The Praga ZS 800

Praga ZS 800

TGR Staff - 02/08/2023

Created by the same expert engineering team behind the acclaimed Praga Bohema hypercar, the new Praga ZS 800 combines a suite of advanced motor racing production processes and materials with the character and design details of its 1928 BD 500 ancestor.

Sporting a chrome molybdenum steel frame, titanium exhaust system, as well as unique woven carbon wheels, the ZS 800 weighs just 313lbs dry and with its air-cooled, 773cc four-stroke parallel twin engine, delivering 50 horsepower. Titanium is used throughout the design, with almost every screw, axle, nut & bolt of the chassis and engine made from the lightweight, high-strength metal. The exhaust system is also fully titanium and weighs just 4.8kg as a result – with select elements constructed using state-of-the-art 3D printing.

Premium materials such as duralumin alloys, noble chrome molybdenum steel, and forged carbon are also incorporated into the ZS 800’s design. Dedicated to achieving the perfect structure, the engineering team utilizes the very latest production processes to manipulate complex materials, including over 300 hours of five-axis machining.

The ZS 800’s Chief Designer, Jan Žuži, said: “Strong and extremely lightweight materials – such as carbon, titanium, chrome-molybdenum steel, and aviation duralumin – enabled us to reimagine the rigid rear wheel suspension, the front swingarm fork, and the hydraulic drum brakes. “These futuristic materials and Praga sports division’s latest production facilities have enabled us to transfer those elegant historical design elements to the present day, and to build a motorcycle with contemporary driving characteristics and a unique feel.”

Praga will produce just 28 of the ZS 800, which are now available to order with deliveries starting mid-2023, and the first of these heading to a client in Dubai. As expected these limited edition bikes are priced like rare art, with each selling for just over $91,000.
