Indexed Chain Adjuster Kit – Stark Varg MX / EX / SM (2024+)

The Indexed Chain Adjuster Kit for the Stark Varg MX / EX / SM (2024+) delivers precise and repeatable chain alignment for riders who demand professional-grade accuracy.
CNC-machined from 7075-T651 aerospace aluminium (Ergal), it provides exceptional rigidity, low weight, and long-term durability under MX, Enduro, and Supermoto conditions.

Developed in-house at AXIIS as the first indexed chain adjuster engineered specifically for the Stark Varg platform, ensuring perfect fitment and optimal mechanical performance.

A hardened ball-detent mechanism produces five defined clicks per full rotation, each equal to 0.25 mm of adjustment. These micro-increments ensure exact, symmetrical chain tensioning with no guesswork and no drift.

Unlike standard adjusters that allow the wheel to slip backward while tightening the axle nut, this system features a self-holding wheel position. It holds the axle exactly where you set it, so there’s no need to push the wheel forward by hand. The wheel remains locked in its adjusted position throughout the tightening process, making chain setup faster, easier, and far more consistent.

The adjustment knob is designed for practicality and speed, featuring a hand-operable profile with a precision-engraved AXIIS “A” logo, and can also be turned using a standard 18 mm socket.
Each side includes M10 threaded mounts for swingarm sliders or paddock-stand spools, while a clear alignment scale offers rapid visual reference for matching both sides.

This is a premium upgrade engineered for riders who demand maximum precision, convenience, and durability.
