Replace a stretched or broken drive chain with this Universal Parts #25H Drive Chain for the Razor E300 electric scooter. Gold/brass-toned roller chain with "25-H" stamped on the outer plates. Pre-made closed loop � no chain tool or master link required, just route and tension. 47 outer links.
The #25H designation indicates a heavy-duty variant of the standard #25 chain: thicker side plates provide better resistance to shock loads, heavy wear, and continuous operation � important for the higher-torque demands of electric scooter drivetrains.
