Rider Weight Options
Choose your spring rate for a dialed-in ride:
-
Medium (140 – 180 lbs) → 4.0 / 4.0 springs
-
Heavy (180 – 220 lbs) → 4.0 / 4.4 springs
(Weight range excludes gear — add ~15 lbs for riding kit.)
SETTINGS NOTE: Settings are number of clicks from the closed position (full clockwise). Once they are in the closed position, back them out (counter-clockwise) according to the number of clicks indicated in the chart above to get you to factory settings.
CMX Tune Starting point notes:
- Assuming neutral riding position, and 15 lbs gear
- Weights of upgrades (battery, controller, etc) to be added to rider weight
- Riders close to a weight cut off need to adjust preload to compensate
- Very aggressive/pro riders to consider +1 weight class and drop preload to get sag. Especially if in the upper range.
- Rider preference and riding conditions may require a different setup
Example:
- 160lb rider without riding gear, plus upgraded battery (20 additional lbs)
- Weight calculation 160+20=180
- Aggressive rider = Heavy tune with low preload
- Relaxed rider = Medium tune with high preload
The Bottom Line
The F43 CMX isn’t just stiffer or stronger — it’s the ultimate front-end upgrade for light E-Motos. From big-hit stability to razor-sharp precision, this fork transforms your ride into a race-ready machine that eats terrain alive. Whether you’re chasing podiums or just want the best of the best, the CMX Tune delivers.
