Review RACE DRIVEN Honda 400ex Tooth Front And 38 Rear Silver Sprocket fits TRX400EX 1999–2014

Introducing the Race-Driven F-28956 Sprocket Set, specifically designed for the Honda TRX400EX and 400EX models produced between 1999 and 2004. This high-performance sprocket set is an excellent upgrade for those seeking enhanced power delivery and improved acceleration for their all-terrain vehicle.

The front sprocket in this set is a 14-tooth design, which offers a more aggressive power delivery compared to the stock 15-tooth sprocket. This results in quicker acceleration and a more responsive riding experience. The front sprocket is made from strong, lightweight aluminum, ensuring durability and longevity.

The rear sprocket in this set is a 38-tooth design, which provides optimal gear ratio for the 400EX and 400EX models. This tooth count is well-suited for off-road riding, offering a balance between top speed and low-end torque. The rear sprocket is made from heat-treated steel, ensuring strength and resistance to wear and tear.

The Race-Driven F-28956 Sprocket Set is precision-machined to ensure a perfect fit and smooth engagement between the sprockets and the drive belt. This set includes both the front and rear sprockets, as well as the necessary hardware for installation.

By upgrading to this high-performance sprocket set, you'll experience improved acceleration, increased power delivery, and enhanced overall performance for your Honda TRX400EX or 400EX. This is an excellent choice for riders who demand the best from their off-road vehicle and are looking to take their riding experience to the next level.

The Honda TRX400EX, produced between 1999 and 2004, is a popular all-terrain vehicle (ATV) known for its durability and versatility. One common upgrade for this model is changing the stock sprocket sizes, often to a 14T front and 38T rear configuration. Let's discuss the pros and cons of purchasing such an upgrade for your TRX400EX.

1. Increased Top Speed: A larger rear sprocket reduces the number of engine RPMs required to turn the wheels at a given vehicle speed. This results in a higher top speed.

2. Improved Power Delivery: A larger rear sprocket can help improve power delivery, making the ATV feel more responsive and powerful, especially when climbing hills or towing heavy loads.

3. Better Hill Climbing Ability: The increased torque generated by the larger rear sprocket helps the ATV climb steep hills more easily.

1. Reduced Low-End Torque: A larger rear sprocket results in fewer engine RPMs at a given vehicle speed. This can reduce the amount of torque available to the wheels at lower speeds, making it harder to accelerate and maneuver in tight spaces.

2. Higher Engine Revs: With a larger rear sprocket, the engine will need to rev higher to maintain the same vehicle speed. This can lead to increased engine wear and may require the use of a high-performance exhaust or other modifications to ensure the engine operates efficiently.

3. Longer Transmission Life: The increased stress on the transmission caused by the larger sprockets can lead to shorter transmission life, requiring more frequent maintenance or replacement.

In conclusion, upgrading your Honda TRX400EX with a 14T front and 38T rear sprocket can provide increased top speed, improved power delivery, and better hill climbing ability. However, it also comes with the drawbacks of reduced low-end torque, higher engine revs, and potentially shorter transmission life.

Ultimately, the decision to purchase this upgrade depends on your specific riding needs and preferences. If you frequently ride on flat, open terrain and prioritize top speed and power delivery, this upgrade may be worth considering. However, if you often ride in tight spaces, climb steep hills frequently, or have concerns about engine wear and transmission life, you may want to consider other modifications or continue using the stock sprocket sizes.

If you decide to pursue this upgrade, ensure that you use high-quality sprockets and a compatible chain. Additionally, consider other modifications, such as a high-performance exhaust or clutch kit, to help maintain engine efficiency and longevity. Regular maintenance, including transmission checks and oil changes, is also crucial to ensure the longevity of your ATV.
