Just in the process of listing a set of Marzocchi AG Strada shocks I found in my loft. I seem to recall I bought them off a fella who'd just had them reconditioned (the person who did the recon put me onto him) he had a CB750 IIRC. I've just measured the eye to eye length and it's approx 326mm, top fitting is a eyed one, bottom is the usual claw fitting typical of Hondas in the 70s.

Can anyone let me know what they should fit? I can't remember offhand what the eye to eye length is for the 500 I bought them for, my bike is right at the back of my garage and under a stack of stuff so it's not readily accessible.

sure I'd replied to this last night......   :-X
I've two sets .

First set, OEM .. distance between centres of mounting holes = 320mm

Second set, aftermarket ... distance between centres of mounting holes = 315mm

Dealers generally uote them as 13 inches or 325mm .. but dont specify between where and where.

For a definitive you could try Steve at http://www.bike-revival.co.uk/exp.html. He's easy enough to yak to on the phone

Measurement is generally taken from centre of bolt hole to centre  of other bolt hole.

So it looks like the Marzocchis would be ok on a 500/550 at least, 5mm is nothing.

From aged memory the 750 originals were about 1 inch longer than the 500 but Girling replacements were all the same
