Question: Why do you stretch a motorcycle?

Stretching a sportbike lowers its stance, which can be further lowered by additional suspension modifications. A lowered stance improves traction, meaning less power is wasted and more power is available to push the bike forward.

Can a motorcycle be too big?

A bike is too big if you can’t place both feet firmly and comfortably flat on the ground while astride it. It’s too powerful if you’re a newbie rider (less than a couple hundred hours ride time) and it’s over 60 hp and is faster than 0–60 in 4 seconds.

Why are motorcycles stable?

The gyroscopic forces created by a moving wheel give it stability and help keep it upright. One of the other discoveries scientists made early on is the physical property that the front wheel of a bicycle touches the ground a short distance behind the axis of steering.

Is it bad to stretch a motorcycle?

Stretching a bike’s frame dramatically affects the way it’s ridden. … Because it helps the bike go faster for racing, assuming it’s done right. More specifically, it doesn’t make the bike faster from an increase in horsepower or torque, but by changing how the bike interacts with the road and the driver.

What does a swing arm do on a motorcycle?

A swingarm, or “swinging arm” (UK), originally known as a swing fork or pivoted fork, is a single or double sided mechanical device which attaches the rear wheel of a motorcycle to its body, allowing it to pivot vertically.

How much trail is too much on a motorcycle?


If the trail is more than 6 inches the bike will handle sluggishly at high speeds. It will seem almost too steady. You will have trouble balancing the bike at lower speeds or on winding roads. It will feel generally sluggish and clumsy.

What is the ideal trail for a motorcycle?

More trail is nice at high speeds (motorcycles usually have 80 mm of trail) but can feel sluggish at slower speeds. Head angle also influences wheelbase and front center, which affect weight distribution. Ideally, a rider should have 45% of the bike + rider’s weight on the front wheel and 55% on the rear wheel.

Why do motorcycles want to stay upright?

A bike remains upright when it is steered so that the ground reaction forces exactly balance all the other internal and external forces it experiences, such as gravitational if leaning, inertial or centrifugal if in a turn, gyroscopic if being steered, and aerodynamic if in a crosswind.

Why do motorcycles lean to turn?

Usually a turn is initiated by steering in the opposite direction. If you want to turn right, you steer briefly to the right. This moves the track of your wheels right, out of the center of gravity. In reaction to this, the bike leans left, which compensates the centrifugal force.

Why do bikes not fall over?

The most common explanation is that the wheels on a bike act as a gyroscope, preventing the bike from falling over. A bike was constructed with counter-rotating wheels to test this. The bike had two front wheels, one on the ground and rotating forward, and one off the ground rotating backward.
