Honda makes a good bike no doubt but from what I have heard from several people that have bought the AT they have had some problems with them. Most of the people I have spoken with have had electrical problems, heating issues, transmission problems, cooling pumps going out, etc
Needless to say there are some definite issues.
I have ridden the Honda transmission on a Rincon and the CVT on Grizzly, Polaris, Arctic Cat, etc
I guess the best comparison would be the Rincon 650 vs. my Grizzly 660. Like I said before two bikes with the same size engine and one just out powers the other easily. It has nothing to do with the engine, but its all in the transmission.
Its true that most autos out there have a CVT transmission in them, but then again you would have to look at why they have them. First off the CVT is a pretty basic style of transmission and it is not only easy to work on, but also not that expensive. Secondly the CVT does an excellent job of putting the power to the ground because you dont have the conventional transmission that will suck up a whole lot of the power getting it to the wheels. Thirdly you have the fact that the CVT transmission is extremely proven while the transmission in the 400AT and Rincon are not quite as proven. The CVT has been used for many, many years in snowmobiles and other various machines. The design is simplistic and it works
With the Honda transmission used on the AT and Rinny you have a whole different ball game. There is no way that a normal every day Joe could work on it if you had problems. You would have to take it to a shop and have it worked on and those transmissions are quite expensive to fix. When I go look at a new bike I dont really pay attention to the price of the bike, but rather look at how much it will cost to fix it. When I looked at the CVT I said Well, its simple and if I break down I know I can fix it even if I am out in the field. The I looked at the Honda and said Man, if that thing breaks down in the field I will never be able to fix it and its going to cost me an arm and a leg.
Dont get me wrong I am not trying to make the Honda sound like a bad bike. I have always been a fan of Hondas and I even still now own Honda, but you cant deny the mass problems some people have been having with the new set-up Honda has been using. Also this is not to say that all people will have these problems. I thought about the axle problems the Grizzly has when I was buying mine, and even though most people break theirs fairly easy mine have lasted me a year and I have only broken one. All bikes are different and some might not have problems while others do. When you have mass problems is when you have to look at it.
