I have a 1972 R75/5 and a 2000 R1100RS. I ride each bike often (usually at least once a week if not more frequently) and have never placed them on a trickle charger. I had occasion to place the Airhead on a trickle charger for a few days and when I started her up I noticed the battery seemed stronger than usual.

Would the R1100RS benefit from being placed on a trickle charger too? I know the Oilhead has a stronger charging system so perhaps it is not all that beneficial.
