We have developed Akrapovic Racing and Evolution systems which offer even more muscle for the sporty German K1200S and naked K1200R. And in addition to improved performance, they also deliver a major aesthetic enhancement, as the HEXAGONAL muffler works extremely well with the lines of both motorcycles. You will also save almost 7 kg compared to stock system.

Measurements of the Akrapovic EVOLUTION system on the BMW K 1200 S, R (without muffler insert):

Power & Torque: since the two bikes are closely related, the shape of their power and torque curves are very similar. Only their outputs are different, with the S model being a bit more peppy. Since these are complete systems they are designed to increase power and torque at the top of the range. Thus max. increased power for the S model is 9.3 HP at 10550 rpm and for the R model 7.3 HP at 9960 rpm.
