Moto-House MX Fork Seals 47.50mm 16-1071 — Yamaha YZ125 / YZ250 / YZ250F / YZ450F / WR 2004-2022

Product Description

Restore plush, predictable front suspension travel and protect your brake rotors from oil contamination with Moto-House MX Fork Seals. Blown factory oil seals allow critical damping fluid to escape down your lower fork legs, resulting in a harsh, under-damped ride and dangerous oil buildup on your front braking system. This premium 47.50 mm replacement pair re-establishes a dynamic hydraulic seal inside your front forks, ensuring consistent compression and rebound performance on rough tracks or technical trails.

Manufactured from top-tier, high-performance elastomer compounds, these oil seals are engineered to minimize stiction while maximizing durability. The precise internal lip profile stands up to high fluid pressures, aggressive roost, and fine silt. Designed to exact factory dimensions ($47.5\text{ mm} \times 58\text{ mm} \times 8.5\text{ mm}$), K&S Technologies provides a reliable fitment match that keeps your fork oil firmly locked where it belongs, giving you maximum confidence under heavy braking and hard landings.

Frequently Asked Questions

Q: Does this package include both the oil seals and the outer dust wipers?
A: This specific kit contains a pair of high-quality fork oil seals. If your outer dust seals are torn or cracked, we recommend purchasing fresh dust wipers separately to prevent dirt from reaching your new oil seals.

Q: What size are these fork seals?
A: These seals measure exactly 47.50 mm inner diameter, 58.00 mm outer diameter, and 8.50 mm thickness, making them a direct fit for the listed Yamaha KYB fork applications.

Q: Should I change the seals on both fork legs even if only one side is leaking?
A: Yes, always replace fork seals as a complete set. If one side has failed due to wear or age, the other side has experienced the same operating hours and will typically fail shortly after.

Expert Pro-Tip: When sliding your new fork seals over the sharp edges of the inner fork tube, always wrap a layer of electrical tape or a thin plastic bag over the top of the tube and the oil lock piece grooves. Coat the tape liberally with fresh fork oil before sliding the seal down. This keeps the razor-sharp metal edge of the bushings and snap-ring grooves from slicing the delicate inner sealing lip of your new seal during assembly.
