USED PARTS DISCLAIMER: This is a used motorcycle part and may show normal signs of age, installation, removal, storage, and previous use, including scratches, scuffs, discoloration, carbon staining, light oxidation, gasket residue, or other cosmetic wear.

FITMENT NOTES: OEM 16593-99 cylinders are commonly used with Harley Twin Cam 88ci and 96ci engines because both use the same 3.75-inch cylinder bore. Exact motorcycle fitment varies by year and engine combination. These are cylinders only, so the buyer must match the proper pistons, rings, wrist-pin configuration, and gaskets for the intended 88ci or 96ci build.
FITMENT: Buyer is responsible for verifying fitment before purchase. Fitment information is provided as a reference based on OEM numbers, casting marks, measured bore size, and published references. Engine parts may have been changed or modified over time. Compare part numbers, bore, piston markings, wrist-pin size, cylinder height, base spigot, and photos with your existing engine components before installation.
