2025 Ascend Defender 300 Technical Analysis & Specification Breakdown

At the heart of the 2025 Ascend Defender 300 scooter motorcycle, Ascend pairs a 276 cc (16.8 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing.

On the scales, the Defender 300 measures 204.1 kg (450 lbs) dry.
