Understanding the Correct Battery Size
The Yamaha YFZ 450 typically uses a battery size that fits snugly into its battery compartment without any modifications.

- AGM (Absorbed Glass Mat): A subtype of SLA, known for better vibration resistance and longer life.
- Lithium-Ion: Lighter and longer-lasting but more expensive. If you want to reduce weight, this could be an option, but make sure the size and terminals match.
My Tips on Buying and Replacing the Battery
- Check Dimensions: Before buying, compare the battery’s length, width, and height with your old battery to ensure a perfect fit.
- Terminal Position: Make sure the positive and negative terminals are positioned correctly to avoid cable stress.
