The Protaper SPRT-KFX450-38T CS4 rear sprocket is a popular aftermarket option for the Kawasaki KFX450R models from 2008 to 2014. Here are some pros and cons to help you make an informed decision about whether to buy this sprocket.

Pros:

1. Increased Top End Power: A larger rear sprocket like the 38T provides more top-end power by reducing the number of revolutions per mile. This can be beneficial for riders who prefer a more responsive and agile ATV.

2. Improved Acceleration: With a larger sprocket, the engine will rev faster, resulting in improved acceleration and quicker hole shots.

3. Customization: The Protaper sprocket is a high-quality aftermarket option that allows riders to customize their ATVs to their specific riding style and preferences.

4. Durable: Protaper is a reputable brand known for producing high-quality components. The SPRT-KFX450-38T CS4 rear sprocket is no exception, and it is built to last.

Cons:

1. Reduced Torque: A larger rear sprocket reduces the amount of torque, which can make the ATV less stable at low speeds and when carrying heavy loads. This may not be ideal for riders who frequently ride in rough terrain or carry passengers.

2. Increased RPMs: The larger sprocket results in increased engine RPMs, which can lead to higher engine wear and tear over time.

3. Cost: The Protaper SPRT-KFX450-38T CS4 rear sprocket is more expensive than the OEM sprocket. While the quality and performance benefits may justify the cost for some riders, others may prefer to save money and stick with the stock component.

Ending Conclusion:

The Protaper SPRT-KFX450-38T CS4 rear sprocket is an excellent aftermarket option for riders who prioritize top-end power, acceleration, and customization. However, it may not be ideal for those who frequently ride in rough terrain, carry heavy loads, or prefer a more stable ATV. Ultimately, the decision to buy this sprocket depends on your riding style, preferences, and budget.

Recommendation:

If you are a rider who values responsive acceleration and top-end power, and you are willing to invest in a high-quality aftermarket component, the Protaper SPRT-KFX450-38T CS4 rear sprocket is an excellent choice. However, if you prioritize torque, stability, and cost savings, you may want to stick with the OEM sprocket or consider other aftermarket options with smaller sprocket sizes.
