There were 307cc (58 x 58) big bore conversion kits back in the late 1970's for the CZ 250 and some turn up from time to time. From what I've been told they were a Motokov GB made item. Basically the kit was CZ 250 cylinders bored out to 58mm. to take the 350 pistons. I bought a 1978 CZ 250 with a 307cc kit fitted back in the 1990's which was nice to ride with the extra engine torque. I still have the kit and plan to fit it to a 1974 Type 471-0 I'm restoring.

Brought one brand new 247pounds I believe great machine dynamo used to come loose stop Points working clutch and throttle cables used engine oil instead of two stroke front brake to small

Ta kanapa to jest zmodyfikowana oryginalna kanapa od tego modelu. Podstawa kanapy ma przyspawany metalowy, profilowany ręcznie zadupek obleczony w szyty na wymiar pokrowiec. No i oczywiście jest cieńsza gąbka :)
