LiveWire’s 125cc-equivalent electric fun bikes begin revealing their secrets

We’re finally starting to learn more about LiveWire’s upcoming S4 Honcho electric motorcycles as the company begins showing off pre-production prototypes around the US ahead of launch.

The bikes were originally expected to arrive in spring 2026 after first being unveiled at EICMA last year, but the latest reports from recent motorcycle shows now point to a summer rollout instead.

Even with some lingering unanswered questions, the S4 Honcho mini-moto is shaping up to be one of LiveWire’s most interesting products yet.

The company is preparing two versions of the bike: the street-legal S4 Honcho Street and the off-road-focused S4 Honcho Trail. Both are built around LiveWire’s new S4 platform and are aimed at the increasingly popular lightweight “fun bike” category that has exploded in recent years thanks to bikes like Honda’s Grom and, perhaps more importantly, a wave of lightweight electric minibikes.
