The Jawa 250 motorcycle, produced between 1934 and 1946, was the first task of the newly established Restoration Workshop at the Faculty of Mechanical Engineering, VSB-TU Ostrava. This motorcycle has a very simple design. Since 1930, an excellent motorcycle racer and designer Mr George William Patchett was involved in its development. A total of 14,000 pieces of Jawa 250 were produced by 1946.

The very first glance at the motorcycle before the repairs started, showed that its technical condition was very unsatisfactory, both for road traffic and for further preservation of this vehicle. Following the original state and recommendations of the Charter of Turin, it was decided that this motorcycle will not be only renovated but restored. This meant preserving its original features and patina, of course, with the maximum use of available original parts,  and maintaining its safety and reliability as a means of transport.

The condition set for its operability was the reason for a single departure from the requirements of the Charter of Turin, as it was decided to restore the motorcycle to reach the same condition as when it had left the factory, i.e. provide a partial change of this motorcycle due to the removal of all partial modifications done by previous owners. This was particularly true of later modifications done to the front headlight, carburettor, side boxes and tandem saddle (carrier).
