- Surron Ultra Bee
Description
The stock jackshaft sprocket on the Surron Ultra Bee wears fast under hard riding — this Warp 9 replacement is hardened tool steel with a black oxide finish so it holds up to real trail and track abuse, and it ships with a fresh jackshaft seal already installed so you're not sourcing a separate part. Warp 9 builds this to the exact OEM bolt pattern and tooth profile, so it's a drop-in swap with no adapter or spacer required.
Compatible With:
- Surron Ultra Bee
Features:
- Hardened tool steel construction for long service life
- Black oxide coating resists corrosion
- New jackshaft seal included and pre-installed in the sprocket
- 13-tooth option matches stock (OEM) gearing
- 14-tooth option adds top speed and extends range by lowering RPM, at a cost of low-end torque
- Direct OEM bolt pattern, no spacers needed
Whether you're chasing more top end or just replacing a worn-out OEM sprocket, this is a straightforward, direct-fit upgrade that most riders can install in under 30 minutes with basic hand tools. Keep the stock 13-tooth sprocket in your spare parts bin as a backup once you've committed to the 14-tooth setup, in case you want to switch gearing back for a specific ride. Ships fast from the USA, straight to your door.

Frequently Asked Questions
Is this compatible with the Surron Ultra Bee only?
Yes, this jackshaft sprocket is purpose-built for the Surron Ultra Bee's drivetrain.
Should I pick the 13-tooth or 14-tooth option?
13-tooth matches stock gearing and torque feel. 14-tooth trades some low-end torque for more top speed and extended range at lower RPM.
Do I need to buy a seal separately?
No — a new jackshaft seal comes included and is already installed in the sprocket, so it's ready to bolt on.
