Key specifications
Overview
The 1976 CZ 250 MotoCross Type 980.5 stands as a revered icon in the world of cross-motocross motorcycles. Manufactured by the Czech company CZ, this machine was designed to dominate the competitive motocross scene of its time. With its rugged styling and robust build, the 980.5 garnered a dedicated following among riders who appreciated both its performance and reliability. As a 250cc two-stroke single, it perfectly blended lightweight agility with the power needed for thrilling off-road adventures, catering to seasoned racers and weekend warriors alike. At the heart of the CZ 250 MotoCross is a potent 246.20 ccm single-cylinder engine that churns out an impressive 34 horsepower at 6800 RPM. This allows riders to experience a responsive throttle and exhilarating acceleration, making it a joy to navigate through the most challenging terrains. The engine's 11.5:1 compression ratio and finely tuned JIKOV carburetor ensure that the power delivery is both fierce and controllable, allowing for confident handling on jumps and sharp turns. The 5-speed gearbox, paired with a chain final drive, provides seamless gear transitions, empowering riders to exploit the engine's full potential on the track. The CZ 250 MotoCross boasts a tubular frame that offers both strength and lightweight maneuverability, weighing in at just 99.5 kg (219.4 lbs). The front telescopic oil shock suspension with 200 mm of travel absorbs bumps and impacts, while the hydropneumatic rear suspension with 90 mm of travel enhances the bike's stability and comfort on rugged trails. With drum brakes on both ends, riders can expect reliable stopping power, although enthusiasts may find the need for more modern disc brakes. The bike is designed with an 8-liter fuel capacity, ensuring that the adrenaline can keep flowing without frequent stops. **
