Why We Love It

Road-Legal 8mph Performance in a Compact Frame

This 2024 Sterling S425 in Grey brings genuine 8mph road-legal capability without the bulk of a full-size pavement cruiser. Class 3 certification means you can tackle dual carriageways and longer journeys, while the compact 54-inch length keeps manoeuvrability sharp around town. With 26 miles of range from its 50Ah SLA batteries and 500W motor, this refurbished S425 is ready for Hull commutes, countryside lanes, or anything in between.

All-Weather Visibility and Safety Kit

Road-legal scooters demand proper lighting—this Sterling delivers. You get headlights, indicators, brake lights, and hazard lights as standard, plus dual mirrors for confident lane positioning. The electromagnetic and handbrake combo offers precise stopping power, while pneumatic tyres and all-round adjustable suspension soak up potholes and kerb drops. Whether you're navigating East Yorkshire's B-roads or Hull's city-centre traffic, you'll ride visible and in control.

Generous Weight Capacity, Solid Build Quality

Rated to 23 stone (146kg) and tackling gradients up to 8°, the S425 punches above its compact footprint. HMC's engineers have scored the body panels and seat upholstery at 3/5 (honest everyday wear for a used machine), while tyres, wheels, batteries, and electrics all rate 4/5—meaning the mechanicals that matter are fighting fit. A front basket and spare key complete the practical package.

Why This S425 from HMC?

Unlike high-street dealers reselling manufacturer blurb, HMC's Hull workshop has stripped, tested, and refurbished this scooter in-house. You're buying local expertise, not a box-fresh spec sheet copied from the internet. Every used Sterling leaves with a 12-month HMC warranty, a month's free Mark Bates insurance, and free UK-wide delivery by our own driver team. Collection and test rides welcome at our Hull showroom—no pressure, just honest advice from a family-run business that's been serving East Yorkshire for years.
