Honda water cool over 1000cc engine size probably weigh around 250 Kg to 300 Kg. I dropped the bike at the walking speed during the down hill, a private road entrance where we could not ride properly, I had to push the bike while sitting on it and the engine was idling. Then I realized that the bike was so heavy and I could not keep it upright. Eventually I had to drop it to to save my leg/ foot. Fortunatey, the bike was not damaged or scratched. It was a controlled drop. More training needed. If you can sit on it and push with your feet at walking pace, you could have ridden the bike under its own power and it would have been stable. All bikes whilst moving are stable. You can ride at a very slow speed and it won't feel heavy. Also what were you doing riding such a big bike if you were not confident??
