<p>The windscreen is convex shaped to offer least wind resistance and is designed to concentrate and deflect air, dust and rain drops away from the riders face without the need to build the screen as high as the riders head. The screen is provided with trough like indent (3) in the centre region of the rear upper edge as seen in the direction of travel. The rear edge of the trough converges towards the vertical so that the rear edge describes a curve with two reverse points and the air flow is collected and concentrated upwards.</p> |
