View Full Version : New guy, new project

Hello all, new member here from the 'naki.
My daily ride is a '98 1200 sporty, but I just picked up a new project, and have a few questions.
It is a Honda CB125T, but I'm unsure of the year. I believe it is 78-80. It has dual carbs, spoked wheels and a 6V battery. The S/N on the neck is CB125T-2027174
Also, it is de-reg'd. The bike is very complete, so it should be an "easy" restoration, however is it much of a problem to register a bike of this vintage? All the parts will remain stock, I don't plan on any mods.
Any model specific info for this type of bike would be much appreciated, I don't know much (anything) about this model of bike, other than its going to be a fun project.
The pic is not of the actual bike, but it looks exactly like this.

Cheers

Thanks for the info.
Does anyone know where I might be able to find a front end for this bike? I don't know how I missed this when I looked it over but it appears as though one of the forks is bent. Any common bikes that might interchange like an XR100 or similar? Cable operated front brake.
Cheers

Can be straightened on a press by the right guy if not creased. More likely is the chrome being rooted.
Also check the front brake action. I've rebuilt one of these by replacing the thrust bearings as they were collapsed. Pads out and look with a torch. It was an unpleasant job and I wouldn't recommend it for the faint hearted but crucial for braking.
So back story of why this bike? Had one as a lad? Always wanted one? Or it just showed up.
Reason 3 is least likely to get finished.
Often date codes on wheels and hydraulic lines that help trace age, though the last one won't help in this case.

Backstory.....got a lead that there was an "old honda" at the auto junkyard near where I work. Since I always have a project of some sort (my sporty being the latest) I thought I'd check it out. The wrecker went to a farmer to pick up a car and the farmer told him to get rid of the bike too. It was parked inside so its in pretty good nick. Far as I can tell it hasn't been registered since '81. Everything is intact, motor kicks over and has compression, no evidence of oil leaks, gearbox is smooth, both brakes work and the tyres look brand new. Shows 47k on the clock. Carbs and throttle cables are seized.
Stripped it to the frame last night and didn't find any surprises.

Many similar (Honda) bikes of that size and era ... shared the same parts.
This is a parts guide to determine the year your model was built ...
1973 - First year the bike was released in the US as CB125S0.
1974 - Front drum brake changed to disk, tachometer was added.
1976 - Engine displacement increased from 122 to 124 cc (7.4 to 7.6 cu in), tachometer was eliminated.
1979 - Front disk brake was changed back to drum.
1980 - Point ignition was changed to capacitive discharge.
1983 - The bike was not produced this year.
1984 - The electrical system was changed from 6 to 12 volts.
1985 - The last year the bike was released in the US, headlight shape was changed from round to rectangular.

Looks like good fun, I shall look out for you as you sail past me. Will be just as quick as anything else at the moment through the joys of Waiwhakaiho. Best of luck with the rebuild and most of all, enjoy it :yes:

I'm guessing the waiwhakaio valley is one of the few places where this bike will blow by everyone! What a nightmare. If you see a bare metal sportster flying down the center line into town around 5pm, honk and wave, but don't open your door!

Cool project.
The tyres will be rooted - don't ride on them.

Fresh out of the barn where I think it has been sitting for a very long time. Not bad for $200.

Indeed. Just like my mate Pete's old one.
Make a plan, small bites.

Brings back some memories. My first bike was a silver version, but it had steel mags rather than spokes. It could keep up with traffic on the motorway - just!
Didn't have it that long though as I moved up to the requisite two stroke.

Well, took it down to the frame, powder coated everything steel including the wheels, lots of elbow grease, rebuilt the carbs, rebuilt the brakes, converted her to 12v and took it for the first ride tonight.
Starts first kick, purrs like a kitten and pulls through all the gears, no hesitation or flat spots, unbelievable. Pretty happy considering it was rescued from sure death from a scrap metal dealer.
Now to start the re-registration process. I've talked to the guy at vtnz and it actually sounds rather painless.
Pics to come!

Paint has been left original to preserve a bit of history, still need to get seat recovered. WOF inspection Monday.
The wheels were powdercoated whole, didn't cost much but I'm interested to see how they hold up.

You didn't fuck about.
The exhaust wrap will for sure ad value....or cover up rusty headers.
Should be a dam good commuter/hack around bike that will last for years and cost fuck all to run and keep running.

Ha! The exhaust wrap is covering a patch job, you were close. I might get some new pipes in the future, but the shipping is killer from the UK.
