alvaro84 when I look at your BMW F650CS the area I see that might help areo and not harm looks is saddle bags close behind the legs and not much wider than the legs but quit long, about 12cm wide 60cm long and 40cm tall. They would have to be on some form of rail so that they could be moved back to accomidate a pasanger. I don't know if you can find something like that in the EU but if you can they would help. For some reason BMW's have always been very good on fuel economy, and of all the manufacturers they have made the effort from time to time at providing areo bikes to the market. unfortunatly the market is driven more by fashion and style than good areodynamics
