Mechanical Trail Solution

STEP 0: Pre-Calculation Summary
Formula Used
Trail = (Front Tire Radius*sin(Rake Angle)-Triple Clamp Offset)/cos(Rake Angle)
Tm = (R*sin(α)-d)/cos(α)
This formula uses 2 Functions, 4 Variables
Functions Used
sin - Trigonometric sine function, sin(Angle)
cos - Trigonometric cosine function, cos(Angle)
Variables Used
Trail - (Measured in Meter) - Trail is defined as the distance the front tire’s contact patch “trails” the imaginary point where the steering axis intersects the ground.
Front Tire Radius - (Measured in Meter) - Front Tire Radius is the radius of the front wheel of the motorcycle.
Rake Angle - (Measured in Radian) - Rake Angle is the angle of orientation of tool’s rake surface from the reference plane and measured on machine longitudinal plane.
Triple Clamp Offset - (Measured in Meter) - Triple Clamp Offset the difference between the centerline of the forks and the centerline of the steering head.
STEP 1: Convert Input(s) to Base Unit
Front Tire Radius: 600 Millimeter --> 0.6 Meter (Check conversion here)
Rake Angle: 5 Degree --> 0.0872664625997001 Radian (Check conversion here)
Triple Clamp Offset: 22 Millimeter --> 0.022 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Tm = (R*sin(α)-d)/cos(α) --> (0.6*sin(0.0872664625997001)-0.022)/cos(0.0872664625997001)
Evaluating ... ...
Tm = 0.0304091616895909
STEP 3: Convert Result to Output's Unit
0.0304091616895909 Meter -->30.4091616895909 Millimeter (Check conversion here)
FINAL ANSWER
30.4091616895909 Millimeter <-- Trail

What is Ground Trail?

Ground Trail is the horizontal measurement along the ground from the front contact point to where the steering axis intersects the ground.

How to Calculate Mechanical Trail?

Mechanical Trail calculator uses Trail = (Front Tire Radius*sin(Rake Angle)-Triple Clamp Offset)/cos(Rake Angle) to calculate the Trail, Mechanical trail is the perpendicular distance between the steering axis and the point of contact between the front wheel and the ground. It may also be referred to as normal trail. Trail is denoted by Tm symbol.

How to calculate Mechanical Trail using this online calculator? To use this online calculator for Mechanical Trail, enter Front Tire Radius (R), Rake Angle (α) & Triple Clamp Offset (d) and hit the calculate button. Here is how the Mechanical Trail calculation can be explained with given input values -> 30.40916 = (0.6*sin(0.0872664625997001)-0.022)/cos(0.0872664625997001).

FAQ

What is Mechanical Trail?
Mechanical trail is the perpendicular distance between the steering axis and the point of contact between the front wheel and the ground. It may also be referred to as normal trail and is represented as Tm = (R*sin(α)-d)/cos(α) or Trail = (Front Tire Radius*sin(Rake Angle)-Triple Clamp Offset)/cos(Rake Angle). Front Tire Radius is the radius of the front wheel of the motorcycle, Rake Angle is the angle of orientation of tool’s rake surface from the reference plane and measured on machine longitudinal plane & Triple Clamp Offset the difference between the centerline of the forks and the centerline of the steering head.
