Distinguishable by their dual exhaust outlets and low-slung pair of expansion chambers, early CZ motocross bikes became known as "Twin Ports." The two exhaust ports were a carryover from the 1950s, used to combat cylinder distortion caused by heat in CZ's hard-working two-stroke singles. Following Joel Robert's title-winning 1964 season, CZ made production bikes available to club racers that were very close in specification to the works machines, including magnesium brake hubs and on some bikes even mag engine cases. "In the annals of motocross, the CZ Twin Port stands out as an early exotic racebike," said Ultimate Motorcycling magazine in its CZ retrospective. "The 250, as well as the 360, elevated the sport to new heights with a hint of how new exotic metals could transform machinery."

Difficult to find today, some experts reckon that as few as 50 1965 CZ 250s made it to U.S. shores. Now 50 years old, this 250 Twin Port is a true survivor. The fiberglass gas tank and seat are original to the bike; even the side numberplates are original and intact. The stock Jikov carburetor has gone missing over the years but the rare aluminum airbox is included in the sale. A longtime resident of the Mork collection, this largely complete, aluminum-case 250 Twin Port is sold as a restoration project.
