Even a quick stop may not be enough to keep you from hitting something in your path. A vehicle ahead might stop suddenly or pull out and partly block the lane. You may be able to steer around an obstacle quicker than you can stop. The only way to avoid a collision could be with a quick turn.
The key to making a quick turn is to get the motorcycle to lean quickly in the direction you wish to turn. The sharper the turn, the more the bike must lean.
Stay in your own lane in an emergency. The moment you change lanes, you risk being hit by another vehicle. You should be able to squeeze by most obstacles without leaving your lane. This is one time when the size of the motorcycle is in your favour. To avoid being hit, you can go into spaces too small for a car.
