The JBS 2025 Kawasaki KRX 1000 Clutch Weights are designed, tested, and made in house at JBS for the newly designed 3-arm clutches with clutch weight shims.
These weights are built to help stop your clutch weights from chewing up the sides of your aluminum primary. Steel vs. aluminum? Your clutch weights can destroy the KRX primary over time. These weights are built as the ultimate cure with steel-on-steel wear.
James from JBS has put hundreds of hours into designing and testing multiple weight profiles and shapes for the KRX 1000. These are the end result of those long hours and serious attention to detail. Made in the USA, these clutch weights are built for strong performance, long-lasting wear, and adjustable tuning for different riding styles.

Important Notes
JBS recommends using the clutch weights with the primary and secondary spring upgrades.
The weights are designed to run with or without a primary spring.
It is best to run without the factory primary spring for best belt life, because the belt isn’t as tight during back shifting with the factory primary spring installed.
