Crafted from premium CS4 steel, this sprocket boasts superior strength and resistance to wear and tear.

This sprocket features a 2.5mm pitch, which is suitable for most aftermarket drive chains. The 16mm bolt pattern ensures a secure fit to the rear wheel hub, while the 520mm outer diameter allows for proper clearance and chain tension.

Installation of this sprocket is straightforward, ensuring a hassle-free upgrade process. This product also comes with a new drive collar, making it a complete kit for those seeking to replace their worn-out stock sprocket and collar assembly.

By upgrading to the ProTaper MN/86Z4 ATV CS4 Steel Rear Sprocket, riders can expect improved acceleration, increased power delivery, and enhanced durability for their KTM 450 XC models. This sprocket is an essential upgrade for those who demand high-performance components for their off-road adventures.

The Protaper MN/86Z4 CS4 steel rear sprocket is a popular aftermarket option for the 2008-2009 KTM 450 XC-F models. This sprocket is designed to provide better durability and performance compared to the OEM sprocket. Here are some pros and cons of buying this sprocket:

Pros:

1. Enhanced durability: The CS4 steel material used in this sprocket is stronger than the OEM alloy sprocket, making it more resistant to damage, especially during off-road riding.

2. Better power delivery: The larger tooth pitch of the Protaper sprocket allows for smoother power delivery and reduced engine drag, which can result in improved acceleration and overall performance.

3. Customizability: The Protaper sprocket comes in various sizes to suit different riding styles and terrain conditions, allowing riders to fine-tune their ATV for optimal performance.

Cons:

1. Higher cost: The Protaper MN/86Z4 CS4 steel rear sprocket is more expensive than the OEM sprocket.

2. Potential noise: Some riders have reported that the Protaper sprocket can be louder than the OEM sprocket, especially during high-speed riding.

3. Requires chain adjustment: Installing a new sprocket may require adjusting the chain tension to ensure proper fitment and function.

In conclusion, the Protaper MN/86Z4 CS4 steel rear sprocket offers several advantages over the OEM sprocket, including enhanced durability, improved power delivery, and customizability. However, it comes with a higher cost, potential noise, and the need for chain adjustment. If you prioritize durability, performance, and the ability to fine-tune your ATV, then the Protaper sprocket is a worthwhile investment. However, if you are on a tight budget or prefer a quieter ride, the OEM sprocket may be a better option for you.
