One of Honda’s most loved ATVs, the TRX420FM1 sets the benchmark for rugged durability.  With a reliable and economical 420cc engine this 4WD manual makes easy work of hilly terrain. Throttle response and economy are helped by the latest version of Honda’s Programmed Fuel Injection (PGM-FI) system. The new TRX420FM1 has revised carry racks, and a new built-in front storage component which is perfect for storing keys, a phone, or similar you need to keep safe. 

It’s equipped with a double-cradle steel frame designed for precise handling and a smooth ride without compromising strength, 170mm of travel in both the front and rear suspension systems ensures a plush and controlled ride, and new guards extending the full length of the lower suspension arms provide full coverage of the driveshaft and outboard CV joints which helps protect the running gear of the bike and further improves the durability of this model!
