Focus Sim Racing FSR One Twenty Sim Racing Chassis

FSR One Twenty Sim Racing Chassis

The FSR One Twenty Sim Racing Chassis is the next evolution of our original FCS-R1 — refined through engineering to deliver greater rigidity, cleaner design, and more intuitive adjustability.

Built for serious sim racers who demand precision and long-term durability, the One Twenty features updated 40×120 black anodized aluminum extrusion with a reinforced internal structure engineered to handle today’s most powerful direct drive wheelbases and high-force pedal sets with zero compromise.

This is not a cosmetic refresh. Every update was made to improve strength, usability, and overall fit and finish while maintaining the modular flexibility that made the original FCS-R1 a favorite.

What’s New on the FSR One Twenty

• Updated 40×120 aluminum profile with reinforced center core and larger internal bracing for increased torsional stiffness
• Bracket-free chassis construction using precision-drilled extrusion and integrated engineered cup washers for a cleaner, more refined appearance without sacrificing strength
• Improved wheelbase height adjustment built directly into the uprights for easy, precise positioning
• Redesigned pedal plate system with updated extrusion, clearly indexed height adjustment, and smooth front-to-back tuning using ball-bearing T-nuts and locking levers
• Optional FSR Color Accent Cup Washer Kits available in Stealth Black, Electric Blue, and Pulse Red for a more customized motorsport-inspired appearance

Wheelbase Mounting Ecosystem

The FSR One Twenty was designed around a fully modular wheelbase mounting system, allowing users to choose between universal, side mount, and front mount configurations depending on their preferred hardware and driving position.

Unlike traditional sim chassis designs that rely on generic brackets and adapters, the FSR platform uses purpose-built mounting solutions engineered specifically for rigidity, adjustability, and cleaner integration.

Primary Wheelbase Mount Options

• Universal Flat Plate – Compatible with most direct drive wheelbases including Moza, Asetek, Simagic, Logitech, Fanatec CSL/ClubSport, and more
• Side Mount Pro Modular Edition – Front plate and Fanatec-compatible side mount system designed for maximum adjustability and future modular expansion
• Side Mount Pro SIMAGIC EVO Edition – Wheelbase-specific side mount solution engineered for the Simagic EVO platform
• Focus Side Mount – Fanatec Podium Compatible – Supports Fanatec Podium wheelbases and works with optional interchangeable front mount plates
• Focus Side Mount Pro for Moza R21/R25 – Purpose-built side mount system designed specifically for larger Moza wheelbases

Optional Front Mount Plates

Several FSR side mount systems support interchangeable front mount plates, allowing users to configure the chassis for different wheelbase ecosystems without replacing the entire mounting assembly.

• Moza Front Mount Plate – Compatible with Moza R9, R12, R16, R21 Ultra, and R25 Ultra
• Simucube 3 Front Mount Plate – Designed for Simucube 3 wheelbases
• Front Mount Plate (Simucube / Simagic) – Multi-platform front mount compatibility
• Asetek Front Mount – Dedicated front mount support for Asetek wheelbases
• Universal Deck – Flat deck adapter for additional wheelbase compatibility

This modular approach allows the FSR One Twenty to evolve alongside your setup, making future wheelbase upgrades and ecosystem changes significantly easier.
