The Rih is a small-series racebike concept from Maximilian Näther of the German design agency Zoom. It’s aimed at ‘hobby racers’, but there’s some interesting thinking going on here. The intake system starts with ‘lung-like’ membranes on the fuel tank, which flex according to how much air is being ingested by the Aprilia V4 motor. And the logos on the tires are baked-on ‘thermochrome’ pigments, which change color according to heat: the rider can then see when the tires have reached the optimum operating temperature. ‘Rih’ is an Arabic word for ‘wind’, and the next step for Zoom is to secure sponsors and build a working prototype.
