New Yamaha R1 patent shows active aero technology

In a recent document, Yamaha has applied for a patent showcasing a new active aero package for the R1, aimed at improving cooling and high-speed performance through drag reduction.

1. Significant changes to the side panels
2. Increased cooling performance tailored to various use cases
3. Combination of the systems can enable higher fuel efficiency and reduced emissions

Yamaha is aiming for improved cooling as well as drag reduction

Two versions of the designs have been proposed

The patent application detailing Yamaha’s take on active aero doesn’t show any brand-new technology, and the Moto Guzzi V1000 Mandello already uses a simple form of active aero. However, Yamaha’s application is more performance-oriented. Simply put, the new bodywork incorporates air outlets that automatically open or close depending on the bike’s needs.

The new side panels are more enveloping compared to the previous, rather open design, and include outlet ducts to let out hot air once it has passed through the radiator. 

Closing these outlet ducts also provides aerodynamic benefits by reducing drag, which will increase high-speed performance.

Yamaha’s patent shows two different versions, both functioning in a similar manner. One version consists of a singular large outlet duct on either side of the fairing with variable vanes, while the second has a pair of outlets on each side, which should result in higher cooling potential and greater control over airflow.

The two movable vanes are operated by a simple electric step motor and belt drive mechanism that rotates them to the position desired by the bike’s ECU. This means Yamaha can afford a design that doesn’t add significant bulk and weight to the motorcycle. The system will be directed by a variety of data, including engine temperature, outside air temperature, throttle position, vehicle speed, and more.

With the use of such technology, Yamaha could alternate between prioritising engine cooling and aerodynamics as and when possible. Doing so will have both performance and efficiency benefits – the latter will also result in reduced emissions. A technology like this on a road bike could benefit its racing initiatives as well.
