Offering one of the best sport ATV engines Honda has ever produced—a 397cc air-cooled, dry-sump design, 
the TRX400EX is an awesome performer. The rest of this race-spec machine is first-rate too, boasting triple disc 
brakes, long-travel suspension, reverse, aluminum wheels, and new for 2008, slick new styling that now makes
this TRX even harder to beat.
