Why This Tool is Essential

Valve adjustments with standard wrenches are frustrating—the lock nut often shifts your carefully set clearance when you tighten it. The Motion Pro tappet adjuster solves this problem by holding the lock nut stationary while you make micro-adjustments to the valve screw, then keeps everything locked in position as you torque the nut. The result is accurate, repeatable valve clearances every time.

Fitment & Applications

Designed for motorcycles with 9mm valve adjustment lock nuts, including Honda Grom (all generations), Monkey 125, and many other Honda, Kawasaki, and Suzuki models. Essential for routine valve service, engine rebuilds, and performance builds requiring precise valve timing.

Professional Results at Home

This tool brings dealership-level precision to your home garage, making valve adjustments faster, easier, and more accurate. A must-have for any serious motorcycle enthusiast performing their own maintenance.
