More is better. I've been using a 1.25 AMP charger/maintainer successfully for my MC's for many years I would opt for no less amperage to cover all uses of my MC as often they are long rides charging and sometimes short rides that require recovery with not a lot of time for the alternator to charge it up so the battery must be potent enough and have sufficient recovery capability. More qualified than I can talk to that, but Scott is on the right track as the chargers must cover all types of situations for all types of MC batteries. Kaladin can certainly explain it far more eloquently than I am sure.
