Yamaha YZ 125

The 2019 Yamaha YZ125 represents a continuation of Yamaha's long and storied legacy in the two-stroke motocross segment. For decades, the YZ125 has been a benchmark for lightweight, agile dirt bikes, and the 2019 model upheld this tradition. It remained a highly competitive option for aspiring racers and weekend warriors alike, directly challenging rivals such as the KTM 125 SX and Husqvarna TC 125, which also feature potent 125cc two-stroke engines. While the motocross landscape has seen significant four-stroke dominance, the YZ125 continued to offer a compelling alternative for those who appreciate the unique characteristics of a two-stroke.

At its heart, the 2019 Yamaha YZ125 is powered by a 125.0 ccm (7.63 cubic inches) single-cylinder, two-stroke engine. This highly tuned powerplant is rated to produce 33.5 HP (24.5 kW), providing a lively and responsive power delivery that is characteristic of 125cc two-strokes. Despite its relatively small displacement, the YZ125 is capable of reaching a top speed of 96.0 km/h (59.7 mph), showcasing its competitive performance on the track. Fuel capacity stands at 8.00 litres (2.11 US gallons), offering a decent range for extended practice sessions or race motos before needing to refuel. The bike's powerband requires a rider to keep the engine revving, rewarding precise throttle control and clutch work.

Riding the YZ125 is defined by its nimble handling and responsive feel. The bike's lightweight chassis, combined with its compact engine, contributes to its exceptional agility on the track. The seat height, at 975 mm (38.4 inches) at its lowest setting, is typical for a motocross machine, designed to provide ample ground clearance and an aggressive riding posture. The YZ125’s suspension components are generally well-regarded for their ability to soak up bumps and provide stable handling over varied terrain, allowing riders to maintain control through whoops and jumps. Its narrow ergonomics facilitate easy body movement, crucial for navigating tight turns and maintaining momentum.

The 2019 Yamaha YZ125 is primarily aimed at intermediate to expert riders, as well as ambitious younger racers making the step up from smaller displacement machines. Its two-stroke nature demands a more engaged and skilled rider to extract its full potential, making it an excellent platform for developing fundamental motocross techniques. While it can be ridden by beginners, its aggressive power delivery might be challenging for those completely new to dirt riding. Ultimately, the YZ125 remains a highly respected and capable motocross bike, offering a pure, unadulterated riding experience that continues to resonate with a dedicated fan base.
