Product Details

The EBC CSK140 Heavy Duty Clutch Spring Kit is designed to replace worn or heat-damaged OEM clutch springs with upgraded performance springs. These premium clutch springs are engineered to be approximately 10% stiffer than stock springs, providing improved clutch engagement and more positive feel during operation.

Key Features:

  • 10% stiffer spring rate than OEM for improved clutch performance
  • Prevents clutch slippage caused by worn or heat-damaged springs
  • Smoother, more positive clutch engagement for better takeoff control
  • Enables faster, more precise shifting under aggressive riding conditions
  • Complete kit includes all necessary springs for installation
  • Direct OEM replacement fitment

The increased spring tension delivers noticeable benefits including reduced clutch slip, crisper engagement, and improved power transfer. While the clutch lever pull will be slightly firmer than stock, the performance gains make this an excellent upgrade for riders seeking better clutch feel and durability. These springs are particularly beneficial for motorcycles used in performance applications or those experiencing clutch fade from heavy use.

Cancelled first order to purchase different exhaust. Although holding time on phone was over an hour I was able to get refund and purchase the one I originally wanted.they need a better phone system but good products at cheap prices

Quick, easy, and excellent description of product. Best prices on the internet!

thanks

Fast and easy

Good so far. No complaints about the service. The service was easy and fast, unfortunately the order was not what I was looking for. My only complaint was that the description on the web site was completely lacking and only the model and a picture were available. This lead me to ordering the wrong thing and ultimately having to send the items back and start my search over again.

quick and easy

nice easy

Best price I could find anywhere. Almost 10% less than my typical sources and the item shipped in less than 24 hrs.<br>
