KyVex Stem Lock | For Direct Mount Triple Clamps

Pre-Order Now, First Batch Estimated to Ship Around July 12th.

Eliminate unwanted headset play and give your front end the solid, confidence-inspiring feel it should have with the KyVex Stem Lock. 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. The result is tighter steering, improved front-end stability, and a headset that stays properly preloaded ride after ride.

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.

Precision CNC-machined from premium 6061 billet aluminum, every Stem Lock is built for maximum strength while remaining lightweight. Each kit includes three spacers to accommodate different steer tube lengths and is available in six anodized finishes to complete your build.

Why Upgrade to a KyVex Stem Lock?

A loose headset can reduce steering precision, create unwanted play, and accelerate bearing wear. The KyVex Stem Lock maintains consistent preload on the headset, helping your front end stay tight and responsive through demanding riding conditions. It's a simple upgrade that improves both handling and long-term reliability.

Ideal for:

• 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
• Performance builds where steering precision and reliability matter
