Looks like an CX100, last of the round jugs (best looking motor of the bunch in my ever so humble opinion
).
The small block fans (V7 family) say it's more fun to ride a slow bike fast than a fast bike slow. The big Griso really drives this home. I think the CB is a very good compromise between the V7 and the Griso. If MG had a nice 850 bike (that they imported to the States) I may not have gotten a CB. Their V twin really seduces you. But the CB has its' charms too.
Truth be told there are an awfully lot of really good bikes out there and it is wonderful we have the selection to choose from. Just about every itch can be scratched.
