2025 Surron Ultra Bee

Midweight Just Got a Whole Lot Meaner The 2025 Surron Ultra Bee HP takes everything riders love about the Ultra Bee and turns up the intensity. Built for riders who want harder acceleration, more range and serious off-road capability, the Ultra Bee HP combines 21kW of Turbo power with a larger 74V 60Ah battery, a redesigned 19/18-inch wheel setup and a chassis engineered to stay composed when the terrain gets rough. With up to 377 ft-lb of wheel torque and a curb weight of just 195 lbs, the Ultra Bee HP delivers the power experienced riders want without stepping up to the bulk of a full-size motorcycle. 21kW at the Push of a Button The second-generation Hairpin motor produces 18kW in Sport Mode and unleashes up to 21kW in Turbo Mode. Hairpin winding technology increases motor efficiency and improves heat dissipation, while the MTPA/MTPV controller provides smooth, precise power delivery across the entire RPM range. The result is instant response when you need it with the control required for technical terrain. More Battery. More Time to Ride. A high-capacity 74V 60Ah lithium-ion battery provides stable power and up to 71.5 miles of manufacturer-tested range at 31 mph. The battery charges from 20–80% in approximately 2.5 hours, giving you more time on the bike and less time waiting for the next ride. Power for Every Type of Terrain Six riding modes let you adapt the Ultra Bee HP to changing conditions: Turbo: Maximum 21kW output Sport: Strong 18kW performance Daily: Smooth, balanced power Eco: Reduced output for longer rides Crawl: Precise control through technical sections Reverse: Low-speed reverse assistance A three-stage adjustable throttle curve lets you further tailor response to your riding style. Serious Traction and Braking Control Surron Traction Control helps manage rear-wheel slip across loose dirt, mud and changing trail conditions. The BERS energy-recovery system provides adjustable regenerative braking, allowing riders to fine-tune deceleration and control without relying entirely on the hydraulic brakes. Redesigned motorcycle-grade brakes provide increased caliper rigidity with a light, linear lever feel for predictable one-finger stopping power. Built to Take the Hit The forged aluminum frame keeps the Ultra Bee HP light and agile while maintaining the strength needed for demanding off-road riding. A completely redesigned suspension system delivers 9.4 inches of usable travel at both wheels. The reinforced gold front fork offers adjustable compression and rebound with increased support deeper in the stroke, while the INTERSECT TR multi-link rear suspension helps maintain traction over rough terrain. The updated 19-inch front and 18-inch rear wheel combination adds rear-tire width for improved grip and stability. Carbon-Core Primary Drive The redesigned primary drive uses a carbon-fiber-core belt with a forged pulley and tungsten-carbide coating. This system provides greater load capacity, improved wear resistance and stronger power transfer to handle the Ultra Bee HP’s increased output.
