#428 3' Roller Chain for Scooters & Mopeds

3' Roller Chain for Scooters and Mopeds

This three-foot roller chain suits a range of machines, including scooters, mopeds, ATVs, dirt bikes, super pocket bikes, karts, and buggies. It works as a dependable replacement part that carries power through the drivetrain. Mechanics often swap it out during routine upkeep, alongside other scooter variators & roller weights, to keep the vehicle running smoothly.

Construction and Specifications

The chain has a 12.70mm pitch and an 8.51mm roller diameter, so it fits several small engine vehicles. Its width between the inner plates is 7.75mm, with a 4.45mm pin diameter, a 16.70mm (L) and 18.2mm (Lc) pin length, and an 11.80mm inner plate depth. Each plate is 1.60mm thick. Rated at 18.0 kN tensile strength and 20.1 kN average tensile strength, it is designed to withstand heavy loads and wear.

Installation and Maintenance

Fitting a new roller chain is simple for anyone comfortable with scooter mechanics. The old chain comes off, the new one goes on in the same position, and alignment and tension should be checked as you go. Inspecting the chain regularly helps delay early wear and keeps the drivetrain performing well.
