The All Balls Fork Seal Kit (45-57-11) is a premium aftermarket front fork seal replacement kit for motocross, enduro, and off-road motorcycles. Fitting fork assemblies with a 45mm inner diameter, 57mm outer diameter, and 11mm seal height, this kit is a common specification across a wide range of Honda CR and Suzuki RM models.
How does it outperform OEM seals?
The kit features an advanced triple-lip seal design that balances internal fork pressure, reduces friction, minimises component wear, and lowers operating temperature — all of which extend seal life and deliver more consistent fork performance.
Most notably, it reduces stiction (the initial resistance before your fork begins to move) to approximately one-half to two-thirds of standard OEM levels. Less stiction means your suspension responds faster and more accurately to terrain, improving handling and rider confidence across all conditions.
Key Specifications
- Seal dimensions: 45mm inner / 57mm outer / 11mm height
- Triple-lip seal design for pressure balance and reduced friction
- Stiction reduced to approximately one-half to two-thirds of OEM levels
- High-quality elastomer construction for durability in off-road conditions
Installation Tip
Replace your dust seals (fork wipers) at the same time as the fork oil seals. Worn wipers allow dirt and debris to reach the new seals, dramatically shortening their service life. Replacing both together ensures maximum protection and performance.
When should you replace your fork seals?
Replace when you notice oil leaking down the fork legs, reduced or inconsistent damping, visible seal damage, dirt entering the fork internals, or a harsh and unresponsive fork feel.
