Suspension Setup

This tool helps you correctly measure and set your motorcycle suspension sag using a structured, step-by-step process.

By entering your bike’s suspension travel, rider weight, and basic measurements, you’ll get recommended sag targets based on proven suspension setup principles.

The goal is to help you achieve:

Proper balance and stability
Improved comfort and traction
Correct preload adjustment before fine-tuning damping

This is a general setup tool, suitable for street, track, and off-road use.

Results are based on industry-standard sag percentages and should be used as a starting point.

Final tuning should always be done based on riding feel and conditions.

Measure and set your motorcycle sag step-by-step. Enter travel (mm) to compute target sag ranges from % travel. Use this as a baseline, then fine-tune damping on a test ride.

Tip

Select mode + enter travel.

Disclaimer: Targets are general guidelines. Ideal sag depends on travel, spring rates, linkage design, rider position, and load (gear/luggage).

Guidance: If you can't reach targets without near-max preload, consider changing spring rate. Set sag first, then tune damping.
