2023 Honda CRF450X suspension sag & service guide
By the Garagely suspension teamUpdated 2026-07-28
For the 2023 Honda CRF450X (enduro / off-road), aim for fork rider (race) sag of 30-33% of travel and fork static sag of 10-15%. At the rear, target shock rider sag of 30-35% and shock static sag of 10-15%. These are percentage-of-travel starting points for the bike's discipline, not exact millimetre settings. Set sag first, then fine-tune the clickers from the stock baselines below, and re-check after any change.
Starting points, not exact settings. Sag targets and spring-rate estimates are reference values that vary by rider weight, model, and conditions. Verify against your owner's manual, dial them in to your own feel, and re-check after any change. Suspension affects handling and safety; consult a qualified suspension technician if unsure.
