The Honda TRX ATVs are typically equipped with either four-wheel drive (4WD) or all-wheel drive (AWD) systems, depending on the specific model and year of production. Four-wheel drive systems are designed to provide power to all four wheels of the vehicle, which can improve traction and stability on rough or slippery terrain. All-wheel drive systems are similar to four-wheel drive systems in that they provide power to all four wheels of the vehicle, but they are typically more complex and sophisticated, and they are able to automatically adjust the power distribution to the wheels based on the traction and stability needs of the vehicle.
