Ira's
Suzuki Z-400
My friend just got one of these. I went over there and tested it. It is a great machine. Excellent suspension, awesome power and good ergonomics make this fun and exciting to drive. It's set up is alot like the 400ex. both have the same feel to them. They finally got there act together and built a good sport machine that will give the other quads a run for the money.
