Restoration

 

 

These notes are intended to pass on things we have found out as restorations have been completed. This will include in depth investigations into how HONDA did things back in the late 50s and early 60's. We have discovered that nothing is set in stone when it comes to how the early Japanese motorcycle market behaved and what we in the west think of as logical doesn't always follow for the Japanese. I have been helped by many owners some of whom have had vast experience in restoring all nationalities of motorcycle but by far the most help has come from Mr Kozo Kadomoto san in Japan. He is my Friend and Mentor for all things HONDA. I thank him

Nothing can be taken for granted when restoring a CB92, just because it looks like it's never been touched that counts for nothing, nearly Fifty years have gone by and our forefathers loved to mess about with bikes just like we do, so unless there is an unbroken line, backed up by documentation tracing your bike back to the shop who supplied it then your bike is undoubtedly not as it left HONDA. I have lost count of the number of emails I have had from owners who bought the bike in 1969 and it was original untouched with pink side panels etc, desperately trying to disprove my information. This website is the result of over 30 years experience with dozens of people having an input, most notably from Japan. If you have any information then let me know as it will help future owners. This website is there for all those interested in CB92's, or Bensuper as it is known in Japan.

BADGES - the original badges were Gold, I have done lots of experiments and now believe the silver ones are gold ones that have been in the Sun. This started because I had a bike on show in a dealer and couldn't understand why one badge was silver and one gold even though they were both gold when fitted, when the bike was turned around amazingly it had two silver badges. This has since been confirmed by considerable research in Japan, using contemporary colour photographs.

PAINT - Four Colours are available, Red, Black, Dark Blue, and Light Blue. and that's it. Parts painted include Frame, forks, headlamp shroud, rear tail light, and centre stand although we have seen stands painted black on late '64 bikes. A lot of spare parts from Honda came in black, and most I have seen are in the dark blue. Early bikes, '59-'60 had alloy parts (Tank, Side panels,  which were painted silver. Top shock covers and handlebar clamps were polished and lacquered like the later style of hubs on '70s bikes. Early front mudguard was finished in the same anodised way as the levers etc Although later fenders were painted, White front edge was for Japanese market where it denoted a 125.) See fender section

SEATS - Black, Red, Blue and Yellow seats are known.

RACE SEATS - Normally black suede type material but some red ones are known in the US.

RUBBER PARTS - White, Very Light Blue and Grey/Blue front mud-flaps are known. Black, Grey/Blue, and a Very Light blue rear mud-flaps are known. White, Very Light Blue, White and Grey/Blue caps are known for the pump. Tank knee grips are Black, although we have seen three version of the knee grip. An early glue on with ears, the one supplied for most years with ears and the latest after production version with no ears.

CABLES - Very early bikes '59 and maybe into 1960 had very thin Grey/Silver cables with alloy grease nipples. Later bikes have the thicker Grey/Silver cables with steel plated grease nipples.

HORNS - See horn section

CB92 CYLINDER HEADS - There has been much talk about Cylinder heads, but let me make it clear, in over 25 years we have never seen CB92 heads without the cast in , cast iron skull for the combustion chamber. The C92 touring model however is all Alloy, and many C92 heads have been modified to take a Tacho Drive so be aware of what you are buying. Pics to follow
