Swingarm (rear suspension arm) for Street and Storm 125–150. It connects the rear wheel to the frame and lets the suspension absorb bumps.
Replace it after deformation from an impact or a fall, if play has appeared in the bushings, or if the wheel sits crooked. When replacing, check the silent blocks, the axle and the chain tension. When disassembling, also check the axles, bushings and fasteners: worn neighboring parts will quickly ruin the new ones.
