I have had the Kodiak 400 for 6 years now and have no complaints. I am not sure about the miles since I do not have a speedometer. The bike has been very reliable and is the perfect size for hunting and trail riding. Other, bigger bikes are faster but if you are not racing, the Kodiak is plenty fast enough. Get a sports quad if you want to go faster.
The straight axle worked fine until I rode the newer Kodiak with the independent rear suspension. The IRS makes trail riding much smoother.
I have rode with others that had the Big Bear, Grizzly, Polaris 600 and two have recently bought new Kodiaks.
