Variable electronic throttle control systems can be found on an increasing number of motorcycles from manufacturers such as Aprilia and Ducati. These systems allow a rider to choose engine response and power to best suit riding conditions. A "Rain" mode, for example, may reduce both horsepower and torque while flattening out the torque curve. This will allow for very smooth power delivery and limit the chance of losing traction at the rear wheel. On the side of the spectrum, a "Sport" mode may maximize throttle response and give very abrupt power delivery within a certain RPM range. Variable electronic throttle control increases a bike's versatility, making it suitable for a wider range of riders and riding conditions.
