I am currently fitting rebuilt wheels to my '75 400/4 that I restored in 1986 !I couldn't find NOS DID rims in '86 so I used Suzuki Takasago rims (bought from Queens Park Motors Oddjobb ) and non-standard un-butted spokes. Anyway, with eBay and internet, (not around in the mid '80s ! ) I have just rebuilt replacement wheels with the proper period DID non-side-scripted rims and the correct Honda spokes.I noticed that my Aug 1975 bike had a hex headed rear wheel spindle fitted and it's not correct as it should be the -286- part ..like the CB250K , although I believe it was BZP finish on the CB400F, not chromed. Also I noticed that among my collection of front wheel spindles, some have hollowed ends and some are solid. I think the '75 should have the solid end, BZP finished version. Any ideas? I think my original rear spindle must have been from a late F2 model or perhaps a CJ250T.
Every 550 F1/F2 i have owned has had the hex head rear wheel spindle. The shaft is too thick for a 400/4. Not sure about if the late 750's shared the same shaft mate.
