ALL NEW TF 450-RC EDITION

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-RCs 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.

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.

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.

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.

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.
