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.

- Limited Suspension Travel: Though adequate for the time, the rear suspension travel of 90 mm may not meet the expectations of riders accustomed to contemporary motocross standards.
- Kick Start Only: The absence of an electric starter might deter some riders who prefer the convenience of modern starting technology.
In summary, the 1976 CZ 250 MotoCross Type 980.5 remains a classic testament to the rugged charm and performance of vintage motocross machines, appealing to those who value both history and the thrill of the ride.
