Luggage is a problem if you travel for a long time. You need to bring so many things. These tank-side bags create instantly 18 liters of extra space and they keep your legs out of the wind (and rain). It's a set from Hein Gericke called 'Tuareg' (desert warrior) and they survived three years of terror. I still use them. The only downside: They turn into wings at 140 KM/h.
