In terms of strengths, the BMW S 1000 RR 2014 is praised for its powerful engine, superior electronic package, excellent gear shift assistant, and versatility for both track and road use. Despite its high performance, it is considered an easy bike to ride.

On the other hand, the BMW M 1000 RR 2021 is commended for its smooth overall package, strong brakes, precise chassis, and high-quality details that are a pleasure to admire in the paddock. It has a great throttle response, a strong torque curve, and a seamless transition from the load mode to the push mode.

However, both models have their weaknesses. The BMW S 1000 RR 2014 is criticized for its steep price increase in the fully equipped version and its slightly complicated stability. The optional packages are seen as profit-maximizing rather than customer-benefiting.
