Questions & Answers


Im looking for a softer spring for a lighter rider. Would this be softer then the stock spring i have on a 2013 crf250r?

By Andy M

5.2 kg/mm is the stock spring rate for a 2013 Honda CRF250R. A 180 pound rider under normal trail conditions would be suited to a spring rate of 5.2 kg/mm. 150 lb rider would want a 4.8 kg/mm, 135 lb rider would be a 4.6 kg/mm. That should give you a better idea of what spring you may need for your ride.
