The 999cc inline-four 16-valve ShiftCam engine was measured in the 2022 M 1000 RR on our in-house dyno last year. Despite its lack of engine changes, we wanted to run the 2023 Cycle World Ten Best Superbike on our in-house Dynojet 250i dynamometer to see how the current model compares to its predecessor. Before hitting the Cycle World dyno, the 2023 BMW M 1000 RR weighed 432 pounds on our automotive scales. On the dyno, the bike produced 189.4 hp at 13,220 rpm and 79.2 lb.-ft. of torque at 11,000 rpm. For reference, the 2022 model produced 179.2 hp at 13,960 rpm and 76.3 ib.-ft. of torque at 9,480 rpm. With no physical changes to the engine from 2022 to 2023, the increase in power is interesting as BMW says there are no changes in mapping. And for those shopping in North America, the restricted US model produces less peak power than the European model at a lower rpm, according to BMW.
