CRF300L / CRF300L Rally Race Tech Fork Spring Install & Setup Guide (2021-2026)

Upgrading your Honda CRF300L or CRF300L Rally with a Race Tech fork spring kit is one of the most effective ways to improve front-end performance. This kit corrects the overly soft stock suspension, improves braking stability, and delivers better control on and off-road.

✅ Fits

• Honda CRF250L
• Honda CRF250L Rally
• Honda CRF300L (2021-2026)
• Honda CRF300L Rally (2021-2026)

💡 How This Kit Works (Important)

The CRF300L uses a split-function fork design:

• Left fork leg: Damping only
• Right fork leg: Spring only

The stock setup is significantly under-sprung. The Race Tech kit adds a spring to the damping leg, increasing total fork spring rate and improving balance. :contentReference[oaicite:1]{index=1}
