On my old Ninja 250 I had a Ventura Rack and did overload the bag when we did our trip to QLD last year. Even then I needed a bigger bag, the Rally Pro Ventura bag (51 liters) just didn't have enough room. Plus the rack only holds 9kg which really isn't much. Now am getting the Ninja 650, what other options are there for sports bikes, am after a soft bag option not a top box or panniers? An older thread had someone asking about a horse shoe style bag, any reviews on this? Or is this likely to stuff up the paint by just sitting on the back of the bike?
