Optional DSC note: We're fine tuning the DSC now and it will be available in a couple months (likely early 2025). The DSC will offer a wider adjustment range than the LSC. LSC and DSC fit in the same cavity and are cross compatible (with a rebuild). Both will be offered as service parts. (ie. if you purchase the current LSC now, it can be serviced and tuned to add DSC later. More details to follow)

STOCK ULTRA BEE TRIANGLE FITMENT:
For guaranteed fitment on your Surron Ultra Bee, we highly recommend the Sirris rear triangle installed during the shock installation procedure.
The Sirris Shock is designed to offer the maximum possible piston size and still fit within the stock linkage. Tolerances on each stock Ultra Bee vary. Light contact between spring OD and stock triangle may occur. We highly recommend our higher clearance triangle to prevent this.
WARNING: Some aftermarket triangle links may have significant interference that could damage the shock and/or triangle. It’s important to check clearance as you assemble and cycle the suspension. Do not install Sirris shock if any interference is detected. Failure to properly install the shock with proper triangle can lead to a loss of control of the motorcycle which can result in SERIOUS INJURY OR DEATH.
