  • trx400ex
    By mike nixon (I am an Owner) on Apr 28, 2019

    I love this bike - it rips and it also oddly goes in the back of my ranger with the gate closed. Parts are plentiful and it turns good. The could have done a little better job on the plastics.

  • WOW, it gets it!
    By chris barba (I am an Owner) on Aug 02, 2015

    I traded a 2009 ninja 250r for mine and was not sure if it was a good trade. Let me tell you, this atv will get it. Through the jumps it floats and will land full throttle and leave you in the dust. I raced a 660 raptor and beat his rear on top end speed. Do not get me wrong, it has after market ...

  • My four-wheeler.
    By courtney crase (I am an Owner) on Aug 07, 2014

    Having a Honda sportrax 400ex is the best sport ATV you can own. It rides great, up and down hills. It rides in the mud like it owns it, and don't get me started on the gas. I can fill it up and ride for so long and still have gas in my tank, that's the best feeling any rider can have. I love my ...

  • Great atv!
    By Garrett Corry (I am an Owner) on Dec 16, 2012

    Ok, this atv is great! It does NOT have reverse, so dont be fooled. Even though its not the fastest or most powerful, but it is BULLETPROOF! I reccomend you buy a 14 tooth front sprocket to gain more torque, but you will lose a little top end speed. Stock, you will get about 64 mph, but it depends ...

  • 2002 400ex
    By Dennis (I am an Owner) on Nov 18, 2012

    This is my first ATV I have owned. I have ridden many other ATV's but each one I have ridden needs repairs often. So I decided to buy the 400ex. This is a great ATV. I have ran it against many ATV's either runs with them or not much behind them. This is a great ATV and I love it. It does whatever ...

  • I own a 2002 model but practicly the same
    By Chucky (I am an Owner) on Oct 23, 2012

    I own a 2002 Honda TRX400EX this year(2012). This is my first atv I've owned. I have rode others before, but not a manual. The previous owner had rolled it over on its top or something to that effect. I'm not sure what for sure because I bought it from a dealership. I also had wrecked it myself pretty ...

  • SUPER ATV SUPER RELIALBLE
    By David Johnson (I am an Owner) on Apr 28, 2009

    This ATV is a great quad for beginners to pro. It is awesome for trail riding and easy to use the clutch. Maybe a little bit more power but with a few add ons you can change that for sure!!
