I use my DR650 , i have a PVC rod holder mounded on the left side of the bike behind me. It will hold a 5"6' inch bass rod broke down into 2 pieces. I have even taken it flounder gigging. Polarbear soft cooler strapped across the rack with my LED adventures gigging light and a 3.5 foot aluminum gig. Gets topheavy when you have a good night.
Here is the DR patiently waiting for me to get off work to throw some finger mullet at flounder. "you can see my rod holder in the pic"
