The Bonneville 400 test mule got spotted again -- as a scoop lover, I can't ignore this. If it's built on the Speed 400 platform wearing the Bonneville name, the real story is how they shape its character against the traditional big-displacement Bonneville. I've been restless all the way up to the expected September 2026 launch.

It mentions expected launch in India, but timing for other countries is still unclear.

With a projected September 2026 launch, does that mean an official announcement is still a few months out?

Given how often these spy shots are appearing, I'd say it's already entered the final testing stage.

Bringing the Bonneville name to a small-displacement classic naked makes sense as a brand strategy.

It keeps getting spotted in spy shots, but there's still not much confirmed until the official announcement.

Following the Speed 400 and Scrambler 400 X, another model wearing the Bonneville name — the series is really rounding out.
