Perform factory-level maintenance on your 1/4 scale motorcycle with this specialized Fork and Shock Tool Set. Designed exclusively for the Losi Promoto-MX, these tools are essential for tuning your suspension setup.
The front forks and rear shock on the Promoto-MX are sophisticated, realistic components that require specific wrenches to disassemble. Using standard metal pliers or adjustable wrenches can easily scratch the delicate anodized finish of the fork caps or damage the shock collars. These molded composite tools fit perfectly, allowing you to open the forks for oil changes or adjust rear spring preload safely and easily.
Key Features
-
Non-Marring Material: Molded from high-strength composite plastic. This material is tough enough to loosen tight caps but soft enough that it will not scratch or gouge your aluminum fork tubes and shock bodies like metal tools would.
-
Fork Cap Wrench: Custom-sized to fit the large hexagonal top caps of the front fork tubes, allowing you to unscrew them to change fork oil or swap internal springs.
-
Shock Preload Spanner: Features the correct hook/tooth design to grab the threaded collar on the rear shock, making it easy to stiffen or soften the rear suspension for different track conditions.
-
Cartridge Tool: (Depending on specific mold) Often includes the internal hex or slot required to hold the inner damper cartridge during a rebuild.

Why You Need This
-
Tuning: Changing fork oil weight is the #1 way to tune the handling of the Promoto-MX. Thicker oil slows the diving during braking; thinner oil helps it soak up bumps.
You cannot access the oil without removing the caps -
Sag Adjustment: Setting the correct "Sag" (ride height) on the rear shock is critical for keeping the bike stable. This tool allows you to adjust the spring collar without removing the shock from the bike.
