Built to Dominate – Engineered to Win

The All-New 2025 Triumph TF 450-RC Edition: introducing an all-new 450cc competition engine, and the strongest power-to-weight ratio in its class. Developed in close collaboration with motocross legend Ricky Carmichael, it features RC’s handpicked specs and signature components, built to deliver relentless performance and ultimate control.

Podium Performance

All-new, Triumph’s first 450cc competition powertrain is compact, mass-optimized and built to take the holeshot. Engineering, design, and equipment working in harmony for class-leading power, control, and flexibility. The TF 450-RC is ready to compete at the highest level.

Power Delivery

Lightweight 4-Stroke Powertrain – The single-cylinder, SOHC 450cc engine of the TF 450-RC is built for racing, delivering robust power while minimizing weight for a class-leading power-to-weight ratio.  At the core of this engine are top-tier components, including a Konig-forged aluminum piston, which provides strength and durability at high speeds, and Del West titanium valves for improved airflow and faster actuation. With class-leading power, the 450 engine offers relentless drive and acceleration, making it a standout in the motocross segment. The TF 450-RC’s 5-speed gearbox, with a quickshifter fitted as standard for clutchless upshifts from 2nd to 5th gear, ensures seamless power delivery for maximum focus on the track. A balance of power, precision, and durability that sets a new standard in the 450cc motocross class

Airflow

The 450cc engine's combustion chamber is fully machined for optimal airflow and efficiency. The 3-axis machined combustion chamber and ports ensure precise geometry for peak performance, while diamond-like carbon (DLC) coated rockers reduce friction, improving the engine's efficiency and longevity. The TF 450-RC’s 450 airbox and intake system ensures that the engine gets a consistent, high volume of air, which is critical for performance and efficiency. The intake system is paired with a TwinAir air filter, known for its durability and filtration efficiency. The tool-free filter access makes it easy to maintain the bike in rugged conditions, ensuring optimal airflow at all times.

Engine Management

The TF 450-RC is equipped with a cutting-edge engine management and intake/exhaust system, designed to deliver exceptional performance and control. At its core, the bike features a Dellorto throttle body integrated with an Athena engine management system, ensuring precise fuel delivery and throttle response. This system allows riders to fine-tune parameters like traction control and launch control via the MX Tune Pro smartphone app, offering adaptable performance for varying track conditions. The TF 450-RC features a unique engine map customized by Ricky Carmichael to deliver the exact power and control he demands.

Exhaust System

The exhaust system of the TF 450-RC is designed to complement its high-performance engine. The standard model features a lightweight stainless-steel exhaust with an integrated resonator to improve cylinder evacuation, and hydroformed components for optimized routing and high gas flow. For riders looking for an even higher level of performance, an Akrapovic titanium exhaust is available as an accessory, with a dedicated engine map to optimize the engine's output. This system ensures that exhaust gases are efficiently expelled, minimizing backpressure and enhancing engine performance, particularly at high RPMs.

Designed for The Win

The 450cc engine’s narrow profile improves ergonomics, allowing riders more control and comfort. It is housed in light magnesium covers for further weight reduction. The high-capacity clutch features a steel basket, and plates designed to handle the demands of racing, ensuring durability during intense use. The hydraulic clutch actuation, with Brembo master and slave cylinders, ensures smooth and consistent clutch control.

Lightweight and Strong

The TF 450-RC features a unique aluminum chassis, designed to provide a perfect balance of performance, mass and flexibility. The frame’s spine and twin cradle design offer exceptional strength while minimizing weight, contributing to the bike’s overall agility and handling on the track. Hand TIG-welded craftsmanship ensures durability and precision in every detail. The chassis was race-optimized for longitudinal, lateral, and torsional stiffness, ensuring the best performance under extreme conditions. This allows for exceptional handling and provides the rider with precise feedback and control during intense riding. The result is a chassis that delivers top-tier performance and reliability, tailored for competitive racing.

Lightweight Power Advantage

The light and nimble aluminum chassis of the TF 450-RC plays a crucial role in achieving its class-leading power-to-weight ratio. By minimizing the overall weight of the bike, the chassis allows the powerful 450cc engine to deliver exceptional acceleration and performance. This combination of a high-performance engine and a lightweight frame gives riders unmatched agility, control, and speed, making the TF 450-RC a top contender in its class.

Control and Balance

The aluminum chassis is specifically tuned for the 450cc powertrain, delivering outstanding control and balance. Key design elements, including new upper and lower aluminum triple clamps, and dedicated top-end mounts, are engineered to handle the increased power and loads. This optimized stiffness provides superior stability and responsiveness, giving riders the confidence to push the bike to its limits.

Suspension

The KYB AOS coil suspension on the TF 450-RC is designed for superior shock absorption and handling. Featuring an Air/Oil Separation (AOS) system, this suspension ensures smoother, more consistent damping by preventing oil aeration, which results in more precise control and stability across various terrains. Paired with this is the 3-way piggyback shock, which allows for fine-tuning of compression, rebound, and preload settings. This ensures that the suspension can be fully customized to the rider’s preferences and track conditions, providing enhanced handling, traction, and comfort, especially during high-speed and demanding motocross events. Together, these components deliver exceptional ride quality and control.

Precision Braking

The TF 450-RC features premium braking components for maximum control. Brembo calipers and levers provide precise and responsive braking, while Galfer discs offer durability and excellent heat dissipation. This combination ensures smooth, reliable braking performance, even under heavy use, giving riders confidence and control in all racing conditions.

Durable Wheel Set Up

The TF 450-RC features D.I.D Dirt Star rims, providing excellent impact resistance and stability in tough motocross conditions. Paired with Dunlop Geomax MX34 tires, which offer superior traction and control, this setup ensures optimal grip and performance across various surfaces. Together, the wheels and tires deliver exceptional handling, stability, and control on any track.
