So I am trying to decide which one to buy off craigslist.
Blaster 2006 Yamaha Blaster (street legal in AZ)
TRX400EX ATV honda and kawasaki
Never had either of these before or ridden them. The Honda is cheaper and ive read that they are more reliable but the Yamaha is newer and looks cleaner. Juts wanted to know what you guys think. Thanks!

 

So, that Honda is a 300EX. If they turn out as advertised, You could buy the Honda/Kawi combo and turn around and sell the one you don't want. The low price is suspicious to me though. The Blaster looks brand new. In that mildly modded form they will run a long time provided you use good gas/oil and keep the air filter serviced. While 2 strokes need new top ends sooner than 4 strokes in general, it is easier and a much cheaper job to perform.

 

I would get the Honda 400, 4-strokes are much more reliable, 2-strokes are fast and fun but can be a pain. As a example I got a 2001 Yamaha Blaster September 2011, I only got to ride it 2 times in a year and half. I've had both quads and the 400 will hold up for a long time.
