I am going to purchase an ATV to use predominantly for ice fishing  There is a local dealer in town and I am narrowing my choices to Honda, Yamaha, and cfmoto.  I am looking at the 420 rancher and the cfmoto 400 as my two best choices.  Anyone out there with experience with the 400?

As a dealer I can tell you its a solid machine, and best in its class, especially for the price and warranty. I've sold two so far (they just came out) and have had ZERO complaints or issues. I believe they will do very well for me for the years to come. The 400 runs a BOSCH EFI system that is rock solid.
