I am looking at getting another quad. Here's the story...... I am 28 and haven't been on a quad in 6 years other than my dad's Polaris 325. I have ridden dirtbikes and/or quads since I was 4. The last two quads I had were both National bikes. A 250r for MX and a Quadracer for TT. I raced local and National 250B for a few years back in my younger days. This time around I am looking for a quad I can trail ride and possibly race harescrambles and maybe even show-up at a few local fair mx races. I don't mind adding a few bolt-ons (pipe, shocks, axle, etc.), but I want the motor on my next quad to remain stock for reliability. I have narrowed it down to a new Z400 or used 400ex & the 250r. I really like to Z but I am not sure I want to spend the cash for a new bike. My buddy who just did a total restoration on his 86 250r rode a Z and didn't seem totally thrilled afterward. I am yet to ride one. Also, I am a little concerned about the reliablilty of the Z since it's new. Though I have had good luck out of both Suzukis I have owned in the past. Honestly, right now I am leaning more toward a used 400ex. Which is it the Z400, 400ex, or 250r? I'd like to hear your thoughts.
