Bel-Ray High Performance Fork Oil

Anti-Friction and Stiction Reduction

One of the biggest hurdles to smooth suspension is “stiction”—the friction that prevents the fork from moving easily at the start of its stroke. Bel-Ray incorporates friction modifiers that coat internal sliders and bushings, allowing the fork to move with minimal resistance. This results in better small-bump compliance and a ride that feels “plush” rather than harsh.

Consistent Damping in All Conditions

As you ride, the friction inside your forks generates heat, which can cause thin, low-quality oils to lose their viscosity and “fade.” Bel-Ray uses high-viscosity index (HVI) base stocks that remain stable regardless of temperature. This means your damping remains consistent from the first mile of a cold morning to the end of a long, hot afternoon in the saddle.

Advanced Seal and Component Protection

This fork oil is enriched with a robust additive package designed to preserve the life of your suspension hardware:

• Anti-Foam Chemistry: Prevents air entrainment, ensuring the valves always move through liquid, not air bubbles, for reliable damping.
• Seal Conditioners: Keeps rubber fork seals soft and pliable, significantly reducing the risk of leaks and extending service intervals.
• Anti-Wear Agents: Protects internal aluminum and steel parts from scoring and corrosion.

Choose Your Weight: 5W, 7W, 10W, 15W, 20W, 30W

Bel-Ray offers a wide range of viscosities, allowing you to customize your damping curve:

• 5W / 7W: Ideal for lightweight riders or those seeking a very soft, fast-reacting front end.
• 10W: The standard “medium” weight, perfect for general street use and factory replacements.
• 15W / 20W: Heavy-duty weights that provide more “slow” damping; great for heavy touring bikes or riders wanting to reduce front-end dive during braking.
• 30W: Used primarily in vintage dampening-rod forks or specialized heavy-duty applications.
