Yamaha YZ450F suspension setup
By Travis Flateau, TBT Racing · from 230+ TBT build sheets, 2018–2026
The YZ450F runs a KYB coil fork and shock. Most riders above average weight need stiffer springs than stock, plus valving tuned to their speed.
| Rider weight | Fork springs | Shock spring |
|---|---|---|
| 150–169 lb | .48 | 5.7 |
| 170–189 lb | .50 | 5.9 |
| 190–209 lb | .50 | 6.0 |
| 210+ lb | .54 | 6.2 |
Year and riding style change the right spring. Treat this as a starting point.
