The “Electric Grom” Era Begins: Harley’s LiveWire Unveils S4 Honcho Mini Bikes

Harley-Davidson’s electric motorcycle offshoot, LiveWire, has officially entered production for its highly anticipated S4 Honcho lineup. Aimed directly at young riders, motorhome travelers, and urban commuters, these 125cc-equivalent electric mini-motos represent LiveWire’s boldest pivot yet: moving away from expensive full-sized cruisers toward accessible, lightweight playbikes.

Developed in close collaboration with Taiwanese scooter giant Kymco, the S4 Honcho series launches in two distinct flavors: the off-road Trail and the road-legal Street.

The Lineup: Street Legal vs. Dirt Playground

While both models share the exact same skeletal DNA, they are stripped down and kitted out for entirely different environments.

• S4 Honcho Street (Urban Commuter): Built to take on internal combustion entry-levels like the Honda Grom, the Street comes fully equipped for public roads. It features standard rearview mirrors, complete LED road lighting (headlamp, indicators, and taillight), a license plate holder, and a small circular digital instrument cluster. It rides on tarmac-friendly 12-inch cast wheels and road-biased rubber.

• S4 Honcho Trail (Off-Road Only): This version skips the heavy road gear to prioritize raw, dirt-flinging fun. It ditches the headlight in favor of a clean, vintage-style front number plate and trades road tires for thick, knobby off-road rubber. It features a slightly taller handlebar, raised trail suspension, and increased ground clearance.

Powertrain & Real-World Performance

The real innovation sits right under the flip-up seat. The S4 Honcho is the first-ever LiveWire product to feature swappable, removable batteries—utilizing Kymco’s modular Ionex battery standard. This is a massive win for city apartments or campus students who lack garage charging infrastructure.

• Charging: Pulling power from a standard wall outlet, the dual-pack configuration can replenish from 20% to 80% in approximately two hours.

• The Riding Feel: Rather than utilizing a silent, direct-drive hub motor in the rear wheel, LiveWire opted for a mid-mounted electric motor mated to a traditional chain drive. This preserves a tactile, authentic motorcycle feel and delivers instant, punchy torque off the line.

• Controls: Operating the S4 Honcho feels closer to a modern scooter than a traditional motorcycle. It features handlebar-mounted levers for both the front and rear hydraulic disc brakes, doing away with the foot pedal entirely. It also includes a dedicated electronic reverse gear across both models to make parking and trail-maneuvering effortless.

Pricing and Availability

The S4 Honcho lineup represents the lowest financial barrier to entry in LiveWire’s history. It is slated to land in dealerships internationally later this summer.

While they still command a premium over entry-level petrol alternatives, the combination of a rugged tubular steel frame (which uses the aluminum battery vault as a structural member), low approachable seat heights, and instant electric grunt makes the Honcho an enticing gateway drug for the next generation of riders.
