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 trail affect motorcycle handling?
Less trail reduces steering effort and high-speed stability, while more trail increases straight-line stability while increasing turning effort. As with rake, sportier tend to have less trail, while cruisers tend to have more trail.25 мая 2017 г.
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.
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.”
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.
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 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 do you lower the trail on a motorcycle?
To decrease rake, which also decreases trail, you can install a smaller diameter tire, or slide the fork tubes up in their clamps to give them a steeper angle—a trick many racers use to make their bikes turn quicker—or install longer rear shocks.
What does trail mean on a bike?
How do you calculate bike trails?
To measure the trail of a bicycle, draw an imaginary line that extends through the steering axis (i.e. through the length of the headtube). Ignore the fork. Draw another line that passes through the front axle and is perpendicular to the ground. It will touch the ground at the center of the front tire’s contact patch.
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.
