Vintage CZ Motorcycles

CZ MotorcyclesCZ is short for Česká Zbrojovka, which is a Czechoslovakian firearms manufacturer that is also known for making CZ motorcycles. In September 1919, CZ was established as a branch of the Škoda Works Armament in Strakonice, Czechoslovakia.

CZ began making street motorcycles in 1932, but abandoned racing them in 1972 so that they could focus on creating CZ motocross bikes. They became very well known for their powerful two-stroke mx bikes and was the first company to use expansion chambers in their exhaust pipes.

Although CZ was very successful in Grand Prix motorcycle racing, they were even more successful with motocross racing, winning seven World Championships and dominating the International Six Day Trials Competition.

Despite CZ’s racing success, the company lost a lot of the motorcycle market with the increase of popularity in the less expensive Japanese motorcycles in the 1970s. In 1993, Italian motorcycle manufacturer Cagiva purchased the motorcycle branch of CZ, with intent to create new proprietary bikes, as well as new CZ models. Cagiva failed in 1997 because of financial difficulties, therefore bringing an end to CZ Motorcycles.

  • Tom Stockstill says:

    Tom Deluxe here. (was in So-Cal vintage bis 90 to 05) now Montana, and just completed a CZ477 rider for personal use at 750 ugh! Seems quite satisfactory as such.???
    However at about 40 mi. into road testing this little thing, (made from 700 mi donor), it spit out the primary chain through a big hole (made by same) in the front of both cases. No foreign pieces appear and the sprocket are both damaged. Am presently considering it a one of a kind incident or perhaps advise if other known incidents. Thanx “Tom”

    • mike says:

      Yup my old 72/380 20/1 formula is 128oz. divided by 20oz. = 6.4oz. per gallon. Castrol golden spectro if they still make it.

  • Dan Barnes says:

    Pal plugs. 3.2 before top dead center. Always ran 20 to 1 Castrol, probably would run 50 to 1 now. Klotz was good but Amsoil is the way to go. Happy landings! #31 Danny Barnes

  • Rich Jeffery says:

    I am looking for information on what the suspension is on the 1991 CZ Model 514. The up-pipe 400 motocrosser. Specifically, was the FRONT suspension manufactured by CZ or another supplier. Also, whoever supplied it, was it worth a darn?

    Many thanks and BRAP ON!


    • Mark Celino says:

      Type 516/513/514 models had CZ’s own forks they were terrible as stock, but I put some Ceriani springs (from a WMX125 Cagiva in mine and some light oil and no air pressure) and they were great from then on. The rear shocks are completely rebuildable and tunable and need 145 psi (air or nitrogen). Different spring rates available from Increasing the diameter of the exhaust stinger also livens up the motor…

  • Ray says:

    Premix. I bought one new in 74.

  • Steve says:

    All CZ motocross bikes were pre-mix only. I had good luck with a 32:1 mixture. I haven’t had a CZ in a while, but I used to run Klotz synthetic oil with a mixture of Klotz Nitro fuel additive. I don’t even know if they make the Klotz anymore. CZ’s run best with a Mikuni carb & a reed valve. I don’t remember which year they started using reeds, but CZ’s are hard on spark plugs if they have the old points & condenser ignition. Mine were 71 & 73 250’s. Safety wire & locktite everything you can, they vibrate almost as bad as an old Maico. The way they make power, they are like a light switch, either all on or all off. The only way you can tear up one of their trannys is to crash real hard on the shifter side & drive it into the cases. I used to race one in the 70’s & we would have clutch hand on top of the helmet starts. When the surgical tube was dropped for the start I would have the engine revved up & just stomp it in gear then grab for the left side of the handle bar as the front end is coming up. Nobody could beat me to the first turn. Miss my old CZ’s, had a lot of memories riding on them.

  • Paul Mcginley says:

    I have just bought an incomplete 1974 CZ motocross. Could someone tell me if there should be a 2 stroke oil tank or is the oil and fuel pre mixed before putting into the fuel tank?

    Many Thanks.

    • Anonymous says:

      One quart Klotz 2 stroke per five gallons gasoline, premixed.
