Pre-Owned 2025 Yamaha YFZ450R – 449cc High-Performance Sport ATV
The 2025 Yamaha YFZ450R is a race-ready high-performance sport ATV engineered for motocross, dune riding, and aggressive off-road competition. Powered by a 449cc liquid-cooled DOHC four-stroke single-cylinder engine with five titanium valves, it delivers exceptional throttle response, explosive acceleration, and championship-level performance. Yamaha's advanced Fuel Injection (YFI) system with a 42mm throttle body ensures precise fuel delivery and consistent power across the entire RPM range.
The engine is paired with a 5-speed manual transmission featuring an assist-and-slipper clutch, providing lighter clutch effort, smoother shifting, and improved stability during aggressive downshifts. An O-ring chain final drive efficiently transfers power to the rear wheels, making the YFZ450R ideal for competitive racing and high-speed trail riding.
Built around a lightweight hybrid aluminum and steel chassis, the YFZ450R delivers exceptional rigidity, precise handling, and excellent mass centralization. The ATV is equipped with fully adjustable long-travel independent double wishbone front suspension featuring Kashima®-coated piggyback shocks, along with a fully adjustable rear piggyback shock mounted to a cast aluminum swingarm. This premium suspension system provides outstanding control, stability, and rider confidence over jumps, whoops, and rough terrain.
