I have used this luggage system on a couple of bike and cannot fault it. It is extremely well made and and very versatile. The system consists of a pair of 'L brackets' which are permanently attached to the bike onto which different racks are bolted to take the various bags. I've got three different bag sizes which I use on different occasions. The main advantage of this Ventura system is how it doesn't increase the width of the bike thus allowing easy filtering through traffic and how it sits heavy loads inboard on the pillion seat to maintain good balance of the bike. Day to day I keep the sports rack on the bike and use the smallest bag for day trips. For long weekends away I attach the taller 'pack rack' and use the largest bag and for long trips I zip the large bag and a medium bag back to back and this gives me approximately 70 litres of capacity. The bags a waterproof and also come with a storm cover to make extra sure.
