Historical Background

In particular, Honda ATVs’ TRX series are designed to take a beating while cruising rugged off-road trails. The first TRX 300EX model was introduced by Honda in 1993 as a replacement for the then-powerful and successful TRX250X sport ATV.



One of the most reliable ATVs ever made, the 300EX has electric starting and an additional 36cc of displacement from its predecessor. Following the 2009 model, the TRX 300X (2009-2021) replaced the TRX 300EX but retained the same features. Despite this, the TRX 300EX has all the features of a modern ATV, and its engine is capable of running continuously all day.

Honda TRX 400EX has a SOHC 282 cc four-stroke engine along with a single cylinder. It has a liquid cooling system that is used to prevent the engine from overheating. It also has a 74 mm x 65.5 mm Bore and Stroke ratio and an 11.5:1 compression ratio.

Moreover, it has a 32 mm piston-valve carburetor with an accelerator pump and a CD with electronic advanced ignition and an electrical starter. Lastly, for the transmission section, it has a five-speed gearbox with a reverse option powered by an O-ring-sealed chain.  


 In the front, it has an independent double-wishbone suspension with dual hydraulic shocks and a five-position spring preload adjustment. For the rear, it has a Swing arm with a single shock suspension with five-position spring preload adjustment. The front suspension has 6.7 inches of wheel travel, and the rear suspension has 7.9 inches of travel. These suspensions are adequate, providing a good riding experience by absorbing the bumps and jolts.


 It has a dual hydraulic disc brake for the front wheel and a single hydraulic disc for the rear wheel as well. Both of these brakes are excellent at work, providing outstanding performance and safety even when speeding.  


It has a 22 x 7 – 10 knobby front tire and a 22 x 10 – 9 knobby rear tire. Both of these tires are also excellent, providing outstanding grip on the road and preventing skidding. 

Dimensions & Weight

In terms of length, width, and height, it measures 67.7 inches, 43.5 inches, and 42.7 inches, respectively. Along with that, it has a decent 45.3-inch wheelbase and 4.9-inch ground clearance, but the only thing it lacks is its 30.3-inch seat height. Lastly, since it weighs 377 pounds, you can easily haul it wherever you want.  

Performance and Top Speed

The Honda TRX 300EX’s top speed is 50 – 52 mph with a maximum power of 15.8 kW at 7000 rpm and maximum torque OF 23.1 Nm at 6000 rpm. While this speed is adequate for off-roading, it is not recommended for hill climbing.

Price & Competitors

There is no new model available, but you will be able to get a Honda TRX 300EX in pre-loved condition for $2,499 – $3,500. Aside from that, its competitors are the Yamaha Raptor 250 and Raptor 350. Both of them are also excellent quads, but in my opinion, 300EX is the finest for having excellent brakes and knobby, along with the moderate power engine.


The Honda TRX 300EX was launched in 1993 as a replacement for TRX250X. Until recently, it was one of the most rigid and reliable four-wheelers in existence. Also, you will get an adequate suspension on this quad that ensures a smooth ride at slow speed. 

Additionally, the brakes and tires on this ATV are excellent and still compete with those on newer models. Lastly, it comes at an affordable price, which makes it a great buy.
