For best safety and convenience, cars are fitted with active cruise control. Once the preserve of luxury vehicles, this technology has filtered down to more affordable machinery. For example, it is standard fit on Suzuki Swift Sport for around $30,000.

Motorbikes have been fitted with cruise control for quite some time, but never active cruise...until now. BMW Motorrad has developed Active Cruise Control (ACC), and will soon offer this rider assistance system, providing what the firm describes as a “new, comfortable riding experience”.

Developed with technical partner Bosch, the experience with BMW cars was used in the design of the unit for motorcycles. The ACC automatically adopts the speed set by the rider and also the distance to the vehicle in front. The following distance can be varied in three stages by using a button on the left switch block. Settings are displayed on the TFT instrument cluster.

ACC has two overall control characteristics, comfortable or dynamic, and change of speed is adapted accordingly. The distance control can also be deactivated in order to be able to use the Dynamic Cruise Control (DCC).

In this configuration, the speed is reduced by the ACC so a comfortable lean angle in corners is the goal. With an increasing lean angle, the braking and acceleration dynamics are limited to maintain smooth progress.

The BMW Motorrad ACC is a rider assistance system that leaves the ultimate responsibility with the rider, the reason being ACC only responds to moving vehicles. Those stopped at traffic lights, for instance, are not detected by ACC and so in such circumstances the system is deactivated as soon as the rider starts braking.
