Sur-Ron Ultra Bee (2023-2025)
Gearing-up swap (50T vs 53T OEM). Works with the existing 102-link chain in most cases, but chain length may need to be shortened by 1-2 links depending on swingarm position. Mounting hardware included (6 screws). Select color at checkout.
A gearing-up rear sprocket for the Sur-Ron Ultra Bee. At 50 teeth (vs. 53 stock), this changes how the bike accelerates and tops out — and that's the point. With this sprocket installed, your final drive ratio is taller, which means: slightly slower acceleration off the line, but noticeably more top speed and longer pull at higher RPM. The bike feels less aggressive at low speed and more comfortable at sustained higher speeds.
Who this is for: street riders who run at higher speeds, commuters spending time at highway-ish speeds, and trail riders on fast open terrain where the bike feels like it's running out of gear in stock form. If you ride this way and feel like the bike spins out the throttle at high speed, this is the swap that fixes it.
Who this isn't for: technical riders, hill climbers, and anyone riding tight slow off-road. The taller gearing means less mechanical advantage at low speed — you'll feel it as reduced grunt on steep climbs and slow technical sections. If you want OEM behavior in a higher-quality sprocket, get the 53T version instead.
CNC-machined from 7050-T6 aluminum — same aerospace-grade alloy as the 53T sprocket, stronger and lighter than the stock alloy. Available in 5 anodized colors: Black, Gold, Purple, Red, or Blue. Includes 6 mounting screws. Runs with the OEM 102-link chain; you may need to shorten by 1-2 links depending on your swingarm setting.
