Doug asks about lowering a 2009 WR450F and spring rate for 200 pound rider with YamaLink

"What spring do you suggest for a 200 lb rider on 09 WR450 with the link? Thanks, Doug"

If he's an honest 200 pounds WITHOUT gear put a 6.1kg or closest with a YamaLink and then readjust sag. Given the decision for a 6.0 or 6.2 always go with the heavier spring with a YamaLink. FYI, at 200 pounds without gear and withOUT a YamaLink your customer needs a 5.8kg on a WR450 for proper sag.
