Introducing the ProTaper MN/6NCJ ATV CS4 Steel Rear Sprocket, an exceptional upgrade for your 1999-2008 Honda TRX400EX Sportrax HX. This high-performance sprocket is meticulously crafted to deliver superior strength, durability, and efficiency for your all-terrain vehicle.

The ProTaper MN/6NCJ ATV CS4 Steel Rear Sprocket is engineered using premium quality, heat-treated steel. This material ensures that the sprocket can withstand the rigors of off-road riding, providing you with the confidence to tackle the toughest terrain. The steel construction also offers increased strength compared to the OEM sprocket, ensuring that it can handle higher torque loads and maintain its shape under heavy use.

One of the standout features of this ProTaper sprocket is its CS4 tooth design. The CS4 teeth offer a more aggressive engagement with the O-ring chain, providing smoother power transfer and reducing the risk of chain jump. This results in improved acceleration, better traction, and overall enhanced performance.

The ProTaper MN/6NCJ ATV CS4 Steel Rear Sprocket also comes with a 6-bolt pattern, ensuring a secure fit on your Honda TRX400EX Sportrax HX. The sprocket's precision machining ensures a perfect fit, eliminating any potential wobble or play, resulting in a quieter and more efficient ride.

Another advantage of this ProTaper sprocket is its lightweight design. Despite its increased strength and durability, the sprocket weighs less than the OEM sprocket, reducing unsprung weight and improving your ATV's agility and handling.

Upgrading to the ProTaper MN/6NCJ ATV CS4 Steel Rear Sprocket is an excellent investment for any Honda TRX400EX Sportrax HX rider looking to improve their vehicle's performance and reliability. With its superior strength, efficiency, and aggressive tooth design, this sprocket is sure to provide you with a more enjoyable and capable off-road experience.
