Reedy Sonic 544 Ceramic Bearing Set

The Reedy Sonic 544 Mach 2 ceramic bearing set upgrades Reedy's Sonic 540 Mach 2 motor line with ceramic ball bearings for reduced friction and smoother, more efficient rotation than standard steel bearings. Ceramic bearings run cooler and spin more freely under load, which can translate to marginally more power and RPM at the track along with reduced wear over time compared to conventional steel bearing sets. This set is sold as a pair, matching the two-bearing layout used in Sonic 540 Mach 2 motors, and is a genuine Reedy replacement part manufactured to fit precisely in place of the factory-installed bearings. Upgrading to ceramic bearings is one of the simplest ways to unlock a bit of extra performance from an existing motor without a full rebuild or replacement, and it's a popular choice among racers looking for every possible edge. Whether you're refreshing a well-used motor or upgrading a newer one straight out of the box, this bearing set is an easy, affordable way to keep your Sonic 540 Mach 2 spinning smoothly and performing consistently, run after run.
