The 2026 Yamaha YZ125X is built for riders who want lightweight two-stroke performance, razor-sharp handling, and serious cross-country capability.

Developed from Yamaha’s legendary YZ125 motocross platform, the YZ125X combines aggressive 2-stroke power delivery with off-road-focused tuning to create one of the most exciting and confidence-inspiring lightweight enduro bikes in the Yamaha lineup.

Powered by a high-performance 125cc liquid-cooled 2-stroke engine, the YZ125X delivers crisp throttle response, explosive acceleration, and the exciting high-revving powerband that makes lightweight two-strokes incredibly fun to ride across technical trails, tight single track, and fast off-road terrain.

The lightweight aluminium semi double cradle chassis, premium KYB suspension package, and race-developed ergonomics provide exceptional agility, rider feedback, and control through rough terrain, ruts, rocks, climbs, and technical enduro sections.

Purpose-built for off-road riding, the YZ125X features off-road suspension settings, an 18-inch rear wheel, larger rear tyre profile, side stand, sealed O-ring chain, and cross-country focused setup designed to maximise performance in real off-road conditions.
