# Ultimate Guide to CFMOTO 800NK Sprocket: Upgrade, Maintenance & Performance Tips
Unlocking the full potential of your CFMOTO 800NK often starts with a component many riders overlook: the sprocket. This crucial part of your drive system directly influences acceleration, top speed, fuel efficiency, and overall ride feel. Whether you’re looking to upgrade for performance, need maintenance advice, or want to fine-tune your bike’s character, this guide covers everything you need to know about the **CFMOTO 800NK sprocket**.
## **Detailed Function and Impact**
The sprocket, working in tandem with the chain, is responsible for transferring power from the engine’s output shaft to the rear wheel. Changing its size is one of the most cost-effective modifications you can make.

Choosing the Right Sprocket Setup
**
Your choice between steel and aluminum sprockets, and the number of teeth, will define your ride.
Material Showdown: Steel vs. Aluminum
* **Steel Sprockets:** Known for exceptional durability and longevity. They are heavier but can withstand significant wear and tear, making them ideal for high-mileage touring or everyday commuting.
* **Aluminum Sprockets:** Much lighter, reducing unsprung rotational mass. This can lead to slightly quicker acceleration and improved suspension response. However, they wear faster and are typically chosen for performance-oriented or competitive riding.
Tooth Count and Gearing Changes
* **Decreasing Rear Teeth (or Increasing Front):** Creates taller gearing. This can increase top speed and potentially improve highway fuel economy, but may reduce low-end acceleration.
* **Increasing Rear Teeth (or Decreasing Front):** Creates shorter gearing. This delivers snappier acceleration, better wheelie control, and improved hill-climbing ability, at the expense of higher RPMs at cruising speed and potentially lower top speed.
## **Step-by-Step Maintenance & Replacement**
Regular maintenance is key to safety and performance. For a comprehensive selection of quality parts, including a durable **cfmoto 800nk sprocket**, visit trusted suppliers.
1. **Regular Inspection:** Check for hooked, worn, or cracked teeth. Inspect the chain for proper tension and lubrication.
2. **Cleaning:** Keep the sprocket and chain free of grime and old lubricant to prevent accelerated wear.
3. **Replacement Signs:** Replace the sprocket if you see significant tooth wear, especially a “shark fin” shape. *Always replace the chain and both sprockets as a set* to prevent uneven wear and premature failure.
## **Frequently Asked Questions**

Common CFMOTO 800NK Sprocket Questions
**
**Q: Will changing my sprocket void my CFMOTO warranty?**
A: Typically, no. Modifying the sprocket is generally considered a routine customization that does not affect the engine or core warranty. However, always check your warranty booklet or with your dealer for confirmation.
**Q: How often should I replace my sprockets?**
A: There’s no fixed mileage. They should be replaced as a set with the chain. A well-maintained chain and sprocket set can last 15,000-20,000 miles or more, but aggressive riding or poor maintenance will shorten this lifespan.
**Q: What’s the best all-around sprocket setup for street riding?**
A: For balanced street performance, most riders stick with the stock tooth count or opt for a +1 or +2 increase on the rear sprocket for more responsive acceleration in city traffic, without overly compromising highway comfort.
