Detailed description

The Sterling S425 is built as a comfortable, practical road scooter with thoughtful control features. The steering uses a delta handlebar paired with a wig‑wag control system, so you can drive using either thumbs or fingers. An infinitely adjustable tiller lets you set the handle position to suit your reach and posture, and tilting the tiller will adjust the headlight angle automatically for better visibility.

Ride quality is a focus, with all‑round suspension and pneumatic tyres that help the scooter cope with uneven surfaces and small obstacles. The scooter has an increased wheel height, which improves clearance over kerbs and rougher paving, and bright front and rear LED lights support safer use in lower light. There is also ample foot space to help you find a comfortable driving position.

Comfort and transfers are made easier by a luxury adjustable seating system that allows changes to height, depth and recline. The seat rotates to aid getting on and off, while flip‑up armrests can be adjusted for angle, width and depth to suit personal preference. The scooter supports a sturdy maximum user weight of 150 kg, making it suitable for a wide range of users.
