G2 Ergonomics Throttle Tamer Tube 40-4Y-136C for Kawasaki Z900RS

The G2 Ergonomics Street Throttle Tamer Tube uses a progressively shaped cam to alter the relationship between throttle rotation and throttle-body opening. Its reduced-radius cam section from closed throttle to approximately half throttle requires more rotation for smoother low-throttle control, while the radius increases beyond half throttle to maintain near-stock rotation to full throttle. The tube fits inside the stock throttle housing and works with stock cables and known aftermarket cruise controls. It is machined from 6061 aluminum and includes self-lubricating Delrin bushings. Compatible with Kawasaki Z900RS models from 2018 through 2020, excluding Café versions.
