# What is rake on a motorcycle

## What does rake on a motorcycle mean?

Rake is the angle, in degrees, that the steering head of the frame—not the forks—is tilted back from the vertical. … To better understand this, visualize a motorcycle with 0 degrees of rake, with the forks straight up and down, perpendicular to the ground.

## How is a motorcycle rake determined?

Raise the bike to an upright position, using a tape measure, hold the tape straight down from the front axle to the floor. Put a mark on the floor at that point. Then place the tape parallel to the steering neck, following the angle of the steering neck all the way up to the floor. Put a mark here also.

## How does rake affect handling?

Fork rake or fork offset is a key factor in the handling of a bike. … The amount that the fork is offset from this imaginary line is known as fork rake in road bikes, or fork offset in mountain bikes. Increasing the offset will make steering faster, conversely decreasing it will slow it down.

## What is trail in a motorcycle?

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.

## 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.

## Does lowering a motorcycle affect the handling?

Effects on Handling

“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. Things you used to clear, like curbs or speed bumps, might now be a problem.”

## Can you change the rake on a motorcycle?

One of the most common modifications to our bikes is to lower the rear end. As the rear of the bike goes down the steering head angle steepens increasing the rake and trail. … In order to bring trail figures back into line, triple trees with raked steering stems can be used. Usually adjustable in 3, 5, 7 degrees of rake.

## How does wheelbase affect motorcycle handling?

The longer the wheelbase, more the stability and less the maneuverability; smaller the wheelbase, less the stability and more the maneuverability. … The ground clearance also plays an important role in the handling of the bike, hence even that has to be considered when playing with the wheelbase of the bike accordingly.

## 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.

## 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 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.22 мая 2015 г.

## What is reverse rake?

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

## How fast can a 250cc motorcycle go?

Depending on the type of engine, a 250cc dirt bike comes at a maximum speed of between 55 to 70 mph (90-113 km/h).

## What is the difference between a dirt bike and a trail bike?

The difference between an enduro and a trail riding dirt bike is that enduros are designed more for racing and for speed built with more power and better suspension, while trail riding dirt bikes are meant more for riding through rough and rocky trails and have more strength in the bike for climbing.
