How is a motorcycle rake determined?

Rake (also called caster) is the angle of a motorcycle’s steering head of the frame (A). … Trail (B) is measured in distance (inches or millimeters) between the point of the front wheel’s contact with the ground and a line drawn through the axis of the steering head.

How is a motorcycle rake measured?

OFFSET: Centerline of the top steering neck to the centerline of the top of the fork tubes. RAKE: The angle in degrees of the steering neck from vertical. FORK LENGTH: The distance between the top of the fork tubes to the centerline of the axle.

What is rake on a motorcycle frame?

Rake is the angle, in degrees, that the steering head of the frame—not the forks—is tilted back from the vertical. For example, the rake angle on all the Harley-Davidson Touring models is 26 degrees.

What is rake and stretch on a motorcycle?

Stretch and Rake:

This repositioning may be done to change the handling characteristics of the motor-cycle, fit the frame to the rider, or more often than not, to give the motorcycle a particular look, i.e. long and low or a high neck.

How does rake affect handling?

The smaller the rake angle, the less effort is required to turn the steering. Though, the motorcycle will be less stable in a straight line. Conversely, a larger rake angle requires more effort to turn but tends to make the motorcycle more stable at high speeds and helps maintain a straight course.

What is the difference between rake and trail?

Rake (also called caster) is the angle of a motorcycle’s steering head of the frame (A). … Trail (B) is measured in distance (inches or millimeters) between the point of the front wheel’s contact with the ground and a line drawn through the axis of the steering head.

How do you measure forks on a motorcycle?

Fork length is measured from the base of the frame neck to the center point of the axle mounting hole. For any off-the-shelf motorcycle this standard measurement for the front forks is considered stock length.

Does lowering a motorcycle affect the handling?

Effects on Handling

Even if you lower your bike by the book, handling can be affected to some degree. “When you lower a bike, you also lower its center of gravity, so it’ll handle a bit better in certain circumstances,” says Langley. “The negative is that your initial ground clearance is decreased.

What is a good lean angle on motorcycle?

If I use a coefficient of 0.7, this would give a lean angle of 35 degrees. However, racing motorcycles can lean over 60 degrees.

How can I improve my motorcycle rake?

Sliding the forks down in their clamps to give them a shallower angle relative to the pavement increases rake and trail, as does installing a shorter rear shock to lower the back of the bike. Rake and trail changes can also be made inadvertently.

What’s the point of stretching 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.

What does trail mean on a bike?

Trail, or caster, is the horizontal distance from where the front wheel touches the ground to where the steering axis intersects the ground. The measurement is considered positive if the front wheel ground contact point is behind (towards the rear of the bike) the steering axis intersection with the ground.

How does ride height affect handling?

Increased ride height: Raises CG, front roll center, and reduces rake. The change will shift weight to the rear, improving the grip of the tires at that end of the car and shifting the handling balance toward UNDERsteer and typically increase aero drag and increase downforce.

What is reverse rake?

reverse rake is when the front of your car sits higher than the rear.

What does ride height rake mean?

Rake refers to the car altitude created by raising rear ride height in relation to front ride height, effectively setting the car up with an upward slope front-to-rear.
