DC2R like everyone else has said is more raw and u can feel every bump. cabin noise is pretty lound if u dnt have a cd player and your on the highway all u can hear is the engine reving. not that its a bad thing.
DC5R is smoother an looks nicer. even though i drive a DC2R i like the DC5R.
power wise stock for stock there is only like 10 kwts difference.
the DC5R is def softer to ride and a better cruiser than the DC2R
