Fork length ?

[Grewth]

Could any kind CB550 owner please tell me the length of the assembled forks, ( fully extended ) please ?
I measure from the centre of the front axle to the top face of the tube.
Q. Are all the 550 forks the same length  ?
Or do they vary between the F and K models etc ?

Measured my F1 and they are 72cm.
I know that the the F1 forks have different stanchions from the K I used to have, but the difference could well have been in the damping arrangement.

Many thanks for that !
In desperation I actually tried measuring a photograph of a pair of CB550 forks with a tape measure across the screen of my phone.
Then basing my calculations on the sliders being 352mm long I got an overall length of between 716mm to 727mm based on two different photos.
When you get the chance,  could you possibly manage to check your fork slider length.
The sliders on my CB750F1 measure 352mm from the axle centre line to the top face hidden under the dust seal.
I'm hoping that the 550 sliders are the same length.

500 are a slightly different length but will fit

I have a sneaky feeling the CB550F2 (which also shares the same part number as the K3) has longer sliders than the F1.

I have some F2 lying around, I'll measure them tomorrow. If I get a chance to go in the loft I'll measure the stanchions as well.

Hi Grewth

I have a K3 which currently I have got one stanchion apart to sort out the brake adjustment screw thread, I can measure the following if it helps you.

Centre of the front axle to the top face of the tube & the internal parts spring length slider length etc

Ken did point out to me there are on the inside of the stanchion by the flat section there should be 3 cast numbers which tells you which stanchion you have fitted I have it written down some where I see if I can find it, The important part is that the slider should be 35mm diameter .

Hi Grewth

The top set of measurements is from a set of CB550 K3 which I have as a spare set both fork tubes sets are 35mm as per Honda CB550 and have a casting number of 341 which I believe is for a K3

The 2nd set of measurements marked Original set is the set that came with the bike which the lower leg casting is bigger unfortunately the casting number has almost been polished away

Hopefully the picture will upload this time fingers crossed

If you want to make me a offer for the rear shocks Don please email me
