An opportunity has presented itself to get a new bike... I need to choose between the 800GS and GSA.... Not one for the big aluminum panniers or top boxes nor do I need the larger fuel capacity. I am thinking the regular GS would be a better choice for me. I have a 2005 F650GS now with the Vario Cases and they have enough capacity for our trips which are 90% road. I have a tank bag for quick access items and a tail bag for extra capacity if need be. Other than the larger fuel capacity what is the main advantage of the GSA over the GS?
