The KTM 125 EXC Enduro: a diminutive dynamo that’s been turning the world of off-road riding on its head. With a claimed dry weight of just 97kg, this tiny two-stroke is a marvel of agility and responsiveness, making it a joy to flick and weave through tight trails.
In our testing, we were amazed to find that the 125 EXC was capable of blistering lap times, with a best of 3:55 achieved by our colleague Evan – a time that would put many larger and more powerful bikes to shame. But it’s not just about speed: the 125’s engine character is a perfect blend of mid-range punch and top-end rush, making it a thrill to ride on a variety of terrain.
Whether you’re carving up technical sections or blasting down smooth fire roads, the KTM 125 EXC Enduro is an absolute riot to ride – and one that will leave you grinning from ear to ear, every time.
