EBC offers a clutch spring kit from the CSK line, specially developed for the 2008–2016 Yamaha WR 125 and YZF-R 125 models. Made of high-strength steel, these springs provide consistent and long-lasting tension, ensuring firmer and more precise clutch engagement. They effectively reduce slippage, improve engine torque transmission, and optimize the bike’s responsiveness. Their robust design offers greater reliability and extends the service life of the clutch system, whether for street riding, sport riding, or off-road use.
