Benefits and Features

Nowadays it’s standard to have a flat L-shaped design.
You can lay it out at right angles to the terminal, making it perfect for reuse.

*This generation has terminals that are bent, so when using modern batteries you need to straighten them.
If that hassle bothers you, try this one!
*The positive terminal side is connected to the main harness, so it can be reused.

The main earth connection side is a lock coupler (standard nowadays).
Kawasaki Z-series bikes use spade terminals as standard. Reusing this improves safety.

At about 350mm long, it can be reused on most bikes.
I often shorten just the crankcase mounting side and crimp it for reuse.

Why use this main earth?
It’s affordable, so you don’t need to source materials separately.
You can buy this earth and make an earth lead with just ring terminals—it’s convenient!
