Got mine checked at the local garage, it’s 181 kg with a full tank.I get your point, but it feels way lighter than the figure would have you think. Also be careful with weights, it's 178kg dry, so 12kg more than a certain KTM, BMW actually list reasonable wet weights unlike some manufacturers...
47 kg is a huge difference. I’m a stickler for light bikes though and it’s probably not an issue for normal people.
The local mechanic always thought I was nuts and I think I’ve just proven it to him when I explained it was to prove a point to people on the internet.
