Review RACE DRIVEN Honda 400ex Tooth Front And 38 Rear Black Sprocket fits TRX400EX 1999–2015

Introducing the Race-Driven F-400138 Sprocket Set, specifically designed for Honda TRX400EX and TRX400X models produced between 1999 and 2004. This high-performance sprocket set is an excellent upgrade for those seeking improved acceleration, increased power output, and enhanced durability for their ATV.

The front sprocket measures 15 inches in diameter and is machined from robust, heat-treated steel. Its precise design ensures optimal tooth engagement with the rear drive chain, delivering unrivaled power transfer and efficiency. Additionally, this front sprocket features a slimmed-down design, reducing unsprung weight for a more responsive and agile ride.

The rear sprocket, with a diameter of 38 inches, is meticulously crafted to match the front sprocket, ensuring perfect harmony between the two components. Made from the same high-quality, heat-treated steel, it boasts an increased number of teeth, which results in a shorter final drive ratio. This modification provides a significant boost in acceleration and overall vehicle performance.

The Race-Driven F-400138 Sprocket Set is an essential upgrade for enthusiasts looking to extract the maximum potential from their Honda TRX400EX or TRX400X. By improving power transfer efficiency, reducing unsprung weight, and enhancing durability, this sprocket set guarantees a more exhilarating and enjoyable riding experience.

Installation is a straightforward process, and the set comes with all necessary hardware for a hassle-free installation. For those seeking top-tier performance, agility, and durability for their Honda ATV, the Race-Driven F-400138 Sprocket Set is the perfect choice.

The Honda TRX400EX, also known as the F-400138 model with a 15T front and 38T rear sprocket, is a popular choice among ATV riders due to its durable design, powerful engine, and versatile capabilities. However, like any other vehicle, it comes with its pros and cons.

Pros:

1. Powerful Engine: The TRX400EX is equipped with a 397cc liquid-cooled engine that delivers excellent power and torque, making it ideal for various terrains and riding conditions.

2. Durable Design: Honda's reputation for building high-quality vehicles is well-deserved. The TRX400EX's frame and components are designed to withstand the rigors of off-road riding, ensuring long-lasting performance.

3. Versatile: This ATV is suitable for a wide range of riding styles and terrains, from trail riding to mud bogging and even racing.

4. Comfortable: The TRX400EX features a comfortable and ergonomic design, with a plush seat, adjustable handlebars, and ample legroom, making long rides enjoyable.

5. Reliable: Honda's reputation for reliability means that the TRX400EX is a dependable vehicle that requires minimal maintenance.

Cons:

1. Heavy: Weighing in at over 600 pounds, the TRX400EX can be challenging to maneuver, especially for inexperienced riders or those with limited strength.

2. Expensive: Compared to other ATVs in its class, the TRX400EX can be quite pricey, both in terms of purchase price and ongoing maintenance costs.

3. Limited Suspension Travel: While the TRX400EX's suspension is capable, it doesn't offer the same level of travel as some of its competitors, which can make it less effective in extreme terrain.

4. Limited Storage: The TRX400EX has limited storage capacity, which can be a drawback for riders who need to carry extra gear or supplies.

In conclusion, the Honda TRX400EX with a 15T front and 38T rear sprocket is a powerful, durable, and versatile ATV that offers a comfortable riding experience. However, its heavy weight, high price tag, limited suspension travel, and storage capacity may be drawbacks for some riders. Ultimately, if you prioritize power, reliability, and comfort, the TRX400EX is an excellent choice. However, if you require more storage or suspension travel, or if budget is a concern, you may want to consider other options.

Recommendation:

If you're looking for a powerful and reliable ATV with excellent handling and a comfortable riding experience, the Honda TRX400EX is an excellent choice. However, if you require more storage or suspension travel, or if budget is a concern, you may want to consider the Yamaha Grizzly 450 or the Polaris Sportsman 500. Both of these ATVs offer more storage capacity and better suspension travel than the TRX400EX, while still providing strong performance and durability. Ultimately, the best ATV for you will depend on your specific needs and preferences.
