i recommend using your wheel. i find my wheel easier to control then my xb1 controller. i had a very hard time at first not using weight forward and back with the wheel, but using x360ce, i was able to assign left stick forward, and left stick back to 2 buttons on my wheel. the 2 buttons are on my upper right side, pretty much where my right thumb is. so i hold one button for lean forward and one for lean back. and since my wheel's degrees of rotation is set to 100, i keep my hands in one place the whole time(opposed to hand over hand with higher degrees of rotation). since i have got used to it, i noticed the bikes are very stable now.
also, i have my ingame steering sensitivity set to 100%. i think it made a huge difference in how fast the bike hikes over from side to side. i could never do 100% with a controller, but can manage it with my wheel. try it out, man. you won't be disappointed.
