The mileage at which a Polaris Sportsman is considered to have high miles will depend on a variety of factors, including the specific model and year of production, the quality of the vehicle's maintenance and care, and the operating conditions it has been subjected to. In general, a Sportsman with more than 50,000 miles could be considered to have high mileage, although some models may be able to go much farther before reaching high mileage. It is important to note that the mileage at which a vehicle is considered to have high miles is subjective, and the actual condition of the vehicle is a more important factor in determining its value and reliability.

The high gear setting is designed for maximum speed and performance, while the low gear setting is designed for maximum torque and traction. The specific gear setting that is best for a particular situation will depend on the terrain, the vehicle's load, and the driver's skill and experience. It is always a good idea to refer to the manufacturer's recommendations for the proper use of the vehicle's gears and to use caution and common sense when driving on any terrain.
