Surron Ultra Bee parts guide: every verified part, by system
JUL 2026·12 min read·Fits: SUB (114)

The short version

The Ultra Bee runs a 74V 55Ah pack, a 520-pitch final-drive chain (Warp 9 EK 520 MX, Ultra Bee sprocket in 520) and a belt primary that DirtyBike converts to a 420 chain. Rear sprockets on file: 50T, 52T, 54T, 56T steel from DirtyBike and 54T from JFG. Warp 9's Ultra Bee rotors are 240, 260 and 300 mm. GUTS lists two seat products for the Ultra Bee (2023–26), including the RJ Wing cover with 1-inch knee wings. Only 12 of the 114 Ultra Bee parts also fit the Light Bee X.

Key takeaways
  • 114 verified parts: Warp 9 Racing (45), DirtyBike (41), JFG Racing (26), GUTS Racing (2).
  • 520 final drive, 420 primary. Neither pitch matches the Light Bee's 420 final drive, so sprockets do not swap between the two bikes.
  • Rotors run 240 to 300 mm, with 260 mm and 300 mm brackets sold with or without the rotor.
  • Drivetrain is the biggest system here: 24 parts, most of them primary-drive chains and conversion kits.
  • Tables are lowest price first, 12 rows max; the link under each opens the full filtered collection.

The Ultra Bee shares a badge with the Light Bee and almost nothing else on the parts shelf. This guide lists the 114 products we have verified against it, by system, with today's price and the vendor part number. The drivetrain section is the one to read twice: it holds two different chain pitches on the same bike, and they are not interchangeable. The fitment database carries the same tags per product.

What does not cross over to the Ultra Bee?

The Light Bee X list. 249 of the 261 Light Bee X parts on this store have no Ultra Bee tag. The 12 that do are small shared items: JFG's inner tube and Ultra Bee foot pegs, Warp 9's hub bearing kits, foot peg sliders and screws, bar straps, helmet hook and tow rope, and DirtyBike's kill switches, chain alignment tool and steering head bearing. Everything else in the Light Bee X guide is unverified on the Ultra Bee.

Two pitches on one bike. The final drive is 520 (Warp 9 EK 520 MX Chain, Warp 9 Ultra Bee Sprocket Aluminum in 520). The primary-drive conversions and replacement chains from DirtyBike are 420 (RK MXU, RK MXZ Race and sealed X-ring). A 520 sprocket does not run a 420 chain; match pitch to position.

Rotor brackets. Warp 9's 260 mm and 300 mm Ultra Bee rotors are listed with matching brackets; the 240 mm options are not. Order the bracket with the rotor when you size up.

Questions, answered

What chain does the Surron Ultra Bee use?
The final drive is 520 pitch on this store: Warp 9's EK 520 MX Chain and Ultra Bee Sprocket Aluminum are both listed as 520. The primary drive is a belt from the factory, and DirtyBike's Ultra Bee conversion kits and replacement primary chains are 420 pitch.
What rear sprocket sizes fit the Ultra Bee?
DirtyBike's steel rear sprocket is listed in 50T, 52T, 54T and 56T, JFG lists a 54T, and Warp 9's aluminum Ultra Bee sprocket comes in ten sizes in 520 pitch.
What rotor sizes fit the Ultra Bee?
Warp 9's Ultra Bee rotors are listed at 240 mm (fixed or floating), 260 mm floating and 300 mm floating, with 260 mm and 300 mm brackets sold separately or bundled with the rotor.
Do Light Bee X parts fit the Ultra Bee?
Rarely. Only 12 of the 261 Light Bee X parts carry the Ultra Bee tag. The bikes run different final-drive pitches (420 vs 520), different rotors and different seat patterns.
Which GUTS seat fits the Ultra Bee?
GUTS lists two: the Sur-Ron Ultra Bee seat (covers, complete seats and foam, Ultra Bee 2023–26) and the RJ Wing seat cover with 1-inch foam knee wings and Deep Diamond grip. Build time is 10 to 14 business days for a cover; the RJ Wing in any color other than black is 17 to 24.
How much is shipping on these parts?
Orders over $99 ship free. Under $99, shipping is charged by weight and starts at $7.95. Returns are accepted for 14 days.
