I searched but didn't find an answer here or when I googled around. Not even in the giant "Official Nighthawk Thread." Ignore age and condition for the moment.. And think in terms of a commuter bike with some weekend use when not riding the DRZ. Is there any reason an 84-86 700 Nighthawk S might be a better bike than the 91 and newer 750 Nighthawks? Or were the newer bikes an improvement over the older bikes? I know the 84-86 is about 50 cc lower in displacement, and has a shaft drive. But other than that I don't see a whole lot of difference. Feel free to define better any way you like.
