MX race day - the setup workflow

Night before

Check sag with full gear (race sag per your bike's target, typically 100-106 mm - see your bike page), set tire pressures for the expected terrain (standard ~0.83 bar; wet or sandy 0.8; hardpack up to 0.9-1.0), check spokes, chain tension, clickers at your baseline. Write your baseline down.

Track walk / first practice

Morning tracks are usually WATERED and groomed: tacky, grip up - your baseline or one click firmer works (LAISA tag: watered, -1 compression (one click in, firmer) is for soaked spots; tacky prep needs nothing). Identify: jump faces, braking bumps (none yet - they come), sand sections, ruts forming.

Between sessions (the loop)

  1. ONE change at a time, same reference lap, take notes (golden test rule).
  2. The track gets ROUGHER every session: braking bumps and acceleration chop build. Expect to OPEN compression and speed up rebound (+1/+1, one click out each) as the day progresses - the morning setup is usually too stiff for the afternoon.
  3. Sand sections deepen: if the rear POGOES or kicks in sand whoops the rebound is too fast - slow it one click (clicker in); if the rear PACKS down and stays low the rebound is too slow - speed it up one click (clicker out). Sort the rebound before you reach for compression.
  4. Re-check tire pressure after sessions - pressure rises 0.1 bar warm; judge against your COLD target.

Race

Moto 1 on your refined setting. Between motos only correct clear faults (kicking, packing, front tucking - see the symptom matrix), never experiment. After the day: write down the final setting plus track + conditions - that is your reference for next time (and your LAISA garage entry).

Note: clicks are counted out from fully closed. + means further open (less damping), - means turning in (more damping).
