2013 Honda Trx 400x Pre Owned, There are plenty of things you can say about the Honda TRX400X, but to fully understand it, you have to experience it. That s because underneath the race-style bodywork lies everything the warrior ATV rider needs, starting with the SOHC, 397cc, air-cooled, dry-sump RFVC (Radial Four-Valve Combustion Chamber) engine. Then there s the triple-disc brakes. Baja-ready Pro-Link® suspension with long travel. Standard reverse and all the reliability you d expect from a Honda. We ve even given it all-new graphics for an even more aggressive look.
