Identifying a Honda C70

A few days ago, I received a request for the identification of a Honda C70 and this is the outcome:

20170710 170747


Your statement about this motorcycle is as follows: You declare that the frame number is C70-803xxxx and the engine number is similar except for the C70 part. You have a round headlight, 6 volts and no electric starter.


Your statement of the engine operating on 6 Volts: This means that your engine has contact breaker point and therefore your engine originates from somewhere between 1972-1981. From 1982 on, the operating voltage was 12 volts and the ignition was done by CDI. [1]

Your saddle is a two-tone saddle which belongs to a C70C and C70E models. [2]

The specific attachment of the passengers leather handle grip indicated that this belongs to a 1982 or 1983 C70 Passport. [3]

The problem here is that your frame number does not match with this model, nor does the fact that you have ignition breaker points and not CDI as the Passport has.

Your frame number has a match for a Honda C70C. This model has been produced between frame number C70-8022434 and C70-8039828 [4]

“The C70-C models are easily distinguished by their two-tone dual seats and restyled headlamp cowling and leg shields.” Restyled does not mean square, but since there is only round or square, I cannot give a clear statement on that.

Warnings: You declare that the frame number and engine number are identical (in number). This is basically impossible. Until this day, I have not ever seen a matching number and the production of frames and engines happened separately. They can be close though, but matching is something I find hard to believe.

Time to (carefully) gut the 1966 Honda CD125

I am getting quite fed up with the fact that I can't ride this beauty because of its crappy electrics. I burned a few bulbs, which were pricey and the time has come that things get repaired. With the best luck, it will be still next summer when this bike can be ridden, but it's worth making a new loom for it and replacing the ignition cables. One of them is broken anyway. "It will be ready to ride when you pick it up!" Yeah, no.

Look, I guess this is still the original wire loom? So much manual work as you can see in the next picture.

70.000 mile mark for the Honda VF700 Sabre

Giving it an oil change now. The rear distribution chain is a bit rattly and the whole bike looks a bit crappy, but it's still alive. Even with the occasional carburettor hickups haha.
Anyway, I have been looking at a future replacement and it might be a bike from the new brand Mash. Lovely retro, but new technology. Or maybe again a Honda, depends on the budget.
But for now, the VF needs to keep doing its job and for that, it gets the best oil available.
