Hi @iggy
Sorry for taking so long to reply, I went on a vacation and did not check the posts, I ride for 35 years, yes I am already in my 50's and never tried on a road bike, I used to have an old IT490 two stroke off-road, which was very light and I did flip backwards a few time of it, but being light you just stepped off to the back and kept the bike upright. The ZX9 will be to heavy to do it.
