RR stands for maximum power: with 140 hp at 13,100 revs / min and a maximum torque of 86 Nm at 10,100 rpm / min generated by the presence of two injectors per cylinder. A package specifically developed to retain the riding dynamics and sheer exhilaration of the models prior to the introduction of the new restrictive emission regulations. The result is astonishing; a true technological leap with a refined engine cylinder head developed for noise suppression to the benefit of augmenting ‘permitted’ sound by MV: namely those generated by the combustion. With the introduction of new components such as a harmonic damper, a new mechanical cam-chain tensioner, new camshafts, new valve guides, all completely redesigned and utilizing new materials to minimize stresses and vibrations. Noise reduction also extends to the side covers of the engine, which also act as engine protectors. An entirely new countershaft, starter motor, and primary gear drive, are aimed at improving the reliability. The designs of the transmission gears are also redesigned to achieve better meshing and therefore smoother transitions.
