New for 2023, the Sur-Ron Ultra Bee is the third motorcycle to be launched by this highly innovative, market leading manufacturer of off-road motorcycles.
Weighing just 85 kg (inc. battery) the Ultra Bee sits between the hugely popular LBX and the much larger Storm motocross model. The Ultra Bee delivers 12.5kW of peak power and a staggering 440Nm of torque from its 4th generation, permanent magnet motor. Power is courtesy of a 74 Volt, 4kW battery which provides a nominal range of over 40 off-road miles and up to 50 miles in slow-speed, urban settings.
The increased power sees 30 mph come up in just 2.3s, with 50 mph arriving just three seconds later, which is close to the Ultra’s top speed of 56 mph. Keeping this performance in check is SRTC (Sur-Ron Traction Control system), which operates across the bike’s three riding modes to maintain superb stability over all surfaces. There’s also a reverse gear to help deal with those moments when moving forward is no longer an option.
Suspension gets a huge upgrade from the units fitted to the LBX, with fully adjustable 37mm front forks providing 240mm of travel and the same 240mm of travel from the 85mm rear suspension unit. Evenly matched front and rear brakes get heavy duty, twin piston hydraulic callipers which grip 240mm discs.
The powerful, 1kW charger delivers a full charge in just four hours and can be stored under the Ultra’s seat, so that it’s always on hand when needed.
As with other Sur-Ron models, LED lighting is provided throughout and a USB socket is located near the headstock.
An onboard GPS and Cellular unit can communicate with the Sur-Ron IoV (Internet of Vehicles) app that’s due for launch during 2023.
As with the other Sur-Ron models, the Ultra Bee will be available as an off-road or a road-legal bike. Both models have a 100 kg carrying capacity whilst the road-legal Trial Edition has rear footpegs and can accommodate a pillion.
