Introducing the ProTaper MN/3xD9 ATV CS4 Steel Rear Sprocket, specifically designed for Honda TRX250X models produced between 1987 and 1992. This high-performance sprocket is an essential upgrade for those seeking improved torque and power delivery from their ATV.

The CS4 Steel Rear Sprocket is manufactured using premium quality steel material, ensuring enhanced durability and strength. Its 3xD9 spline design provides superior engagement with the drive chain, reducing slippage and ensuring smoother power transmission.

This sprocket boasts a 42-tooth count, which is ideal for the TRX250X's engine characteristics. The increased tooth count offers better traction, allowing for better acceleration and climb ability. Furthermore, the larger number of teeth ensures a longer chain life by reducing the load on each link.

The CS4 Steel Rear Sprocket's unique MN series design features a narrower width than stock sprockets, which results in reduced unsprung weight. This weight reduction leads to improved handling and agility, allowing you to tackle the toughest terrain with confidence.

Installation of the ProTaper MN/3xD9 ATV CS4 Steel Rear Sprocket is straightforward, requiring no modification to the ATV's drivetrain. Simply replace the stock sprocket with this high-performance upgrade, and enjoy the enhanced power and torque delivered to your wheels.

Upgrading to the ProTaper MN/3xD9 ATV CS4 Steel Rear Sprocket is an investment in your ATV's performance and durability. This premium component is perfect for riders who demand the best from their off-road machine and seek to push their limits on the trail.

The Protaper MN/3xD9 atv CS4 steel rear sprocket is a popular aftermarket option for the 1987-1992 Honda TRX250X ATV. This sprocket offers several benefits and drawbacks that are important to consider before making a purchase.
