Best deal for battery online ! (gen1)
Thx Dave
