TRX400X

-- THE QUAD THAT CHANGED THE SPORT -- The ‘90s were the dark ages in ATV history. Sport quads vanished, ATV manufacturers retreated and the forces of mediocrity and bureaucracy advanced, threatening to overrun anyone who dared to ride a quad for the pure joy of it. Then, in model year 1999, that entire era came to a close with the appearance of one ground-breaking machine: the Honda TRX400EX. From that point on, the sport would never be the same. The Honda 400 was a game changer on several levels. First, it was the…

Another year has passed, which means new and exciting ATV models have hit the market. Nowadays, these machines are coming with more features at better price points.

Since its first year of production in 1999, Honda’s TRX400EX has a reputation for being one of the most durable and fun sport ATVs of all time. The design of the TRX hasn’t changed too much in its lifetime because it never needed to. The air-cooled four-stroke engine is practically bulletproof, the lack of liquid cooling greatly reduces complexity, and you can adjust the valves with hand tools. There are lots of riders who love the “keep it simple” philosophy. The chassis is likewise basic, but it handles well and has plenty…

From the beginning of time the Honda 400EX has been one of the top machines to have. With its great suspension geometry, powerful engine and all-around good handling, it makes for a perfect platform to upgrade or leave stock. Honda first introduced its 400 motor in the XR400 dirt bike, and in 1999 put that same motor, with a few slight modifications to beef it up internally, in the quad. Now, 16 years later, we still have the same reliable machine with an updated look and a reverse gear. The ATV world now has a variety of…
