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. Under normal operation, this contact point is always some distance behind the projected line—somewhere between 2 and 4 inches (5–10 cm).
How is rake and trail calculated?
Rake– The angle in degrees of the steering neck from the vertical. Fork Length– The distance between the top of the fork tubes to the centerline of the axle. Diameter of the front tire. Trail: Distance defined by vertical line from axle to ground and intersect of centerline of steering neck and ground.
How are motorcycle rakes measured?
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.
What is the trail on a motorcycle?
Trail 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 rake and trail affect motorcycle handling?
The bottom line here is that the more rake and trail we have, the more stable the bike will become, although both steering and maneuverability may suffer for it. Conversely, when rake and trail are reduced, the bike will steer quicker and become more maneuverable, though it’s usually at the expense of stability.
How much rake is too much on a motorcycle?
As in the case with rake, the amount of trail varies with the type of motorcycle. The 3.5-6 in range is what the experts say is the perfect amount.
How is rake calculated?
The above schedule shows the rake at $0.01 for every $0.18 in the pot, up to a cap of $2.00 for 3 players. The rake is calculated as $40.00/$0.18*$0.01= $2.22.

How is fork rake calculated?
Measure the height of the fork dropout off the top of the flat surface (Dim A). Measure the height of the center of the steerer tube off the top of the flat surface (Dim B). Subtracting Dim B from Dim A will result in the fork offset or rake.
What difference does fork rake make?
Fork offset — also known as rake — is the distance between the axle and a straight line through the head head tube. Offsetting the fork more (increasing offset) pushes the axle further in front of the head angle. Reducing the offset — which is what many bike designers are doing today — pulls the axle closer.
How do you measure a Springer front end trail?
The first measurement is the radius of the front wheel and tire. The distance from the ground straight up to the center of the axle is the (A) distance. The best way to measure this is to make sure the tire is properly inflated and the wheel is completely vertical when looking at it from the front or back.
How does trail affect handling?
Trail is a combination of the head tube angle and the fork rake and can be thought of as the tyre contact point trailing behind the steering axis. The short explanation is a small amount of trail equals a ‘fast’ handling bike, while greater trail equals a ‘slow’ handling bike.
How fast can a 250cc motorcycle go?
The average 250cc motorcycle will have a top speed of around 130 km/h or 80 mph. The weather and road conditions will have an impact on the top cruising speed as well as the load being carried.
