Not sure if this has been discussed altready on here. Anyway a bit of a mystery bike.

Just looks like a standard F2 with earlier engine, not sure what he means by the left front disk, and it being prototype , but given the early frame number who knows, look at all the historic cross over models in the cb range, there is loads of transition bikes , mystery indeed

Hes talking crap, its a standard UK model F2 with earlier engine

It was the the VIN plate I saw that made it interesting Bryan but of course it could have been swapped from another frame. Honda font stamping look pretty authentic.
Having never owned an F2 was it designatet G in some countries?

Yes Ash, all F2 are G designated as I understand it. So it's a low production number F2 but nothing to say it's not normal run production machine.
As the others say, just seems to be F2 with it's original engine missing.

When i tried to get an import F2 registered years ago i was told it was only UK F2 that had the G

Yes, I'm not certain Bryan but was looking at one that the owner said was brought in from South Africa that had a G Id. Anecdotal though, so not sure of accuracy.

Just looked at the VIN plate on my F2 and it is G, 1000266

The one i was doing came from US but the person dating it said G never was on US bikes so it must have been exported there then re imported, i just took his word for it.
F2 was a nice bike except for those valve guides and no matter what Honda said it had to be a known problem as Fowlers had a lot of sets in stock
-
Kibblewhite in the USA sell a set of valves and guides via CycleX that fixes the problem. Much harder guides and longer for better valve support.
-
Three friends had them from new, all had to have guides replaced. One still has his original, think the guides were smoking at roughly 19,000 miles, and head rebuilt by Honda dealer.
You can see and smell the engine oil when following them as they start to wear.
As you say Bryan, seems to be known about by Honda even before they went out to dealers. Possibly why they have less oil drain returns from head in the first place.
Suppose they had to send it as last iteration and stop gap as they knew the twin cam was advanced toward production then to replace it.
-
The replacement genuine guides for the F2 are much harder than the originals but the same part number, they are referred to as Delta parts. Bloody dishonest if you ask me, just so Honda don't have to admit a mistake. The real problem is they cocked up the geometry to fit larger valves and the rockers push the valves sideways causing wear.
-
I've always thought they are a good looking bike though, especially in blue.
Not that we "raced" on the road officer, ahem, but they are pretty quick from standing start. My friends one would beat most things then for approximately 1/4 mile, he weighed only 60 kgs and could just launch it faster than most. It'd take a Z1 to beat it over that distance.
Think Honda where caught short with no other bike to develop mid 70s as they'd pushed r&d into goldwing etc. Then saw Suzuki GS coming and panicked a bit.

I had one in the early 80's.
Looking at the Tax disc it was in 81 when friend and me, on his CB 550, toured in Germany.

Its back on
