Steering Stem Bearing Kits for: Gas Gas, Husqvarna, KTM | SSK-T-070

Factory Links OEM Series® steering stem bearing kits are designed to restore smooth steering performance and long-term durability to your motorcycle’s front end.
Each kit includes high-quality tapered roller bearings and premium dust seals engineered specifically for off-road motorcycles. Manufactured to strict OEM tolerances, these components provide precise steering feel and reliable performance in harsh riding conditions.
Factory Links kits deliver OEM-quality performance at an excellent value compared to costly dealer replacements. For riders seeking maximum performance in professional racing environments, Factory Links also offers Race Series® components developed for the most demanding applications.

Information
Our steering stem bearing kits include all the components required for a complete rebuild of your motorcycle’s steering head assembly.

Designed specifically for off-road motorcycles, these kits restore precise steering response while protecting critical components from contamination caused by mud, water, and debris.
Factory Links components are manufactured to strict OEM tolerances to ensure proper fit, long service life, and consistent performance under demanding riding conditions.
Technical Details
TAPERED BEARINGS

Factory Links tapered roller bearings are manufactured with precisely matched cone angles between the inner race, outer race, and rollers. These geometries are designed so their geometric axes intersect at a single point on the bearing centerline.
This alignment allows the rollers to roll rather than slide, ensuring true rolling contact, reduced friction, and uniform load distribution. Maintaining this precise geometry is critical — even small deviations can cause sliding, heat buildup, and premature bearing wear.
BEARING RACES
Precision-ground bearing races are included in each kit to ensure proper seating and alignment of the tapered bearings during installation. Manufactured from hardened steel and produced to strict dimensional tolerances, these races help maintain smooth steering operation and extend bearing service life.
DUST SEALS
Dust seals are manufactured from high-quality Nitrile Butadiene Rubber (NBR) and molded to precise OEM specifications. These seals protect the steering head assembly by preventing abrasive particles, water, and contaminants from entering the bearings, helping to maintain smooth steering operation and extend component life.
KIT INCLUDES
- Precision tapered roller bearings designed for smooth steering operation and high load capacity
- Hardened and precision-machined bearing races for proper seating and long service life
- High-quality NBR dust seals to protect against mud, water, and contaminants
All components are manufactured to strict OEM tolerances to ensure proper fit, durability, and reliable steering performance.
