Hello, i'm new at this forum, and also a possible new owner of a honda cb500.
I rencently saw a 1977 honda cb500 k four 1977. I contacted with the vendor and showed me the specs card of the bike.
The problem is that while the frame/chassis of the bike is a cb500K the engine number is a cb550e.
Does any one know a place where i can find all the honda cb500 models? i look at some sites but cant find a cb500 with frame number "cb500k" and also i cant find any cb500 with a cb550 engine.
On Hondas like my 1974 CB 750 K4 and your 500 the engine has an E in the serial number. The "E" denotes an engine serial number for parts purposes. Even my 72 CT 70 has an "E" in the serial. The frame is "CT70-200...." the engine is "CT70E-20...." So the fact that you have an E on the engine number is normal.
