The stock Sur-Ron LB-X / Segway X260 swingarm is cast, flexible, cracks at pivot under jumps, and too short for 60MPH+ stability. The Upgraded KO CNC Black Swing Arm is full billet 6061-T6 aluminum CNC machined from one block, black anodized hard coat, laser engraved KO CNC + SUR-RON LB-X / SEGWAY X260 – 30% stiffer, 50mm extended wheelbase, pre-installed sealed bearings – direct bolt-on, no mods. Used by factory race teams.
50mm extended = wheelbase goes from 1260mm stock to 1310mm – huge difference: less wheelie on hard throttle, more stable at 60MPH 2025 8000W model, better traction uphill, better cornering exit. Still fits in truck, still wheelies but controlled. Stronger than stock – no more cracked pivot – perfect for jumps, big riders, and high-power controllers (KO FOC, BAC8000).

Why You Need This KO CNC Black Swing Arm?
Problem: Stock cast swingarm flexes at 50MPH+, cracks at pivot with jumps, too short – wheelies too easy, unstable at high speed, chain rubs. Solution: KO CNC billet – no flex, no crack, 50mm longer – stable at 60MPH+ on 2025 8000W, controlled wheelies, better traction, better corner exit. Every serious LB-X rider upgrades this first – after controller and battery. Looks factory but premium – black anodized matches all your black editions (Stealth Black, Outlaw, Joker). If you ride hard, jump, weigh over 80kg, or have KO/BAC controller – this is mandatory.
