Top 5 125cc Dirt Bikes for Trail Riding
Next, I will explore 125cc dirt bikes for trail riding. I have personally tested all of these dirt bikes on the trail in the last few years, mainly around Texas trails.
While I maybe bias to KTMs, the KTM 125 XC is my personal favorite for the option for trail riding in the 125cc category. The simple reason is the popularity of the model as well as the stock suspension performance combined to a lightweight design, and an impressive engine. All small 2-stroke engines lack low end torque, but this KTM makes great controllable power and thanks to great gearing ratio, is easy to handle even in gnarly trails.
Here are my shortlisted top trail dirt bikes in the 125cc category:
1. KTM 125 XC
The 2024 KTM 125 XC is a powerful 125cc 2-stroke dirt bike specifically designed for enduro and trail riding. With its impressive power and agile handling, this bike easily conquers even the toughest trails.
Featuring a 124.8cc 2-stroke engine, the KTM 125 XC is peppy and responsive. The unique 2-stroke engine sound is present with a touch of low end torque. This one likes to run on the higher rev area!
This super light and nimble dirt bike with a weight of just 194lbs (88kg), the KTM 125 XC strikes the perfect balance between maneuverability and stability.
The robust gearing and stock suspension can tackle even the most gnarliest trails out there. But as most smaller engines, you will need to learn how to use the clutch well to avoid stalling and to control rear wheel spin.
Priced at $8,399, the KTM 125 XC offers great fun and excellent value for money. They are easy to find second hand and are typically well kept.
2. Yamaha YZ125X

Powered by a 124.8cc 2-stroke engine, the Beta 125 RR delivers massive performance and very responsive power. I frequently ride in a group with this dirt bike and I can tell the Beta apart by sound. The engine is very throttle responsive and likes to rev high. It also provides great low end torque for the size and is very controllable.
With a relatively low seat of 36.6″ (930mm) and weighing 207lbs (93.9kg), the Beta 125 RR is a comfortable easy to ride.
