Ultimate Guide to CFMOTO MT450 Motorcycle Sprocket: Performance & Replacement

Your CFMOTO MT450 is built for adventure, but its true performance potential is unlocked by a single, often overlooked component: the sprocket. This guide dives deep into everything you need to know about the CFMOTO MT450 motorcycle sprocket, from how it impacts your ride to choosing the perfect replacement.

Understanding Sprocket Function and Impact

The sprocket, working in tandem with the chain, is the final link in your motorcycle’s drivetrain. It translates engine power into rear wheel movement. Changing your sprocket size is one of the most effective and affordable ways to modify your MT450’s character.

Gearing Ratios and Performance Tuning

Altering the number of teeth on your front (countershaft) or rear sprocket changes the final drive ratio. A smaller front or larger rear sprocket lowers the gearing, providing quicker acceleration and better hill-climbing power—ideal for technical off-road sections. Conversely, a larger front or smaller rear sprocket raises the gearing, increasing top speed and reducing engine RPM at cruising speeds, perfect for long highway stretches.

Material and Durability Considerations

Sprockets are typically made from steel or aluminum. Steel sprockets, like the durable options available for your cfmoto mt450 motorcycle sprocket, offer exceptional longevity and are the go-to for reliability. Aluminum sprockets are lighter, reducing unsprung weight for slightly improved suspension response, but they wear faster.

When and How to Replace Your Sprocket

Always replace your sprockets and chain as a set. A worn sprocket will rapidly destroy a new chain, and vice-versa. Look for hooked or shark-fin-shaped teeth on the sprocket, which indicate severe wear.

Step-by-Step Replacement Guide

Replacement requires basic tools: sockets, a torque wrench, and a chain tool or breaker. First, secure the bike and remove the rear wheel. Loosen the front sprocket nut (while holding the rear brake), then remove the old sprockets. Install the new ones, ensuring the rear sprocket bolts are torqued to specification. Always fit a new master link or rivet the chain correctly for safety.

Frequently Asked Questions (FAQ)

Q: What is the stock sprocket size for the CFMOTO MT450?

A: The MT450 typically comes with a 14-tooth front and a 48-tooth rear sprocket. Always double-check your owner’s manual for exact specifications.

Q: How often should I replace my sprockets?

A: There’s no fixed mileage. Inspect them whenever you clean and lubricate your chain. They usually need replacement every 1-2 chain cycles.

Q: Can I change just one sprocket?

A: It is highly recommended to replace both sprockets and the chain as a complete set to ensure even wear, optimal performance, and safety.
