The goals of this RaD project is a new inovative Czech engine in a new Czech motorcycle, road and racing version, so we hope by this to restore the tradition of competitiveness of Czech production motorcycles. Expected specifications: ENGINE: Four-stroke, single cylinder water cooled, with innovative turned head, with DOHC, 2 overhead camshafts driven by a chain, pressure lubrication. The engine equipped with our own optimalised fuel injection to improve performance and reduce emissions. The suction valves made of titanium. MOTORCYCLE: Next innovative properties: pressure lubrication of camshafts and tappets, separate lubrication of engine and gearbox. The combined frame welded from high strength steel tubes and duralumin. The rear wheel and rear swing, the fork on shock absorbing central unit. The front wheel hydraulic telescopic fork, disc brakes, multi-disc clutch in oil bath, hydraulically operated. Five-speed gearbox with sequential shifting. Electric starter. Furthermore, the project will achieve: - Homologation for road use - Participation in official races - Manual and spare parts - Increasing of the prestige and production capacities of the Czech companies involved in the project - Reduction of the emissions, increase of performance, thus a progress in the technology, which will be applied in the manufacturing of a complete motorcycle. The motorcycle will be ready for serial production according to the schedule of this project.
