The KTM 125 EXC Enduro: a bike that defies its diminutive displacement with a potent blend of power and agility. Weighing in 20 pounds lighter than its larger siblings, the 125 EXC is a game-changer for riders of all skill levels, particularly those seeking a lightweight, fuel-efficient, and cost-effective option.
Its 125cc engine may not seem like much, but KTM has crafted a masterpiece that produces a wide powerband, strong midrange punch, and a characteristic 125cc shriek on the top end. Gone are the days of gutless 125s; this bike packs a surprising amount of punch, making it an ideal choice for riders who want a bike that’s both manageable and exciting.
As we put the 125 EXC through its paces, we were impressed by its ease of handling, its ability to carve through tight trails with precision, and its impressive fuel economy. With a suggested retail price of $4548, this bike offers an unbeatable combination of performance, value, and fun.
