motorcycle alarm system,

This is the sister listing to the last one: the NS Products (New Star Autos) motorcycle alarm system, model NO'785. It's the same brand and the same feature list as the NO'786, in a blue box instead of the gold one.

What's different from the NO'786:

Packaging: blue box with a "Best Quality Accessories" badge, versus the gold box
Remotes: a metal-look key-fob remote and a flip-key style remote, instead of the flip-display remote shown on the 786
Extra in the tray: a small battery (looks like a 9V-style or similar cell) sits beside the siren, which the 786 graphic doesn't show

Same on both:

Wiring kit, relay, siren, main unit and two remotes
Anti-theft protection, loud alarm, remote control, shock sensor, disconnect protection and universal fitment

Things to check before selling or fitting:

Confirm the contents match the graphic. Ad images like this look partly rendered or edited, so open a sample box to check the remotes, relay and battery are really what's pictured.
Voltage: make sure it suits the bike (12V vs 6V).
Remote batteries: check what the remotes take and whether spares come in the box.
Wiring: it needs a fuse and correct ignition/starter connections through the relay.

If you're sorting your stock, the practical difference is that 785 and 786 are two box styles and remote designs of essentially the same kit, so label them clearly so customers get the remote they expect. Are you preparing a catalog, or comparing the two for pricing?
