Yes, the bike is going to turn the wheel, I'm not saying that it's not going to turn. You may be like this hand grip for dirt bike guide I'm just saying that you're really not force it. The effect on a dirt bike or a downhill bike is even more pronounced with its higher angles, making it even at low speed but more self-stable.
