Hello everyone need some help identifying year of this Honda cb125. I no its a twin cylinder single carby. The chassis number is CB125-4024951 Any help would be appreciated thanks.
 
The frame number seems to indicate a K3, which is important for identifying compatible parts. Here is a link to CMSNL for that model. The K3 seems to have been released around 1970.

I don't know about Australia, but the year here in the US can vary depending on when the title was issued.

Im thinking around that year just very hard to actually confirm. The spedo is in MPH Not sure if this indicates origin. And its 6 volt battery from what i researched 69-73 were only 6 volt may be wrong.
 
CMSNL.com is one of the largest sites for new Honda parts for old models like yours. They classify your bike as a CB125AK3, just to complicate it! They also have the Honda parts catalog for your bike online. This will help you if you wish to look elsewhere for parts, as you can compare prices with the Honda part number as a reference. Good luck.CB125AK3.jpg

The "year" is immaterial. The bikes were produced in series and then sold over time. You know you have a K3 Frame, double check that the engine serial number is in the same series - particularly important with the 125's as there are a number of versions that can bolt in and who knows what's happened over the last 6 decades there.

Dang. Those are close enough that could actually be the factory engine. They were produced separately then crated and shipped to dealers so they’d never exactly match.

Nice little scoot scoot machine around town, may be able to crack 70 kph with a tailwind but it’ll get 2.3L/100km single carb makes maintenance much simpler as well.
 
DCTWA, what are your plans for the bike? Recommissioning (getting it running and riding) or a full resto? Either way, you could do worse than join the local Vintage Japanese Motorcycle Club vjmc.org.au You might be able to get good help from members in your state. Cheers

Full resto is my plans i think it is worth doing besides one side cover tail light lense and indicator lens its all there. its been sitting in farm shed since 1980 was running when parked. Gentleman i brought from brought of original owner in 1978 rode for two years and put in shed. I would presume I'm 3rd owner.

That's great. I've never seen a CB125AK3 in the flesh. The shape of the tank is, I think, quite different to other Hondas of the day, and the side covers are unusually large, yet the two tone, up and down, paint scheme visually unites the tank and side covers. Cheers
 
Nice bike (Dmoh) DCTWA, congratulations. Good luck and have fun with restoration.
