Sur Ron custom built 2025

Sur Ron custom built 2025(often referred to as the Ultra Bee HP in many markets and dealer listings for the updated high-performance variant) is the mid-size, do-it-all electric off-road motorcycle in the Sur-Ron lineup. It’s designed as a powerful trail/enduro bike with significant upgrades over earlier versions, including a stronger motor (often called the “Hairpin” type), larger battery capacity in most 2025 configs, improved suspension, faster charging, and added modes like Turbo and adjustable crawl control.
