Looks like a pattern forming here? I'm thinking some clever re-design of the sub frame/tail rack may be in order?
I hope you guys can come up with something good ... that will hold up off road with luggage.
I can't imagine what would happen if a LD traveler was using a typical Top Box or good sized Tail pack. Travelers tend to "overload" ...even though most top boxes post a limit of something like 11 kgs. max load.
Most exceed that ... plus add on a GL or panniers to that.
Wonder how the Terra sub frame/tail will hold after a 1000 miles of washboard with 24 lbs. +/- mounted on the tail?
