ATC250SX — where Honda’s 2-stroke performance meets trail-ready practicality in a legendary air-cooled 3-wheeler built for serious off-road enthusiasts. For riders who want the raw power of a 2-stroke without the complexity of liquid cooling, the ATC250SX delivers a ride that’s as capable as it is nostalgic. With a 246cc air-cooled 2-stroke engine, 6-speed manual transmission, and rugged chassis, this machine offers the perfect blend of performance, simplicity, and trail versatility.

Unlike its liquid-cooled sibling, the race-bred ATC250R , the ATC250SX was engineered for all-day trail riding—with a more relaxed powerband, durable air-cooling, and practical features like a larger fuel tank and comfortable ergonomics. Whether you’re exploring remote fire roads, tackling hill climbs, or reliving the golden age of 3-wheelers, the ATC250SX ensures you do it with authenticity, power, and legendary Honda reliability.

Pair it with the high-performance ATC250R for racing, or compare it to the 4-stroke ATC200X for low-maintenance trail fun.

Why Choose the ATC250SX?
