The target of this research is highlight the application of Lean Manufacturing tools in motorcycle assembly process. Productivity increase, line stoppage control and 5S methodology are expected to be improved. Specifically, the entire production flow was mapped and Lean tools were chosen to be implemented in the shop floor. Also, key performance indicators were used as the way to show and share all improvements and benefits reached. Lean manufacturing is a production system focused to identify and maximize the added value of the products based on wastes reduction including value stream map, standardization and 5S.The project was developed starting from the literature research and case study. Direct observation in the shop floor collecting all data and analysis of them made part of this study. Regarding data, were collected the cycle time of all process, material flow and 5S status of the area. Significant achievements were reached during and in the end of this project. It was increased 15% of 5S score. Line stoppage was reduced by 52% with important actions like standardization and homologation of new method of material control. Significant increase of 37.5% in productivity and capacity raised the company to the next level. As indirect result is worth to mention a reduction of R$9,900/year in extra shipments due to material control improvement.
