MiKaFex Motorcycle Fork Seal Driver Kit 14PC for 35–50mm forks — stepped adapters & hardened bolt

MiKaFex 14PC Motorcycle Bike Fork Seal Driver Kit is a complete toolset that installs fork seals cleanly and evenly for 35–50mm motorcycle and bicycle front forks.

If you service forks at home or in a small shop, this 14-piece kit replaces improvised methods like PVC pipe and reduces the risk of crooked, damaged seals. The set includes six stepped adapters that cover common OEM fork diameters, plus driver plates and a hardened center bolt to press seals squarely into place. Built from reinforced materials to meet or exceed factory standards, the kit aims to speed up service, protect new seals and deliver consistent results across conventional and upside-down forks.

How does this kit make fork seal replacement easier?

The kit organizes the parts you need so you can seat seals straight and fast without trial-and-error. A dedicated driver prevents the seal lip from folding or catching, and the stepped adapters match the outer diameter of most sealing shoulders for a snug fit.

• Six adapter sizes: 35/36, 40/41, 42/43, 45/46, 47/48, 49/50 mm.
• Driver plates and hardened bolt provide even force distribution.
• Eliminates makeshift press tools and reduces rework time.

Will it work on upside-down forks as well as conventional ones?

Yes — the adapters and driver plates are compatible with both conventional and inverted fork designs. The variety of diameters covers most modern motorcycles and many bicycles with similar fork sizes, making the kit versatile for mixed fleets.

• Adapters sized to fit common upside-down and conventional fork seals.
• Flat driver plates stabilize the seal on asymmetric fork shoulders.
• Sized components minimize seal distortion during installation.

What materials and build quality can I expect?

MiKaFex constructs the kit from reinforced materials designed to withstand repeated use in a home or professional setting. Components are machined to hold tolerances so the adapters seat concentrically, reducing the chance of seal tears or uneven seating.

• Reinforced, durable adapter construction for longevity.
• Hardened central bolt for consistent pressing force.
• Manufactured to meet or exceed OEM functional standards.

How do I choose the right adapter size for my fork?

Measure the outer diameter of the fork seal seat or consult your service manual for the nominal fork tube size, then match it to the closest adapter pair in the kit. If the outer shoulder diameter falls between two sizes, pick the larger adapter for full face support to avoid pinch points.

• Measure fork seal seat diameter with calipers for best fit.
• Use the adapter that most closely matches the fork’s outer shoulder.
• When unsure, choose the larger adapter to protect the seal lip.

Who is this for? Riders and technicians who maintain their own suspension, small motorcycle shops, restoration projects and DIY mechanics will find this kit saves time and reduces installation errors. It’s especially useful if you service multiple bike models with varying fork sizes — the 35–50mm coverage handles the most common OEM diameters. MiKaFex backs the set with professional after-sales support and a one-year warranty; confirm fork dimensions and model year before ordering to ensure compatibility.
