Throttle
Smooth off the bottom, so you can crawl a rock garden without the bike lurching. Then it pulls hard when you ask.

Power
24.5kW and about 384 ft-lb at the rear wheel. That's 0–31 mph in under two seconds.
Battery
74V 60Ah and removable. Swap in a spare and keep riding while the first one charges.
Wheel Set
Off-road wheels and knobby tires straight from the crate. Plenty of owners later fit a 21" front for sharper steering.
Suspension
Long travel front and rear, built for faster riding and bigger hits than a Light Bee can take.
Braking
Hydraulic brakes with strong, predictable bite. Reviewers often call the Ultra Bee's brakes a highlight.
THE NEW HP
24.5kW. Built to Push Harder.
The HP X is the Ultra Bee for riders who've ridden one and wanted more. Sur-Ron raised the output, strengthened the primary drive and kept the weight in check. It still sits between a Light Bee and a full-size motocross bike, just with a lot more shove.
BUY ULTRA BEE HP XIs the Ultra Bee HP X Right for You?
Get it if:
you're an adult rider around 5'8" or taller, you've outgrown a Light Bee, you ride single-track, desert or private land, and you like the idea of a bike you can keep upgrading.
Look elsewhere if:
you need it street-equipped (see the Ultra Bee HP T), the rider is small or new to dirt bikes (try the Light Bee X or Hyper Bee), or you want to race full-size motocross against 450s.

How fast is the Ultra Bee HP X?
Top speed is 59 mph, and 0–31 mph takes about 1.84 seconds.
How much does it weigh?
About 195 lb ready to ride. That's roughly 50 lb more than a Light Bee 2 X and far lighter than a gas 250.
What's the real-world range?
Up to about 71 miles at 31 mph in Sur-Ron's test. On hard trail, plan for much less, and carry a spare battery if you ride all day.
Should I get the HP X or the HP T?
