I'm preparing to make a rack for my DRZ400S and can't decide if I want to mount it to the seat bolts like so many do (Tonns, Rugged Rider, Suzuki, etc) or like B & B Offroad as can be seen here: http://bboffroad.com.au/shop/online-products/carry-racks/carry-rack-suzuki-drz400.html Seems it would be sturdier and have more weight capacity if mounted to the seat bolts. However, for me, it would be easier to make a rack that mounted like the B & B Offroad rack. I plan to carry 1.2 gallons of gas back there in a heavyish steel gas can many miles over wash boardy gravel and dirt roads. I'd hate to break my sub-frame. Any thoughts?
