The RFLOXA RAF55RV is a premium rear shock upgrade engineered specifically for the Sur-Ron Ultra Bee. Designed around Ultra Bee geometry and linkage ratios, this is not a universal shock — it’s built to deliver proper ride height, balance, and rear-end control for aggressive riders.
Featuring an external nitrogen reservoir, oil/gas separated damping structure, and full multi-stage adjustability, the RAF55RV transforms how your Ultra Bee handles under acceleration, braking, and hard landings.
If you're serious about Ultra Bee suspension mods, this rear shock upgrade is a major performance step forward.
