FOX Sportster RC1 Shock

FOX Technical Performance & Engineering

Key engineered features, technical highlights, and manufacturer specifications

• The FOX RC‑1 V‑twin rear shock delivers consistent damping control from start to finish, thanks to its internal floating piston that operates within an external piggy‑back reservoir.
• By isolating the shock oil from the nitrogen gas, the design prevents any mixing of fluids—a common issue with stock‑type shocks—ensuring reliable performance under varied riding conditions.

• The piggy‑back reservoir also houses dedicated compression and rebound adjusters, giving the rider precise, on‑the‑fly tuning capability.
• This dual‑adjustment layout provides the full range of control needed to fine‑tune the rear suspension for optimal handling and comfort on the track or trail.
