This dirt bike suspension tuning guide provides some guidance on what actions to take depending on what problems a bike's suspension exhibits. Realize that proper tuning can only be acheived with proper riding technique, correct spring rates and suspension that is properly maintained. If the suspension is not working correctly to begin with, tuning will have little if any benefit. The same is true if a rider exhibits poor body position while riding. Please refer back to Suspension Adjustment Basics for an overview.
Understeer means that a motorcycle is slow to turn. In this case, the bike may tend to drift wide despite the effort of the rider.
Oversteer means that a motorcycle turns too quickly. In this case, the bike may tends to turn too sharply (or dart to the inside) which can disrupt a smooth, controlled arc.
Washing out refers to the front end loosing traction while cornering, causing the rider to lose some or all control.
Head shake is when the front end of the motorcycle deflects side to side in a continuous manner.Problem occurs slowing down
Rear end swapping means the rear of the bike deflects side to side.
The suspension has a jarring effect. Impacts are transmitted to the rider and there is a lack of plusness.
The suspension stroke progressively shortens across a series of bumps or whoops because it is unable to return quickly enough after each successive hit.
Upon landing, after the suspension completes compression stroke, the bike springs up rather than returning to ride height in a controlled manner.
The suspension exhibits a jarring effect. Impacts are transmitted to the rider.
Note: Suspension could also be bottoming out. See "Suspension bottoms too easily".
