Riding a 125cc enduro bike may seem daunting, but for many enthusiasts, it’s a compelling choice. The KTM 125 EXC is a prime example, offering a unique blend of affordability, light weight, and impressive power delivery. With a suggested retail price of $4548, this bike is nearly $1000 less than its larger counterparts, making it an attractive option for those on a budget.
The KTM 125 EXC’s engine is a marvel, providing a wide powerband and strong midrange power, while still maintaining that characteristic 125cc shriek on the top end. This is not a gutless bike; it’s a force to be reckoned with, offering a thrilling riding experience.
As we put the KTM 125 EXC through its paces, we were suitably impressed by its performance and handling. With its lightweight design and punchy engine, this bike is an ideal choice for riders of all skill levels, from beginners to seasoned veterans.
