🔧 Key Technical Features

• 🟣 Frame-Hugging Lower Lip Design
  Outer seal lip extends over the frame cup to block direct entry of water, mud, and debris — a major upgrade over flat OEM gaskets.
• 🟤 Precision-Fit Upper Bore Seal
  Stack-on top seal is engineered with high interference fit to seat firmly in the steering head bore — zero wobble, zero migration.
• ⚙️ Enhanced Stack-On Architecture
  Designed to match OEM assembly method for Honda CRF frames, ensuring perfect fit and compatibility without press tools.
• 🔩 Dual Contact Seal Geometry
  Angular contact lips dynamically adapt to steering movement and bearing preload, maintaining a tight seal under pressure and flex.
• 💨 Grease-Retaining & Dust-Blocking
  Forms a complete enclosure with the bearing to preserve grease, reduce contamination, and extend service intervals.
• 🏁 Race-Tested Design
  Proven in real-world off-road and MX conditions for durability and performance under pressure washing and extreme terrain.
