Mine goes flat in about 3 weeks. It does however have a tracker. Not sure whether it has done it from new because it was ridden almost daily. Now I don’t ride so much I walked into the garage one day, pressed the button, idiot lights but no TFT, battery was almost completely flat. Now it’s kept on a trickle charger when not riding. Bike is just under 2.5 years old so will probably fit a new battery next winter.
