I picked up this bike about 2 months ago and have been cleaning it up to get it in good running shape. Not trying to make it a show piece but more of a rider/racer. I like my bikes to be clean and period correct as much as possible.
I thought I would share a few pics. Also I could use any info out there on where to find a 23” front tire.
This is what the bike looked like after purchase, with new fenders I installed. Then I decided to go bit further.

Looks like you are doing a good job and great bike. I had a 23" whole wheel and hub a couple of years ago but chucked it out- stupid as now hard to find!
Good luck with the bike and post more pics- loved these at the time with the red rocket engines!

As far as i know there are no mx style 23" front tires left on the planet which is one big reason why people don't buy these bikes. Most people that have them put 21" front wheels on them. Also, the 1980 is far better in nearly every regard and is legal for calvmx GP1 and ahrma GP classes.

The tank is beautiful! I hope you leave it as is.

I have a whole 23" front with the stock Bridgestone still on it. Would LOVE to see it go to a good home. It has the Trail Wing dual purpose on it and a quick search looks like that's the only one left out there for the 23. Hope I'm wrong in your case.

Basically out of my garage is good enough. whistling

Oh ... and the tire is in pretty good shape hardly worn.

I used a scotch brite wheel on an electric drill. I don’t know what grit it was, Brown in color. I put the leg in a vise and went around the leg. I didn’t want a high polish just trying to get something that resembled the original finish. I was happy how they turned out.

Yea, I kind of was assuming that about the 23” wheel/tire. I didn’t check that before I purchased. Probably wouldn’t have held me back but would have been nice to know first.
I was figuring I would need to get a 21” wheel. I heard they handle different with a 21” wheel. Is this true? If so how big a difference?

Thanks. Yes, actually feel the same way and plan to leave it as is. I want to ride this bike and don’t want to make so perfect I would afraid to do so.

unfortunately the 21" wheel changes the steering head angle and helps one issue by improving cornering but it causes others, and there is no way around it, but unless you ride half way fast, it will be "ok".

Get a hold of Newman. He knows all about using a 21" front wheel on the 79 and the Al Baker Mode that is required to make it work.

Yeah, I have no clue !!!

laughing Reading through this thread thinking, "the Al Baker mod is easy" and then I see your post. I think I have the article on my computer at work.

What is the Al Baker mob?

Cut about 9 mm out of the top frame tube, pull it back and tack weld in place. Heat the front downtube where it joins the cradle to stress relieve. Gusset the lower cradle and weld and gusset the upper tube. Gets you where you want to be for the 21 inch front wheel.

The 80 model seat contours up into the tank much better than the 79 after the frame mod. A little taller at the front of the seat if you stick with 12 inches of travel. 10.5 here, front and rear. Works Performance pro racer adjustable piggy backs and Race Tech modded Fox Forx with emulators and full spring/no air. Young son is a little shorter than I am.

Thanks for the tip. This is not exactly what I was hoping for. Longer travel forks won't do the trick? I am short as well, the 79 seat may be just fine for me. If I was able to find a 23" tire, does the bike work fine like that or is it still suggested to install a 21"? I plan to ride the bike, possibly race it but really not trying to make it the bike to win races with. Just a fun thing.
Your bikes look good.

My first 79 CR125 I had back in 1994 had a 21 inch front wheel on it with everything else being stock. It didn't handle too odd as I remember. It just had the crappy stock suspension on it.

have a copy on a thumb drive of how Al Baker from FMF would cut the frame just in front of the air box remove 8mm then weld bake together, I am going to do this to mine as I am planning to race it, not a big deal if you have a strong flat table and can weld.

Haven’t made much progress lately. I have decided to stick with 23” front wheel for now. Mainly because I just want to get the bike rideable at this point. Thanks for the info on the frame mods. I am likely to do the frame mod later.
Does anyone out there have a stock silencer that would part with?. I have seen a few on eBay, but they look pretty beat. I have a super trap that has been modified to fit. Who ever did it did a nice job, I just don’t want the super trap. If someone is interested in it I would sell it or trade.
I have attached a few photos of the bike as it sits currently and the super trap.
Thanks Photo

Doing a great job...I would keep it close to original & not cut up the frame....seems like a lot of work for minimal gains...

Well that bike looks good and the tire too. Now, how do I get my hands one?
Do you have a silencer you would sell?
