# CFMoto 800NK Sprocket Guide: Choosing the Right Size & Ratio for Performance
Unlocking the full potential of your CFMoto 800NK often starts with a component many riders overlook: the sprocket. Changing your final drive gearing is one of the most effective and affordable ways to transform your bike’s character. This guide will help you choose the perfect **cfmoto 800nk sprocket** setup for your riding style.
## **Understanding Sprocket Size and Gear Ratio**
The relationship between your front (countershaft) and rear sprocket sizes determines your final drive ratio. This ratio directly controls how engine power is delivered to the rear wheel.
* **Stock Gearing:** The factory setup offers a balanced compromise for general street use.
* **Lower Gearing (More Acceleration):** Installing a larger rear sprocket or a smaller front sprocket creates a lower (shorter) ratio. This gives you quicker acceleration and more responsive low-end power, ideal for city riding or technical roads.
* **Higher Gearing (More Top Speed):** A smaller rear sprocket or larger front sprocket creates a higher (taller) ratio. This can increase top speed and reduce engine RPM at cruising speeds, potentially improving fuel economy on highways.
### **Performance Impact of Sprocket Changes**
**
Acceleration vs. Top Speed Trade-off
**
Every change is a trade-off. Significantly lower gearing will reduce your theoretical top speed and may increase engine strain at high RPMs. Conversely, higher gearing might make the bike feel sluggish when accelerating.
**
Chain Life and Maintenance
**
Major sprocket size changes often require a new, longer (or shorter) chain. Always replace the chain and both sprockets as a set to prevent premature wear. A mismatched, worn set is a safety hazard.
## **How to Choose the Right Sprocket for Your 800NK**
Your choice should be driven by how and where you ride most often.
* **For City & Aggressive Street Riding:** Opt for lower gearing (e.g., +1 or +2 teeth on the rear). This makes the bike feel livelier and improves pull out of corners.
* **For Highway Touring & Commuting:** Consider stock or slightly higher gearing (-1 tooth on the rear) for more relaxed cruising.
* **For Track Use:** Riders often fine-tune gearing for specific tracks. Lower gearing is common to maximize drive out of corners.

Material Considerations: Steel vs. Aluminum
**
Steel sprockets are immensely durable and offer the longest lifespan. Aluminum sprockets are lighter, reducing unsprung weight for potentially better suspension response, but they wear faster. For most street riders, steel is the practical choice.
When you’re ready to explore your options, you can find a quality selection of compatible **cfmoto 800nk sprocket** kits and chains to complete your upgrade.
## **Frequently Asked Questions (FAQ)**
**
Q: How many teeth are on the stock CFMoto 800NK sprockets?
**
A: Consult your owner’s manual for the exact stock specification, as it can vary by model year. This is your essential baseline before making any changes.
**
Q: Can I change just the front or rear sprocket?
**
A: You can, but it’s not recommended for long-term health of your drive system. For optimal performance and longevity, always replace the chain, front sprocket, and rear sprocket as a complete set.
