Center Stand Battery Box

CB550/CB500 Center Stand Battery Box — Stainless Steel

The cleanest battery relocation available for your Honda CB550/CB500. Whether you're building a cafe racer, brat style bike, tracker, scrambler, or any custom vintage Japanese motorcycle, this precision-built stainless steel battery box mounts in the space where the OEM center stand once lived — the lowest, most hidden position on the entire frame. Once installed, your battery simply disappears.

Nothing kills the lines of a stripped-down build like a battery hanging in the frame triangle. This box solves it for good — leaving that open-frame look every cafe and brat builder is chasing.

Designed around the Antigravity 8-Cell battery, the box also accommodates other batteries of similar dimensions, giving you flexibility in your electrical layout.

Built like a proper part, not a bracket:

1. Brushed stainless steel construction — no paint, no rust, no maintenance
2. Custom CNC-machined shouldered spacers, engraved with the Thirteen Motorcycles logo, that locate the box precisely and make installation straightforward
3. Complete hardware kit included — stainless studs, washers, and nylon lock nuts. Nothing extra to source.
4. Purpose-designed fitment for CB550/CB500 frames

Fitment Beyond the CB550/CB500:

While this box was designed specifically around the CB550/CB500 center stand mounts, it may also work on other vintage Honda models with similar frame architecture, such as the CB750. If you're building something else and think this could work for your frame, reach out with your measurements — we're happy to help you figure out fitment before you order.

Installation Notes:

This kit is built for the hands-on builder. Installation requires bending the existing center stand mounts open to slide the mounting studs through, and cutting the OEM center stand spring mount. From there, the shouldered spacers do the work — everything locates, seats, and torques down clean.

Whatever you're building — cafe racer, brat, tracker, or full custom — this is the professional solution for tucking your electrical away where nobody will ever look. Because the best battery placement is the one nobody can find.
