Note from RaceTech regarding the Fork Springs for CRF300L:

Measure oil volume - not level. Stock: the left leg is damping only, right leg is spring only. The stock spring is way too soft.

RT spring kit adds spring to the left leg and retains the stock spring in the right leg. This increases the total spring rate. RT spring calculator calculates only the new spring you are adding to damping leg. RT Fork Spring Kit includes an adapter kit to add a spring to the Damper leg. Total spring rate is a combination of both springs. No need to disassemble the right leg unless its due for a rebuild or you want to put in good oil. Custom Spring required for stiffer rates. Fork Spring Spacer 330mm long.
