The All Balls Dust Seal Kit is a precision-engineered front fork dust seal replacement kit designed for motocross and off-road motorcycles. This kit fits fork assemblies measuring 45mm inner diameter by 57mm outer diameter, making it compatible with a range of popular Honda CR and Suzuki RM models.
Dust seals — also known as fork wipers — are the first line of defence in your fork assembly. They prevent dirt, mud, water, and debris from reaching the oil seals beneath, protecting your fork internals from premature wear and costly damage.
What bikes does this kit fit?
This dust seal kit is compatible with the following models using a 45×57mm fork seal specification:
- Honda CR125
- Honda CR250
- Honda CR500
- Suzuki RM125
- Suzuki RM250
Always confirm your fork inner and outer diameter measurements before purchasing to ensure correct fitment.
Key Features and Benefits
Constructed from a durable elastomer rubber compound, these dust seals are built to withstand the abrasive conditions of off-road and motocross riding. The flexible material resists hardening, cracking, and tearing even under heavy use and exposure to mud, grit, and trail debris.
Each seal is engineered to slide smoothly over the inner fork tube, minimising drag on the fork action while maintaining a reliable wiper contact. The kit is sold as a pair — one seal per fork leg — ensuring both sides of your front suspension are protected equally.
When should you replace your fork dust seals?
You should replace your fork dust seals when you notice any of the following:
- Visible nicks, cuts, or tears in the seal lip
- The seal has hardened or lost flexibility
- Dirt or debris is entering the fork internals
- Oil is leaking past the main fork seals
- Reduced fork performance or sticking action
Regular inspection and timely replacement of dust seals can extend the life of your fork oil seals significantly, reducing overall maintenance costs.
