I went through water that was higher than the air intake on the CB500x. I had to go fast enough to create a wake. If I would have lost momentum, it would have sucked water into the intake, and that CB likely would have been abandoned in KY.
At one point, I had so much mud stuck to the tires that the front wheel wouldn't turn.
There was 500 foot(?) incline that was about a 35-40% grade where the trail was made up of rocks the size of baseballs. I made it about half way up before I lost all forward traction and was just shooting rocks downhill with my rear tire.
