Product Overview

The BRT Racing Super Clutch Spring from Bintang Racing Team is a premium aftermarket upgrade engineered to maximize power delivery and acceleration for high-performance motorcycles like the Suzuki GSX-R, Yamaha R15 (V3/V4), and Yamaha XSR 155. Manufactured using high-quality Swedish steel wire (Oteva 75 Garphyttan) and processed through an advanced hot-wire system, these springs provide consistent elasticity and exceptional performance even under extreme temperatures. This kit increases overall engine torque by 10% and is roughly 10% harder than stock options, minimizing clutch slippage during aggressive shifts. Designed for both everyday street touring and competitive track racing, it extends the service life of your clutch discs by up to two times while delivering a highly responsive, positive lever feel.
