The old CB500 four taken out to the point where it became rather fragile and vibratory without instilling some blood and guts into the design. Has some uses as a tourer or hack. Beware of rattly top ends, caliper rot, burnt out starters, trashed oil filter bolt head and blown gaskets. Unless suspension upgraded age turns handling weird. Neat looking Nighthawk model, in both OHC and DOHC forms. Prices for stock CB650.
