Kestrel Take
A capable mid-size utility quad — Arctic Cat's Alterra 600 offers good power, a comfortable ride, and solid features, an alternative to the Polaris/Yamaha/Honda machines, often at a slightly better price. Same belt-drive, mud/water, and CV-boot inspection, plus verify parts/dealer access. A well-kept, un-drowned Alterra 600 is a capable value utility quad; check the belt, clutch, airbox, and boots and confirm it wasn't a mud machine.
