Honestly, weight means little to me except on the drag bike.
Apart from low-speed riding in a parking lot etc, the weight has little feel to me.
My father's 07 EG was heavy as heck as far as curb weight went, but handled quite well on curvy roads. His next, 09 or 10, if I remember right, didnt feel quite the same. They changed something over those couple years and the bike didnt feel as nimble.
But yes. not moving, once they start you better catch them soon or just step away, as even a 400lb sportbike is going to hurt your back if you try to save it once it gets to a certain point
