Front wheel covers became a feature for the first time, with the main aim of the piece to, in theory, increase top speed. ✊ They do this by smoothing the air flow around the front wheel, concentrating the air and reducing turbulence created by the front wheel. All of this creates an aerodynamically more efficient motorcycle, allowing it to cut through the air easier and reach higher top speeds. 💨 Ducati have been the manufacturer to take this concept the furthest, having both front and rear wheel covers, but Aprilia's design seen here, is possibly the largest front wheel cover design we have seen. Cleverly, they also use the cover as a brake caliper duct too, directing air to it, keeping temperatures down and maintaining optimal perfomance! 💪」3月17日 18時12分
