The machine
The 2026 Husqvarna TC 125 is a race-focused motocross machine designed to withstand the demands of competition and intended for use on designated tracks away from public roads. It relies on electronic fuel injection with a cold-start button to aid cold starts, and it includes an electric starter for quick fire-up. The hydraulically actuated clutch self-adjusts, while the front brake is operated from the right-hand lever. The chassis features XACT air suspension and a fork air‑pressure adjuster, with a left‑side combination switch that toggles Lean and Rich throttle mappings to suit firm or loose surfaces. A dashboard hourmeter records engine hours as you ride, and the bike carries specific identifiers such as VIN 401945-10 and engine number H01047-10 for traceability. Safety notes and intended-use guidelines emphasize riding on tracks and proper protective gear.
Who should ride it
This bike is built for riders who want precision and performance on motocross tracks. It suits a hare scrambles racer seeking lightweight, responsive handling, or a weekend motocross rider who prioritizes consistent power delivery, adjustable mapping, and advanced suspension. It demands a committed rider with track-focused goals and the discipline to operate within designated riding areas.
