The Aprilia 125 Pegaso – a bike that defies convention and shatters preconceptions about its class.
In reality, bikes like the Pegaso are not suited for learners, who would be better off on more forgiving machines such as the Yamaha XT600. The Aprilia’s highly-tuned engine requires aggressive clutch slip to unlock its full potential, making it a challenging mount even for experienced riders.
But for those willing to tame its ferocity, the Pegaso rewards with outstanding balance, turn-in and stability. Its inverted front suspension is a marvel, providing precise handling and a planted feel that belies its relatively low weight.
The engine’s powervalve system brings a characteristic chug-chug-chug to 6,000 rpm before delivering a sudden, explosive kick into the high rev range – an experience both exhilarating and intimidating in equal measure. With its unique blend of power and handling, the Aprilia 125 Pegaso is a bike that demands respect, but yields immense rewards for those brave enough to ride it with finesse.
