New to me.....Old CZ 400

I picked this up a couple of months ago. 75 400 Falta. It has had lot's of mods done to it. It runs.......real good. It was built for and raced in the modified class at the CZ World Championships in the 80's.



I'm going slow with it fixing the stuff that didn't work.....like the gas tank. It served as the fork stop. And yes those are real Simons forks. A 78 Honda CR 250 tank will work out fine. The Works Performance shocks were way to stiff on the bike so I built a set of Curnutts for it. I will be going through this bike totally over the next few months. I know pretty much who did the mod's but can't seem to find out any info on who rode it. Anyone on here know?

Nice bike....luv the 'ol CZ's. I got my eye on older bro's '74 125 CZ. It's in peices

125 HOW RARE IS THAT?

Not that rare...looks just like the 400 above but the fins on the head are vertical running front to back. (not radial) Same seat with the side flaps, same coffin tank but my Bro has the stock tank with the rubber knee pads in a box still brand new. That funky pencil / school bus yellow. Has a down pipe as well. This isn't it, but it's what it is: ......Last pic is with stock tank (ugly)

The yellow tank (taxi cab) CZ 125's are very hard to come by in useable condition. The other two pics you posted are 125 Falta's. They are very rare in the US. If your brothers bike has the yellow tank stock, it is not a 1974. Give me the motor and frame number and I can tell you what it is. A lot of the parts are interchangeable. I have a good friend that has a 125 that will smoke Elsinores.

that tank is criminal .imho
the cz tank wont mind the forks hitting it . might even damage the forks haha
good friend of our has a 400 falta aswell . goes awesome .

and remember if your knee doesnt hit your chin it wont hook the next gear haha

Yeah I knew I wasn't sure the year...I thought it was between 72-74. I'll figure the numbers out if I ever get my hands on it. It's my brothers project bike now. The pics had zero research, I just pulled them off a quick search on google. Thanks for clearing things up.

The stock alloy tank is near perfect. I have a stock frame that will go on.......maybe. The Honda tank works fine for what it is intended for.

The Tank looks like it fits well.

sweet project!...i know next to nothing about cz bikes other than pictures but i have several brno/cz rifles and pistols and they are always well made, accurate, and just great performers.

I am thinking about purchasing a CZ pistola here soon.

very good value, there are better quality out there but you will spend alot to make that jump. i like their stuff. their 75 and its variants is a legend.

My good friend who owns Bar-Sto precision machine (gun barrels) thinks very highly of him so that is the way I'm going.

Those re-furbished ones above look really good but are ~lacking without that radial head design ... What do those bike feel like when riding them?

I found out it is not a Bill's pipe. It is a Magnum.

I rode the bike for the first time on Sunday. My first time on a CZ in 15+ years. This thing is stupidly fast with the porting work that has been done and the pipe. A little much for an old guy like me.

I'm not sure Ray Ray, I never rode one....but want too of course.

ray ray,

CZ's are a very neutral feeling bike. They turn very well and go in a straight line pretty good. But like all 4" travel bikes they hop around if the shocks aren't right. Stock they have real broad power bands. They can be breathed on and made fast. The hardest part with them is the 3" shifter throw, it feels like you will hit your knee into your chin. They are heavy but you can lighten them.

It's been awhile but I have been busy on the CZ. I went a totally different direction from my first thoughts.

As of yesterday. I have gone through the whole bike with almost all new parts. The Husky tank works the best out of all the others I tried.
