Maybe most of you guys will disagree with me on this one, but I would say look into the Rincon 680. Honda is known much better then anything else for reliability and there transmission is second to none. Gonna be down on power from the v-twins but the price is where you want it. Ride quality is there and it will handle 2 people and the speed you want to maintain with no issues what so ever. just my .02 cents
