I'm the second owner, '07 RSV. Bike came from a dealer with a battery connection for a battery tender. Small polarizied two wire lead connected to pos. and neg. terminals on the battery, sticks out from under the seat.
Riding for 45+ years, have never used a tender. I always removed the battery for winter storage, used a 2 amp charger a couple times over the winter months.
For what/where should I look for a battery tender? Seems it would be much easier than removing/reinstalling the battery. I've seen a couple on the internet, but they have the alligator clips, not the small plug-in type connector.
