Most likely cause
BasicPreload / rebound wrongly set
The first, free reflex: set the spring preload (and rebound if present) to your load. Too little preload bottoms out and sags the bike; too much makes it hard and skittish. Aim for the recommended static sag (about a third of the travel). 🟢 Simple adjustment with the original tool. This tool helps you understand what's going on -- it doesn't replace a certified mechanic.
How to make the repair yourself
🟢 Within reach of any rider: no advanced mechanical skill or specialised tooling needed.
- Locate the preload adjustment: a stepped collar on the spring (a C-spanner or supplied tool) or a hydraulic knob on recent models.
- Measure the sag: unladen height (bike on a rear stand), then bike on its wheels with you in riding gear and position; the sag should be about 30-33% of the travel.
- Increase the preload if the bike sits too low / bottoms out; decrease it if it stays high and harsh.
- Adjust for the load: more preload two-up or loaded, less solo. Note your settings.
- If present, set the rebound: the bike should return without bouncing or staying packed down after a bump.
⚠️ This tool helps you understand what's going on with your motorcycle; it doesn't replace the inspection or judgment of a certified mechanic. If in persistent doubt, if a safety-critical part is involved (braking, steering, bearings, transmission), or if the problem keeps recurring, have the diagnosis confirmed at a workshop before doing any work.
