ALLOY ART Swingarm - The Swinger SA08

If you're building a high-performance motorcycle that demands precision engineering and lightweight construction, the ALLOY ART Swingarm SA08 delivers both—without compromise. This three-piece CNC-machined design combines bolted, pinned, and welded construction for the rigidity you need in aggressive riding, while shedding 7 lbs compared to stock. Built for custom builds where every component matters, the Swinger SA08 accepts your existing pivot hardware while offering adjustable shock mounts and a robust 25 mm chromoly axle for serious power transfer.

Be aware: this is a purpose-built custom part requiring fabrication knowledge. You'll need a custom rear brake caliper and bracket, a compatible 25 mm axle wheel, and—if running chain drive—a custom chain slider to protect the arm from wear. Not a bolt-and-forget upgrade, but a foundation for a truly dialed machine.
