I am in the process of correcting the model year on my California titled Japanese Domestic Model(JDM) CB750K1. I need to list the production month and year for it. Since JDM bikes do not have the right side plate, I need your help.

The VIN# is CB7501120XXX. My US model K1 is CB7501093XXX with a production date of 05/71. Please check your VIN# against mine and let me know what production date you have for your K1.

Thank you

I am thinking 10/71 or 11/71, the last of the K1s. Hopefully, there are more people on this board with K1s who can chime in. Thanks

I see. I guess I will call it 09/71 and get it corrected and titled as such. Thanks

What does title say ?
Most K1 are titled 1971.

The title says 1972 because the PO brought it into the US in 1972. Even the insurance company (Geico) says there is a discrepancy with the model year and needed manual confirmation of model year.

 Even bikes sold in the U.S. were sometimes titled as the next model year, I've often mentioned my leftover k2 cb500 was re-titled as a 1973. Later, Honda lost a class action lawsuit in New York and repaid me $37.  Later, I realized it had the small gauges and the rest of the 73's I saw had the big ones. 
  Apparently that's how I got a 1970 sandcast sold at Christmas in 69, it the first 750 sold at our local shop and the second one was a 1969 diecast.  The guy that assembled them still owns the 69 and remembered who bought mine new. I'd prefer my title to say 69 also but the buyer was probably asking for a 70 and got it.

The JDM bikes did their own thing number wise; 750 K1 frames started at 1055209 and engines at 1057052.
Link http://forums.sohc4.net/index.php/topic,136534.msg1538826.html#msg1538826. Member Dream750 is/was the expert on the JDM bikes but I haven't seen him online for a long time. For your purposes 9/71 is probably as close as you will get. I have frame 10558xx making it quite an early K1  8)
71 or thereabouts 750 K1 - this one should have been put down

I have a JDM K1 but its in Canada, eh so all I had to do was get an 'out of province' inspection to get it registered, as we dont have the Title system. The VIN is 89,XXX.....
There are lots of little differences between the same year North American bikes and the JDM bikes.
