    I bought my 400ex brand new in 2010 from a dealer. I kept it stock for about a year than added nerf bars fmf Q4 slip, on air filter, and jet kit. Good power it keeps up with my buddies. I love how it's simple and reliable. Ive never had any problems I recommend this to some one who wants good power ...

    By Ben (I am an Owner) on May 28, 2012

    I have a 2008 honda TRX 400ex. It has all the power that a person will need. Mine keeps up with and even beats 450s when I race it. The only bad thing about the honda 400 is that is uses oil a lot and it doesn't have EFI. But other than that it is a very good machine.

    For a 400cc it's got the get up and go and the other thing you can't beat is the Reverse on it.. Believe me I had to use this many of time's, LOL. Plus I have done the regular Main. on it and it's been still the same as when i got it home from dealer back in 2008.
