The 2025 Yamaha YFZ450R SE is a high-performance sport ATV built for track and aggressive off-road use. It’s powered by a liquid-cooled 449 cc single-cylinder engine with a DOHC five-titanium-valve head and Yamaha Fuel Injection through a 42 mm throttle body for strong pickup from idle through the top end. Transmission is a 5-speed manual with an assist & slipper clutch.
The chassis is a hybrid aluminum/steel frame allowing the engine to sit low for centralized mass, paired with motocross-style suspension: independent double-wishbone front with 9.8″ of travel, and cast-aluminum swingarm rear with 11.0″ travel, both fully adjustable.
