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.

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 centre 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 TF 450-RC’s overall performance and reliability.

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 optimised 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 gases are efficiently expelled, minimizing backpressure and enhancing engine performance, particularly at high RPMs.

ADVANCED ALUMINIUM CHASSIS
The TF 450-RC features a unique aluminium 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 has been 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.

The light and nimble aluminium 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.

Key design elements, including new upper and lower aluminium 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.

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 three-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.

CONFIDENCE AND CONTROL
The TF 450-RC features premium braking components for maximum control. Brembo calipers and levers provide precise, 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.

The TF 450-RC features D.I.D DirtStar rims, providing excellent impact resistance and stability in tough motocross conditions. Paired with Dunlop Geomax MX34 tyres, which offer superior traction and control, this setup ensures optimal grip and performance across various surfaces. With Progressive Cornering Block Technology (PCBT) and advanced mud evacuation, these tyres provide a consistent performance even in challenging conditions. Together, the wheels, tyres and technology deliver exceptional handling, stability, and control on any track.

EXTRA EQUIPMENT AND ACCESSORIES
