Why flash a Kove ECU?
Kove makes some of the most capable rally and adventure bikes in their class, and riders push them hard. Their factory maps are written for emission tests and a wide range of markets, so they run lean at part throttle and keep the response soft. A reflash lets you set fuelling and response for your exhaust, your altitude and the terrain you ride.
