What is the make and number of original battery fitted to 989r in the UK
My Battery is not and my OCD is telling me to fit an original.
Also is the lead under the passenger seat to connect something like a
Charger or Optimate3?
Don't worry about the original battery supplied by MV Agusta.
Any lead acid brick will do as good as the original.
Once You buy a charger there will be cables with it to connect the charger to the battery via a plug.
So You could attach the cables to the battery once You connect the battery to the bike.
