The Yamaha YFZ450R SE is an agile ATV especially developed for racing. It features sharp handling, a tight suspension and a high-tech engine, all working together to reward its rider with the purest riding experience on four wheels.
At the heart of the YZF450R SE lies a 442cc, 32-bit fuel injected engine, mated on a 5 speed gearbox with manual clutch. The ride is kept in check by a long-travel suspension, which lets the tyres maintain longer and more consistent ground contact. Up front, the ATV received independent front suspension, so the movement of each front wheel is not affected by the other. The rear axle is supervised by a cast aluminium swingarm, threaded preload adjustable coil-over springs and a 3-way adjustable damper.
The ergonomy department is also pretty good represented, the YFZ450R featuring a comfortable seat, adjustable handlebars and a set of convenient side panels which provide a comfortable grip for knees.

About Yamaha YFZ450R SE
The YFZ450R is the number one choice of racers. And one look at the specification tells you why. The culmination of a decade of race-winning experience, it’s a total package of sharp-handling, tight suspension and a high-tech engine.
Agile and nimble, competitive performance is what it’s all about. The fast-spinning, 5-valve DOHC 449cc engine is held low in the rigid, lightweight hybrid chassis, while long-travel suspension and a wide track contribute to the overall balance.
The 32-bit fuel injected engine, gearbox, clutch and exhaust deliver the perfect combination of hole-shot acceleration and smooth power - right through the rev range.
We know that racing isn’t about compromise. It’s about being the best. And that’s an attitude reflected in the design of every Yamaha Sports ATV.
Discover tough, lightweight frames that move with you, while withstanding every knock and bump. Experience ergonomic designs that keep your body comfortable, and your mind on what lies ahead.
At the heart of every Yamaha Sport ATV is an engine perfected by intensive research and development. We are as committed to engineering excellence as you are to winning the next race. Offering everything from big-torque, 4-stroke power to exciting acceleration, these are ATVs to leave the competition standing.
Precision engine design
The 4-stroke engines used in Yamaha ATVs are designed to give you high levels of torque at low and mid-range rpm The result is increased traction - on all kinds of terrain.
Electronic Fuel Injection
The YFZ450R employs fuel injection for precise fuel delivery. With a 42mm Mikuni® throttle body and 12-hole injector, this system provides exceptional atomisation of the fuel for maximum power. The system also includes ISC (Idle Speed Control) for easy, reliable start-up and warming.
Hybrid chassis engineering
Yamaha Sports ATVs use both steel and aluminium in their chassis. These ’Hybrid chassis’ frames and swing arms combine maximum strength with class-leading low weight.
The YFZ450R has a 5-speed gearbox. Selecting gears using the proven and familiar foot lever/hand clutch system lets you smoothly shift between ratios. The throttle lever requires low effort and is comfortable to use.
Long travel adjustable suspension
With long-travel suspension, tyres maintain longer and more consistent ground contact - even on uneven terrain. With independent front suspension, the movement of each front wheel is not affected by the other. This improves handling by allowing the ATV to track bumpy terrain more accurately and remain in a level, controlled posture.
The YFZ450R works in perfect harmony with a rider. While the design offers maximum room to move around and hang off in corners, side panels provide a comfortable grip for knees. 4-position adjustable handlebars accommodate different body sizes, ride styles and circumstances.
