KKE Rear Shock Upgrade for Surron Ultra Bee

The KKE Rear Shock Upgrade is a full-feature rear suspension system designed specifically for the 2023–2025 Surron Ultra Bee. Engineered for performance, adjustability, and durability, this shock delivers better damping control, increased support, and smoother performance across all terrain types—from singletrack to urban freeride to MX-style jumps.

With a 40mm large-bore cylinder, high- and low-speed compression adjusters, and a professionally tuned oil channel layout, this rear shock is built to meet the demands of aggressive riding while offering fine-tuned control and comfort. The spring preload is set at 500 lbs, ideal for most riders in the 65–85 kg weight range, and capable of handling 90% of terrain scenarios via clicker adjustments.
