⚠️ Important Vehicle Note: The scooters featured in this performance test are legally classified as motorcycles.

Viewers should consult the official manufacturer specifications and their local regulations to determine their scooter's classification and performance.
At Genuine Scooters, we love seeing our scooters in action, and nothing tells the story of performance like a dyno test. We recently put the Genuine Buddy 50 2-Stroke head-to-head against a typical QMB139 4-Stroke 50cc scooter to see which delivers better real-world performance. The results? The Buddy 50 is the clear winner.
Sustained Power: Keeping it Strong
On the dyno, the Buddy 50 recorded a highest sustained power output of 3.09 hp at 15 mph, compared to the QMB’s 2.34 hp at 18 mph — a peak-to-peak difference of over 27%. The Buddy’s power curve is flatter, which means it stays closer to peak power for longer, giving riders a more consistent and responsive ride.
Torque and Acceleration: The Buddy Pulls Ahead
Torque is what really tells the story of acceleration, and here the Buddy 50 shines. With a peak torque of 2.21 foot-pounds versus the QMB’s 1.49 foot-pounds, the Buddy shows a stunning 40% advantage. That extra torque translates directly into faster acceleration — the Buddy hits 0–30 mph in 4.7 seconds, while the QMB is 2.25 seconds slower to reach the same speed.
Top Speed & Cruising
On the dyno, the Buddy 50 around 4 mph faster than the QMB, giving riders a little extra room for cruising comfortably. While exact speed numbers can vary due to wind drag and real-world riding conditions, the Buddy consistently shows stronger performance across the board.
Why It Matters
From quicker acceleration to higher sustained power, the Buddy 50 delivers a riding experience that 4-stroke competitors can’t match. And it’s not just about the numbers — every Buddy comes with a 3-year warranty, unmatched parts support, and a variety of color options that make it as fun to own as it is to ride.
