Ferrea 04-10 Honda CRF 250R 21.50mm OD 15.10mm ID Single Valve Springs - Set of 2

If you're rebuilding the top end of your 2004-2010 Honda CRF 250R, you'll need reliable valve springs to ensure proper valve operation. These single valve springs from Ferrea are designed to replace the stock springs, helping to maintain the correct tension and timing for your engine's valves.

Ferrea uses well-built materials to create these springs, aiming for consistent performance. The springs measure 21.50mm in outer diameter and 15.10mm in inner diameter, fitting the specific requirements of the CRF 250R engine. Having the right valve springs is crucial for preventing valve float, especially at higher RPMs, and ensuring your engine runs smoothly.

This set includes two valve springs, which is what you'll need for a single cylinder. Make sure to check your service manual for the correct installation procedure and any other components you might need for your valve train rebuild.
