. Designed for performance-focused e-moto riders, this upgrade replaces the factory headset bolt with a full-length threaded system that applies constant compression between the upper and lower triple clamps.

By locking the upper and lower triple clamps together into one rigid assembly, the KyVex Stem Lock helps prevent the stem from loosening over time. You'll immediately notice a more precise steering feel with reduced flex and unwanted movement, whether you're charging through rough trails, landing jumps, or carving corners.

It's a simple upgrade that improves both handling and long-term reliability.

Trail and enduro riders looking for a tighter, more responsive front end

Motocross riders who regularly subject their bike to hard landings and rough terrain
