# Ultimate Guide to CFMOTO 800NK Sprockets: Performance, Upgrades & Maintenance
**
Understanding Your CFMOTO 800NK Sprocket
**
The sprocket on your CFMOTO 800NK is far more than a simple metal cog. It’s a critical component of the final drive system, working in concert with the chain to transfer power from the transmission to your rear wheel. The stock configuration is designed for a balanced mix of performance, longevity, and fuel efficiency. However, riders often seek to alter their bike’s character through sprocket changes.
**
The Impact of Sprocket Ratios on Performance
**
Changing your sprocket size directly alters the final drive ratio. A larger rear sprocket (or a smaller front sprocket) increases acceleration and improves low-end torque, making the bike feel more responsive in city riding and wheelie-prone. This is often called “gearing down.” Conversely, a smaller rear sprocket (or a larger front) reduces engine RPM at highway speeds, potentially increasing top speed and improving fuel economy—this is “gearing up.” For the 800NK, a common upgrade is to install a high-quality aftermarket cfmoto 800nk sprocket tailored to your specific riding style.

Choosing the Right Upgrade: Materials and Tooth Count
**
When upgrading, you’ll encounter sprockets made from steel, aluminum, or hybrid materials. Steel sprockets are incredibly durable and offer the longest lifespan, making them ideal for high-mileage touring. Aluminum sprockets are lighter, reducing unsprung weight for slightly improved suspension response and acceleration, but they wear faster. The tooth count is your primary tuning tool. Even a one-tooth change on the rear sprocket can create a noticeably different riding experience.
**
Essential Maintenance for Longevity
**
Your sprocket and chain are a wear-matched set. Always inspect your sprocket for signs of wear like hooked or pointed teeth, which indicate it’s time for replacement. Never install a new chain on a worn sprocket, as this will cause rapid chain wear. Regular cleaning and proper lubrication of the entire drive system are paramount.

Frequently Asked Questions (FAQ)
**
Q: How do I know if my CFMOTO 800NK sprocket needs replacing?
A: Look for visibly worn, hooked, or sharp teeth. Also, replace it if you’re installing a new chain or if the chain shows inconsistent tension.
Q: Should I change the front, rear, or both sprockets?
A: For significant ratio changes, start with the rear sprocket. Changing the front sprocket by one tooth has a more pronounced effect. Always replace both sprockets and the chain as a set for optimal performance and safety.
Q: What are the benefits of a lighter sprocket?
A: A lighter sprocket, typically aluminum, reduces rotational mass. This can make the throttle feel slightly crisper and improve acceleration, though durability is less than steel.
