Topic: 1971 cb750 build month?

[captain rats]

My 1971 bike has no plate on the head tube. It's an Australian delivered bike and apparently it is not unusual for them not to have one. Anyway just wondered if anyone could deduct the month of the build?

Frame number is cb750 109246X
Engine number is cb750e 107342X

Thanks ( the x is replacing one number)

Closest I can find is that your bike was sold between 70 and 71 with a release date of 9/21/70.

I'm not sure if to-the-month information is available or not.

Thanks mate,

Thought that maybe someone who had one at a similar number might have meant I could estimate the month.

Cheers
