Nearly a year has passed since Triumph rolled out the TF 250-X, their ambitious foray into the motocross arena and a project in the making for over three years now. But the Hinckley brand is just getting started unloading their arsenal of planned off-road machines and today they have unveiled their first 450cc motocross bike called the TF 450-RC Edition.

Designed in collaboration with Ricky Carmichael, the TF 450-RC boasts the GOAT’s chosen specification and signature graphics. Moreover, Triumph states the new machine also earns bragging rights for the strongest power-to-weight ratio in its class in part due to a compact and mass-optimized SOHC 450cc powerplant. 

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 DelWest titanium valves for improved airflow and faster actuation. The TF 450-RC’s 5-speed gearbox boasts a quickshifter fitted as standard for clutchless upshifts from 2nd to 5th gear.

The 450cc engine’s combustion chamber is fully machined for optimal airflow and efficiency while the 3-axis machined combustion chamber and ports are designed with precise geometry for peak performance. Diamond-like carbon (DLC) coated rockers reduce friction, improving the engine’s efficiency and longevity.

The airbox and intake system ensures that the engine gets a consistent, high volume of air, which is critical for performance. The system is paired with an air filter by TwinAir, 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.

The TF 450-RC is equipped with cutting-edge engine management and an 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.

For increased versatility, the TF 450-RC features selectable engine maps, including a unique map customized by Ricky Carmichael to deliver the exact power and control he demands.

With its narrow profile, the 450cc engine has improved ergonomics that allow 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. Moreover, the hydraulic clutch actuation, with Brembo master and slave cylinders help deliver smooth and consistent clutch control.

Precision, control, and durability are at the forefront of the TF 450-RC’s design, especially with the inclusion of the ODI RC4 Signature handlebars. Made from triple-butted, tapered wall tubing, these bars are designed to deliver a perfect balance of strength and flex. Constructed from seamless 2014-T6 alloy and hard-anodized for enhanced durability, the bars feature oversized clamps and half-waffle ODI lock-on grips, ensuring excellent rider comfort, vibration dampening, and impact resistance.

The top engine mounts on the TF 450-RC were hand-picked by Ricky to enhance handling, especially under heavy front-end loads. This setup ensures the bike maintains optimal control and stability during even the most demanding rides.

The XTrig Holeshot Device gives riders the perfect start by preloading the front suspension, lowering the center of gravity and reducing front wheel lift for quicker acceleration. The bike is also equipped as standard with a Triumph Racing Hinson clutch cover, a front disc guard to deflect debris and impacts, and a gripper seat cover to reduce slipping and enhance rider control. These premium components elevate the overall performance and reliability of the TF 450-RC.

Advanced Aluminum Chassis

The TF 450-RC features a unique aluminum chassis, designed to provide optimal 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. For durability and precision, the new bike boasts hand TIG-welded craftsmanship.

The chassis has been race-optimized for longitudinal, lateral, and torsional stiffness in order to deliver great performance under extreme conditions. This allows for optimal 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.

The light and nimble aluminum chassis of the TF 450-RC plays a crucial role in achieving its class-leading power-to-weight ratio. This combination of a high-performance engine and a lightweight frame gives riders greater agility, control and speed

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, providing excellent stability and responsiveness.

The KYB AOS coil suspension on the TF 450-RC features an Air-Oil Separation (AOS) system, which delivers more consistent damping by preventing oil aeration. Paired with this is the three-way piggyback shock, which allows for fine-tuning of compression, rebound, and preload settings. 

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 Akrapovič titanium exhaust is available as an accessory, with a dedicated engine map to optimize the engine’s output. This system ensures that exhaust gasses are efficiently expelled, minimizing back pressure and enhancing engine performance, particularly at high RPMs.

Brakes & Wheels

The TF 450-RC features Brembo calipers and levers while Galfer discs offer durability and excellent heat dissipation. This combination is designed to deliver smooth, reliable braking performance, even under heavy use.

The TF 450-RC features D.I.D DirtStar rims paired with Dunlop Geomax MX34. With Progressive Cornering Block Technology (PCBT) and advanced mud evacuation, these tires provide consistent performance even in challenging conditions. 

Extra Equipment

A network of Triumph Off-Road dealers and a 24/7 parts supply web tool provide quick access to servicing and parts, keeping riders on the track with minimal interruptions.

Riders can also use the 24/7 parts supply web tool to browse specialist equipment and accessories for their TF 450-RC edition, ranging from an Akrapovič titanium exhaust with dedicated engine map, WiFi module kit, air filter covers, a Gripper seat, and more. 

Colors, Availability and Pricing

The color design prominently incorporates Triumph Performance Yellow with black and white accents. It also includes RC’s iconic number 4, GOAT logo, and key sponsor details, adding a personalized flair that reflects the spirit of this motocross legend. This design is carried across number boards, swingarm decals, and other visual elements.

The new TF 450-RC will be available from $10,995 USD and $13,295 CAD. Customers can find out more at triumphmotorcycles.com. Bikes will be arriving atto Triumph Off-Road dealerships beginning February 2025.
