A rugged, entry-level trail bike designed for taller or growing riders — the 2026 CRF125F Big Wheel packs a 125cc air-cooled 4-stroke engine with fuel injection for smooth, reliable power. It uses a 4-speed transmission (just like a full-size dirt bike), has a 31 mm front fork and Pro-Link rear suspension tuned for trail duty, and features a 220 mm front disc brake + 95 mm rear drum. The “Big Wheel” trim gives it 19? front / 16? rear wheels, raising the seat height to about 30.9? and increasing ground clearance to ~10.3?. Weighs in at ~199 lb and holds a 1.0-gallon fuel tank.
