Also it is pre-activated in Can-bus mode (which is mode 2 of the charger). So no extra adapter must be bought, no extra socket must be wired to the bikes electronics, and so on.


So all you need to do is: plug the adapters cable in the motorcycles socket, activate the charger and forget about it...

Optimate will take care of your bikes battery totally automatically and keeps it in good shape.


The Optimate 4 has 2 charging modes installed which can be changed easily.
