Due to its potential but it small intake it was decided to try to improve the RD500 engine by machine it to take the reeds, carburettors and cylinders of the RGV 250 / RS250 engines.
The first engines had the water inlet manifold based on each cylinder which interfered with a smooth air / fuel intake trajectory. The “mark II” engines that we designed has a water inlet manifold through the upper crankcase as with the RGV 125 which improves carburetion significantly.
After the Engine was designed, build and distributed to several race fanatics, it was decided that a complete bike must be a possibility too. This project is still in progress.

Our contribution in this project:
– Conceptual design in 3D.
– 3D technical designs.
– CNC parts development.
– Build and testing.
