Does anyone have the BMW soft bag 2? My Marsee tank bag broke late last season and I'm thinking of getting the soft bag replace it. I have always had a tank bag to carry small day to day things (cell, water, maps, liners, snacks, ect.) I do a lot of off road riding on my GS and wonder how well the tail pack will hold up. thats how the tank bag got broke. With just two straps holding it on, I wonder will it be secure enough? Also, how durable is it?
