Sprocket Hub Carrier - 54mm Inner Bore for Scooters & Mopeds

Sprocket Hub Carrier for Mini Dirt Bikes and Pocket Bikes

This sprocket hub carrier can stand in for worn or broken parts on small dirt bikes and pocket bikes. Its bore measures 54mm, so it works with a range of setups. Four cush drive rubber pads soften the impact of the chain, which eases strain on the drivetrain. It is one of the scooter chains & sprockets options that can help your ride run smoother and last longer.

Build and Layout

The carrier is cast from alloy, so it is made to handle rough off-road use. Four rubber cushions sit on the sprocket side and reduce the force of the chain. A 6203-RS sealed bearing and a heavy-duty grease seal come fitted, helping keep dirt and water out for dependable performance over time.

Installation and Fit

On the rim side, the carrier uses four bolts and has a raised center area, which makes it simple to mount. It suits a variety of small dirt bikes and electric models that take a sprocket with a 54mm center diameter and 70mm bolt spacing.
