Yamaha Aerox 155 Version S
The Yamaha Aerox 155 Version S is the top variant of Yamaha's premium maxi-scooter, powered by the same 155cc liquid-cooled engine that produces 14.8 hp. The engine is derived from the Yamaha R15, offering strong performance for both city rides and highway cruising.
One of the biggest highlights of the Aerox 155 Version S is its Smart Key system with an answer-back function and immobiliser, allowing keyless operation. It also comes equipped with Traction Control and Single-Channel ABS, enhancing rider confidence on different road conditions. This Yamaha scooter also features large alloy wheels and a revised suspension setup that is better suited to Indian roads. While the engine and core performance remain unchanged, the added convenience and premium features make the Version S the most feature-rich and expensive Aerox variant.
