HONDA CB400F 1975-79, 408cc OHC four, 37hp, 100mph, 60mpg, 375lbs Neat but gutless four that can be problematic after 20k pistons, camchains and primary chain. F2 model lasts better (50 60k). Quick seize disc and rain causes the engine to cut out (look for newish, sealed coils, HT leads and caps; electronic ignition helps). Cushdrive wear ruins chains and gearchange (linkage also wears). Check oil sump bolt as it's too small so can break or round off.
HONDA CB1/CB400 S/FOUR 1992 on, 399cc w/c DOHC four, 53hp 125mph 50mpg 385lb Rather bland styling but nearly as much poke as the replica 400's (on which the engine's based) and much more comfort for general riding keeps it in the game. Earlier CB-1 looks better, goes very nicely and handles well but quite a few were crashed in the UK can withstand high speed slides with only minor apparent damage.
