The NCY Star Racing Clutch Bell is a PTFE-coated, vented performance clutch bell for 125cc–170cc GY6 engines and the Honda Navi 110. The black PTFE exterior coating dissipates heat faster than raw steel, while the sandblasted internal friction surface provides immediate, aggressive clutch shoe engagement. The star-cut venting acts as a centrifugal fan to pull cool air through the assembly and shed clutch dust. At 660g, it reduces rotational mass for faster RPM response compared to stock bells.
