Introducing the KyVex fully billet aluminum swing arm designed specifically for the Surron Ultra Bee. Built for riders who push their bikes harder than the stock swing arm was ever meant to handle, this swing arm is CNC-machined from solid 6061 billet aluminum to deliver unmatched strength, precision, and durability.
The factory cast aluminum swing arm is known to crack, flex, and warp over time — especially under aggressive riding, heavy upgrades, or hard off-road use. Our billet swing arm eliminates those weaknesses entirely by replacing the cast construction with a precision-machined structure engineered for maximum strength and long-term reliability.
This is a true direct replacement for the stock swing arm. Every mounting point is precisely machined to factory specifications, so all OEM components bolt directly on with no modification required. Simply transfer your existing parts and upgrade to a swing arm that's built to handle serious power and real-world abuse.
To match your build style, the swing arm is available in six premium colors, along with custom powder coat options for riders who want a one-of-a-kind look. Whether you're building a race bike, a high-power street setup, or a fully customized show build, this swing arm gives you the strength and the style to match.
