Hi,

I rewrote to the owner : "Hi, I am interested in the story of the CB 750. You wrote in your ad :"Based on the VIN it was built in Japan in late September 1968 before being exported to the US."
But referring to : https://www.motorcyclistonline.com/blogs/making-honda-cb750-king-motorcycles#page-4

"Two american Honda employees Bob Young and Bob Jameson spent more than a month in Japan in 1969, assisting with final development of the CB750 Four." So I don't think Honda started a mass production of the CB 750 in 1968 but perhaps do you have pieces of information about that.

Otherwise could you please precise the engine number."


Does someone know this museum where this CB is parked in Maryland ?

Hi,

As you can see on the ad (https://www.ebay.com/itm/1969-Honda-CB/222793535549?hash=item33df87903d:g:PvkAAOSwuShaWP9D&vxp=mtr)
the #31 is for sale and I asked for the engine number.

Does the VIN plate on the early sandcast indicates the building date ? In this case September of 1968.

Furthermore i can see some details on the pictures :

- the emblem on the left side-cover is not the good one, it's a right one.
- the air box comes from a K1 or a K2, the original models were smooth and available in color to match side covers.
- referring to the fender, earliest models must have at least one sharp non-rolled edge,
- mirrors should have chrome acorn capnuts at top of stem,
- the lower right exhaust muffler is not a HM300 model.

22 000 $ seems to me over priced.

Hi,

I think that the question is more difficult to answer than a yes or no.

The Theseus's paradox can perhaps gives a good approach : https://en.wikipedia.org/wiki/Ship_of_Theseus



 

Hi,

Here is a link about the book "Honda Motorcycles" by Aaron P Frank.

He says that the first "Project 300" was the N600 engine (a 598 cc twin SOHC) adapted in a motorcycle frame and Bob Hansen seems to have been the man who convinced Mr Honda to build a four-cylinder engine.

What do you think about these pieces of information ?

Hi,

The K2 presented in the article is not a... K2. Probably a K5 painted and made up as, more or less, a K2 :

- fork,
- gear change pattern,
- right-hand fuel tap,
- side panel badge,
- tank...

So...

Hi,

Thanks for the piece of information.

I wrote 2 years ago to Honda Japan and Honda US, unfortunately they answer me that Honda did not save the production data of the period 68/78.

So Bonhams seems to be right and the machine is one among 36 UK CB.

I save the data.

Thks 

Thanks a lot.

I confirm the engine disassembled shows cambered pistons and specific camshafts.

Hi,

You'll see in the ad below that there is no engine number... As the owner says : We believe that the engine case had been replaced a long time ago with a new one with no number".
