Which CB550F do I have?
« on: February 11, 2018, 05:47:03 PM »
Hi everyone  I've recently joined the club after acquiring a 1977 CB550F.
Can anyone tell me please how do I tell if it's an F1 F2 or an F3 model?  Frame No: CB550F-2113617  Engine No: CB550E-1153376
Any help would be very much appreciated.

Best I can do, is to direct you to the CB550F Parts Lists. In the first few pages of every parts list you'll find the frame- and enginenumbers listed. http://www.honda4fun.com/materiale-documentazione-tecnica/parts-list/parts-list-cb550 You need the right parts list to further determine the 'area code'.
BTW, there never was a CB550 F3. There was a CB550F, CB550F1 and a CB550F2. Yours is a F2. If it's original, it doesn't have the harmonica rubbers (front legs) and probably will have the wiring outside the handlebars. In case you don't have the Owner's Manual, they're here: http://www.honda4fun.com/pdf_libretti/550/550_77/libretto550_77_1.pdf

Thanks guys I'm pretty sure it's a F2 now.
Deltarider it doesn't have the harmonica rubbers on the front legs. I'm not sure what you mean when you say it will probably have the wiring outside the handle bars? Do you mean electrical wiring or brake/clutch cables?
Sorry if I sound dumb.

Electrical wiring is probably outside.

Hi Gary and welcome to the forum.

Some bikes run the electrical wiring from the light switches, horn push button, starter push button, cut off switch and indicator switch etc, through the inside of the handlebars. It will be easy to see if your wiring is tied outside of the bar or run inside the bars.

Welcome to the mad world of the SOHC, wiring inside or outside will not ID your bike if someone else has changed the handle bars to non originals. It is the VIN (frame) number that ID's the Bike and it is clear in your case CB550F 2*****  ;)

Just jumped in the car and went to the lock up to check the bike.
There are no rubbers on the front forks and the electrical wires run inside the handle bars is it still a F2?
I also noticed that the front flashers/indicators are bolted to the side of the headlamp. Nearly all pictures I've seen have the flashers/indicators about 6" down attached to the forks is this normal?

A CB 550 F2 original head light bracket looks like this. If the indicators are mounted to the head light, maybe someone could not get a original head light bracket or stems. These old girls are getting on a bit and have been changed with non original parts over the years  ;)

Thanks for that Trigger.
I'm going to try and source some original headlight brackets as I would like to keep my bike as standard as possible.

Welcome Gary from another 550F owner.
The US site http://www.sohc4.net/cb550-model-guide/    is pretty confusing, even for US owners as it lists an F1, F2 and F3 and then if you scroll down shows pics of a F0, F1 and F2. Don't think the F0 was out in the UK. In reality our F1 looks similar to the F1 picture shown and our F2 similar to the F2. Take it yours is original UK bike.
The correct headlight ears in good condition are pretty rare. There are two varieties around, some have brazed on fittings that only fit the large US indicators. (US K type) You need ones which will take the screw on stems. And of course the tapered screw on stems are also rare as they are for European small indicators only.
My import is a 76 F1 (made in 6/75) but has a VIN CB550F-200*****. More confusing.

Hi Seabeowner, mine too is an import from the USA. I'm getting very confused about frame/engine numbers I'm pretty sure that my bike is an F2, I think??
