Built for Serious Ultra Bee Performance

The KyVex fully billet aluminum swing arm is designed for Surron Ultra Bee riders who demand more strength and precision than the factory cast swing arm can provide. CNC-machined in the USA from solid 6061 billet aluminum, it creates a rigid and dependable foundation for aggressive riding, added power, and demanding off-road conditions.

The factory cast aluminum swing arm can flex, warp, or develop cracks over time, particularly on bikes exposed to hard impacts, increased power, and heavier performance upgrades. KyVex replaces that cast construction with a precision-machined billet structure designed to resist those common failure points and deliver long-term durability.

This is a true direct replacement for the original Ultra Bee swing arm. Every mounting point is machined to factory specifications, allowing the stock components to transfer directly onto the new swing arm without modification. The result is a serious structural upgrade that maintains factory fitment while giving the rear of the bike the strength needed for harder riding.

KyVex offers the swing arm in six premium colors, along with custom powder coat options for riders creating a one-of-a-kind build. It is equally at home on a race-focused Ultra Bee, a high-power street setup, or a fully customized show bike.
