Iam having trouble with the ABS on the 2000 1150 GS i have recently abtained. I have read that the battery causes the failure most of the time. The previous owner said the battery is about 5 years old,it starts good but i've been keeping it on a charger but from what i understand it can start fine but still cauce ABS failure. So what battery is best to replace it with to help with this problem. and i know this may not fix the ABS but the battery is 5 years old and needs replaced anyway. Thanks.
