I've got one of the generic AGM batteries from Staab Battery, it was in the R65, up until January, when the Odyssey battery in the oilhead started turning the engine over noticeably slower .
In this desert heat, I get at best 4 good years out of an Odyssey battery, it's only got a 2 year warranty in a motorcycle, and with a current cost of around $130 for an Odyssey battery, I thought I'd give this Staab battery a try .
Don't know what kind of service life to expect from it yet, but time will tell .
