R46 Rear Shock
EXCEPTIONAL RESPONSIVENESS
Ultimate Suspension Tuning
Fully tunable valving on compression and rebound, with spring rates matched to rider weight and riding type. Adapt your suspension setup for different types of rides,
enhancing overall riding experience.
TUNING WITHOUT COMPROMISE
LSC (Low Speed Compression)
Superior pressure balance and frequency response providing the ultimate overall responsiveness and performance for riders.
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)
Made For You
Tunable to any rider style and condition. Personalize to rider weight up to 300 lbs (135
kg) with high-tensile steel spring rate options.
BUILT TO LAST
High Durability Finishing
Type 3 hard anodized body cap, body, reservoir, end cap, spring hardware, and clevis.
Induction heat treated, hard chrome hollow shaft. The rear shock will look new, even
after thousands of miles.
Extremely Easy to Rebuild
Fully serviceable design ensures easy rebuilds and custom tuning.
Direct Swap
Easy installation, 320 mm length (85 mm stroke) bolts directly onto a stock Ultra Bee.
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.
NOTE: Some aftermarket triangles may have significant interference that could damage the shock and/or triangle. Do not install the Sirris shock if any interference is detected!
Lightweight
Weighs only 3.9 lbs (1.76 kg) plus spring.

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.
