Yamaha Lowering Spring Rate: 2003 WR250F

I would be grateful if you can help with setting suspension and sag on my wr250 2003. I am a little under 14 stone and 5 1/2 feet tall.

The stock 2003 WR250F spring is a 4.8kg. At nearly 14 stone you need a spring of 5.6kg to achieve proper sag BEFORE a YamaLink is installed. WITH a YamaLink at 14 stone a spring rate of 5.9 kg or closest is recommended.
