6 Best 125cc Dirt Bike in 2026
The 125cc Dirt Bike Class
A 125cc dirt bike is the ideal size for teenagers, smaller adults, and beginner riders who want real off-road capability without overwhelming power. These bikes are light enough to pick up after a fall, forgiving enough to learn on, and still fast enough to be genuinely fun on trails and small tracks. The 125cc class has seen strong competition in recent years from both established brands and budget manufacturers, giving buyers more choices than ever at every price point.
Here are the six best 125cc dirt bikes for 2026.
Top Picks Compared
| Bike | Engine Type | Transmission | Weight | Price Range |
|---|---|---|---|---|
| Yamaha YZ125 | 2-stroke | 6-speed manual | 198 lbs | $$$ |
| KTM 125 SX | 2-stroke | 6-speed manual | 196 lbs | $$$ |
| Honda CRF125F | 4-stroke | 4-speed manual | 194 lbs | $$ |
| Kawasaki KLX140R | 4-stroke | 5-speed manual | 199 lbs | $$ |
| Apollo DB-X18 125cc | 4-stroke | 4-speed manual | 163 lbs | $ |
| SSR SR125TR | 4-stroke | 4-speed manual | 167 lbs | $ |
1. Yamaha YZ125 - Best Race-Ready 125
The YZ125 is a legitimate racing machine that competes in the 125cc two-stroke class at amateur and professional levels. The liquid-cooled two-stroke engine produces a punchy, exciting powerband that rewards skilled riding. The 6-speed close-ratio gearbox keeps the engine in its powerband through corners and straightaways.
This is not a beginner bike. The two-stroke power delivery requires throttle discipline, and the race-oriented suspension is set up for aggressive riding. But for experienced riders who want the thrill of a high-revving two-stroke and the lightest possible race machine, the YZ125 is unmatched. Yamaha reliability means the engine will take a beating and keep performing.
2. KTM 125 SX - Best Handling 125
KTM builds the 125 SX on a chassis that is widely considered the best-handling platform in the 125 two-stroke class. The WP XACT suspension is plush and controlled, the chromoly steel frame is light and rigid, and the hydraulic Brembo clutch is the smoothest in the business. The engine is competitive with the Yamaha, offering slightly more bottom-end punch at the cost of some top-end scream.
Like the YZ125, this is a race bike and not ideal for beginners. The price reflects the premium components and European build quality. For riders stepping up from minis or pit bikes into competitive motocross, the KTM 125 SX is a formidable weapon.
3. Honda CRF125F - Best for Beginners
The CRF125F is purpose-built for new riders. The air-cooled 4-stroke engine produces gentle, predictable power that builds confidence without scary surprises. The 4-speed transmission has wide gear spacing for easy shifting, and the low seat height accommodates shorter riders. Honda reliability means this bike will start every time and require minimal maintenance.
Available with standard or big wheels, the CRF125F grows with the rider. The big-wheel version raises the seat height and adds larger tires for better ground clearance on trails. This is the bike that Honda dealers recommend for families, and it has earned that reputation through years of trouble-free service.
4-6. More 125cc Options
Kawasaki KLX140R: A trail-oriented 4-stroke that splits the difference between the beginner-friendly CRF125F and the race-ready Yamaha and KTM. The 5-speed transmission and slightly more aggressive engine tuning give intermediate riders room to progress. Electric start and fuel injection make it convenient and consistent in all conditions.
Apollo DB-X18 125cc: The most affordable way into a 125cc dirt bike. The Chinese-made engine is adequate for casual trail riding and backyard play. Build quality is basic but serviceable if you inspect and tighten everything before the first ride. A solid choice for families testing whether dirt biking will become a regular hobby before investing in premium machines.
SSR SR125TR: A step up from the Apollo in build quality and reliability. SSR has built a decent reputation in the budget dirt bike market and backs their bikes with a US-based parts and service network. The 4-speed engine is smooth, the disc brakes are adequate, and the suspension handles moderate trails well. Best value in the budget 125cc segment.
2-Stroke vs 4-Stroke at 125cc
The difference is dramatic at this displacement. A 125cc two-stroke (Yamaha YZ125, KTM 125 SX) produces roughly twice the peak horsepower of a 125cc four-stroke (Honda CRF125F, Kawasaki KLX140R). The two-stroke bikes are race machines aimed at experienced riders. The four-stroke bikes are trail and beginner machines designed for learning and casual riding.
Choose a two-stroke if you want to race or ride aggressively. Choose a four-stroke if you are learning, riding trails at a relaxed pace, or buying for a teenager.
Final Recommendation
The Honda CRF125F is the best 125cc dirt bike for most buyers because it serves the largest audience: new riders, families, and casual trail riders. For racing and experienced riding, the Yamaha YZ125 offers unmatched two-stroke excitement. And for budget-conscious buyers, the SSR SR125TR provides the best value in the affordable segment.
