Honda RC 51 weight overview
This is neither unusually light nor extremely heavy. For most riders the practical weight question is more about seat height, center of mass and low-speed balance than the scale number alone. The comparison uses dry weight because a usable wet/running figure was not supplied, so the actual ready-to-ride motorcycle will be heavier.
