Introducing the 2024 Beta RX 4T 450, a powerful contender in the cross-motocross segment that promises to elevate the riding experience for both competitive racers and trail enthusiasts alike. Known for its commitment to quality and performance, Beta has crafted the RX 4T 450 to dominate a wide range of terrains, from rugged trails to motocross tracks. With its cutting-edge technology and robust build, this motorcycle is designed to deliver an exhilarating ride that pushes the boundaries of performance and agility. At the heart of the Beta RX 4T 450 lies a formidable engine, featuring titanium valves and a high compression ratio of 13.5:1 that ensures robust power delivery. The 450cc four-stroke engine utilizes a sophisticated Elldor electronic fuel injection system, optimizing performance for any riding condition. With a bore and stroke of 97.0 mm by 60.8 mm, this machine delivers an impressive balance of torque and horsepower, making it an agile beast on the track. The 5-speed gearbox allows for smooth gear transitions, while the liquid cooling system ensures optimal engine temperatures, enabling riders to push their limits without overheating. With a weight of just 104.5 kg (230.4 pounds), the RX 4T 450 is lightweight yet sturdy, providing an unparalleled riding experience that combines speed with control. The RX 4T 450 is equipped with advanced features that enhance its performance and rider comfort. The Molybdenum steel frame is meticulously designed with a double cradle split above the exhaust port, offering exceptional strength and stability while minimizing weight. The hydraulic USD close cartridge fork (48mm) and monoshock rear suspension with a progressive compound lever work in tandem to absorb bumps and provide precise handling across various terrains. Safety is paramount, and the braking system reflects this, featuring a 255 mm front disc with a double-piston floating caliper and a 240 mm rear disc with a single-piston caliper, ensuring powerful stopping power when it’s needed most. The electric starter adds convenience, while the adjustable seat height of 945 mm (37.2 inches) allows riders to tailor their comfort level. **
