Rake vs Trail - please explain? | Indian Motorcycle Forum More rake does two things: one, it makes the wheelbase longer, and two, it generally increases a motorcycle's trail. 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 ... PDF Rake and Trail - Frankenstein Trikes On a sport bike, the rake might be 26°, whereas a long chopper's rake would be more like 45°. To measure trail, make a straight line down from the center of the front wheel's axle to the contact point and another line following the steering axis (drawn along the center-line of the neck), both extending to the ground. Understanding Motorcycle Chassis Geometry | Motorcycle Mojo Three basic measurements have an important influence on handling: wheelbase, rake angle and trail. Wheelbase is simply the distance between the front and rear axles. Rake angle, sometimes called caster angle, is the angle of the steering head (steering axis) from vertical, measured in degrees. Wheelbase and rake are readily visible when looking ...

RAKED TRIPLE TREES: 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 TO MEASURE CORRECT TRAIL Motorcycle Workshop. Part 1: Chassis Geometry - Yamaha Part Trail is defined as the distance between the centre of the front tyre's contact patch and the point where the steering axis meets the ground. (See figure 3. 1) Virtually every motorcycle and bicycle ever designed has a trail value, and this is what gives the front wheel a caster or self-centring effect when in motion. A Quick Guide to Motorcycle Rake, Trail and Offset, Part 1 Rake, trail, offset. These three are the most important concepts governing the rideability of any motorcycle. The offset may be absent in certain models, but where it is being used, it helps to ... RB Racing Rake and Trail Calculator Harley-Davidson motorcyles can be raked and turned into the most radical choppers. Use this calculator to see what the chassis, rake, forks and triple clamps have to do with your magical "trail" figure. Pictured is a Big Dog K9 which has 39 degrees of rake, 3 degree raked trees, and 12" over forks. The result is 4.35" of Trail.

Trail (B) is measured in distance (inches or millimeters) between the point ... Downloads - Motorcycle Data Acquisition -Data For Motorcycles Download the Motorcycle Rake and Trail Calculator here: rake_trail_calculator_v3-0.xls. Thrust Chart Thrust is a measure of actual driving force delivered to the motorcycle's rear wheel, and is calculated as torque multiplied through the primary ratio, internal transmission ratios, secondary ratio, and over the radius of the rear tire. Motorcycle: Front Geometry - Motorbikes - Suspension Secrets Front Geometry. There are 3 main areas of geometry for the front wheel. They are: Offset. Rake. Trail. Offset is the distance from the steering axis to the centre line of the front axle. Alternatively it is the distance from the steering stem to the fork centre line. The diagram below shows the offset distance of the front wheel geometry. The Flying XS: Rake & Trail Raked Triple Trees-- In order to bring trail figures back into line, triple trees with raked steering stems can be used. Expressed in degrees. Usually adjustable in 3, 5, and 7 degrees of rake. Diameter of front tire. 21" front typically 27.60". 19" front typically 26.10". 16" front typically 25.30".

Motorcycle Rake, Trail and Offset Explained - MotoShark.com When riding a motorcycle, the suspension travel and braking will also substantially alter the trail and rake. If you brake hard on the front, for example, the suspension will compress under dive and decrease the rake and trail, and most probably induce wobble in the machine.

Trail - Home | Zero One Racing | Motorcycle Chassis and ... Rake angle - Increasing the rake will increase the trail and vice versa. The rake angle is the angle of the steering axis from vertical. Because the rake angle is influenced by the amount the front and rear suspension is compressed, the rake (and therefore the trail) is constantly changing throughout a lap.
