What is one effect of installing a larger rear sprocket on a motorcycle?

Installing a larger rear sprocket on a motorcycle primarily enhances acceleration. This modification increases the gear ratio, which means more torque is delivered to the rear wheel during acceleration. As a result, the motorcycle can accelerate more quickly from a stop or when increasing speed. While this may come at the cost of top speed—since a larger sprocket can limit the maximum achievable speed—riders often value the improved responsiveness and quicker acceleration for performance riding and racing scenarios.

The other possible outcomes, such as increasing top speed or improving fuel efficiency, generally do not align with the effects of a larger sprocket. Similarly, while weight reduction can affect performance, changing the sprocket size alone does not directly influence the overall weight of the motorcycle.
