#40 Roller Chain for 3ft Length & Mini Bikes

#40 Roller Chain for Mini Bikes and Go-Karts

If you are working on a mini bike or go-kart, the #40 Roller Chain provides the strength needed for high-torque setups. This 3-foot run of chain suits a range of projects, from restoring older models to building something custom. It belongs with our mini bike and pocket bike parts, and its job is simple: carrying power from the drive to the wheels.

Built for High Tensile Loads

This chain is made to handle the loads that come with 4-stroke engines and strong electric motors. The design limits stretch so it keeps performing consistently over time. The heavy-duty rollers resist wear and stay properly aligned, even when the work gets demanding.

Ships Pre-Lubricated

The chain comes packed with a generous coating of high-grade lubricant, so it is ready to fit straight out of the box. That lubrication cuts down on friction, letting the links move freely and run more efficiently. It is especially useful for off-road riding or track use.
