What can increase the risk of a motorcycle fall while driving through road bends?

Your answer is correct because an oil spill and a bump on the carriageway both increase the risk of a motorcycle falling in bends. Oil makes the road slippery, reducing tire grip, which is especially dangerous when leaning into a turn. A bump can unsettle the motorcycle’s balance and cause loss of control. In contrast, a carriageway that inclines towards the inside of the bend (a banked curve) generally helps stability and reduces the risk of falling, so it is not a risk factor. Understanding these road conditions helps motorcyclists adjust their speed and riding technique to stay safe in bends.
