🏁🔥 2026 Yamaha YFZ450R SE
Race-proven performance meets Special Edition attitude. The 2026 Yamaha YFZ450R SE takes Yamaha’s championship-winning Sport ATV platform and turns up the style with exclusive SE graphics and Yamaha Genuine Accessories. Underneath the aggressive appearance is a serious competition-focused machine featuring a quick-revving 449cc engine, professional-caliber aluminum/steel chassis, fully adjustable KYB suspension, and race-ready ergonomics.

At its heart is a 449cc liquid-cooled DOHC four-stroke engine with five titanium valves, engineered for strong midrange and top-end performance. Yamaha Fuel Injection uses a 42mm Mikuni throttle body and 12-hole injector for precise fueling, while the 5-speed transmission and assist-and-slipper clutch help deliver smooth, controlled power when you're attacking the track.
