Wiseco CSK050 Clutch Spring Kit CRF250R Replacement Springs

The Wiseco CSK050 Clutch Spring Kit is a direct-replacement clutch spring set engineered to restore and improve clutch performance on the Honda CRF250R. Designed for riders who demand consistent, reliable clutch engagement, this kit replaces worn or fatigued OEM springs with a stiffer, higher-performance alternative.

Key Features:

• Premium steel construction — springs are manufactured from high-quality steel for durability and long service life
• Shot-peened finish — surface treatment improves fatigue resistance and extends spring life under repeated high-load cycling
• Heat-treated — thermal processing ensures consistent spring rate and prevents premature relaxation or loss of tension
• Stiffer spring rate — firmer than stock springs to provide a more positive clutch lockup and reduce clutch slip under hard acceleration
• Direct OEM replacement — designed to drop in without modifications

Whether you're rebuilding a worn clutch or upgrading from soft factory springs, the Wiseco CSK050 delivers the positive engagement and reliability needed for competitive motocross and trail riding. Pair with Wiseco clutch plates and a forged clutch basket for a complete clutch system rebuild.
