Yamaha YFZ 450 In-Depth Guide
A stock YFZ 450 ATV has a top speed of approximately 75MPH (see top speeds list).
Because 2-stroke engines are designed to run at a higher RPM, they also tend to wear out faster; a 4-stroke engine is generally more durable. That being said, 2-stroke engines are more powerful.
A two-stroke engine can theoretically produce twice the amount of power because it fires once every revolution, whereas four-strokes fire once every other revolution. Because of this, it has a higher power-to-weight ratio, making it more desirable for many riders.
A 2-stroke engine requires only one complete crankshaft revolution to complete the four stages of combustion. A 4-stroke engine requires two crankshaft revolutions. This advantage explains why a 250-cc 2-stroke engine makes more power than a 4-stroke of the same size.
In addition to offering the longest power delivery on the track, the 450 SX-F also spins the most peak horsepower and torque in the class with 55.0 hp at 9,400 rpm and 34.3 pound-feet of torque at 7,500 rpm, as measured on our in-house Dynojet 250i rear-wheel dynamometer.
