Supertech 05-07 KTM 250SX-F Single Conical Valve Spring - Single

If you're rebuilding the top end of your 2005-2007 KTM 250SX-F, you'll need reliable valve springs to ensure proper valve operation. This single conical valve spring from Supertech is designed to replace the original component, helping to maintain the correct tension and timing for your engine's valves.

This spring is constructed to handle the demands of the engine, ensuring that the valves close securely and consistently. Its conical shape is a specific design choice that can help reduce the spring's tendency to vibrate at high RPMs, contributing to more stable valve train performance. When installing, it's important to follow the manufacturer's specifications for proper seating and tension to get the most out of this part.
