Abstract--Design on firefighter motorcycle by using an automatic scooter motorcycle is one of many efforts to reduce losses caused by fire disaster in a densely populated area, especially if the fire occurs in a narrow road that cannot be passed by firetruck. However, initial research for firefighter motorcycle requires some improvements so that the performance of firefighter in using this particular tool can be optimized. In this research, the improvement of firefighter motorcycle performance can be implemented by improving the engine of automatic scooter motorcycle, improving bracket as the holder of centrifugal pump, choosing centrifugal pump and choosing the way of installing centrifugal pump to automatic scooter engine. As a result of the improvement, the performance on water spray on firefighter motorcycle for extinguishing fire is increased, the way of maintenance of the utilized parts is easier and weight addition from the centrifugal pump does not affect the engine performance of the utilized automatic scooter.
