On my Daytona, the furthest is probably 5 hours at one time. On my Bonnie, I have done 8 hours of back-roads multiple days in a row. Never did I feel like I was maxxed out though. I do lots of trips around the Great Lakes on my Bonnie and have been scouting good twisties on motorcycleroads.us. My plan is to hit some of the best around me and camp or utilize couchsurfing.org while I do it. I have a cross-country trip planned for this summer with some buddies on our Bonnies and I have 4 3-5 day trips planned on my Daytona thus far. Between these planned trips and my track days I should have a banner year if I can stay rubber side down.
