Originating 1928

The ZS 800 is an evolution of one of the most successful, classic Czechoslovak machines, the 1928 Praga BD 500. Today, a unique combination of advanced engineering technology and classic design details have formed a one-of-a-kind machine bringing an iconic heritage into the modern world.

Our state-of-the-art technology enables us to create a production motorcycle featuring unique wheels and integrated hydraulic drum brake. Forged carbon wheels with carbon tensioned spokes, together with our fully hydraulic drum brake system, make the motorcycle even more astonishing.

The sculpted girder front fork is the jewel in the crown of the ZS 800 and an exercise in master craftsmanship, utilising 5-axis machining with everything made from the finest 25CrMo steel. Incorporating a fully adjustable Öhlins suspension unit, with titanium spring, it all works in harmony to produce an eye-catching front, and deliver a poised and a riding experience to stir the soul.

Art of

A combination of elegant engineering and creativity has ensured our team surmounted any production challenge they faced. One such innovation is the 11.5L fuel tank that forms a structural part of the frame, saving a huge amount of weight. Unwilling to compromise the aesthetic, the tank has been embellished with a forged carbon cover to preserve the beauty of the bike.

Titanium exhaust fixture


Exceptional quality materials such as duralumin alloys, the finest chromoly steel, forged carbon and titanium feature throughout the design. Titanium takes centre stage, with screws, axle, nut and bolt of the chassis and engine are made from the material. Not to mention the fully titanium exhaust system containing multiple 3D-printed titanium elements. For the majority of the motorcycle is manufactured by 5-axis machining, requiring more than 300 hours of production machine time per bike.

Dry weight of just 142 KG


Advanced and intricate engineering developed through our motorsport experience, understanding of premium materials and incredible attention to detail result in an unbelievable dry weight of only 142 Kg, complete with 50:50 distribution between the wheels.

Heart of the King

Praga ZS 800 features the engine from the cult Kawasaki W800. The design of the motorcycle is engineered to perfectly complement this iconic engine in tribute to its beautiful architecture, bevel gear cam drive, historical legacy and last, but not least, its incredible light weight and fuel efficiency credentials.
