The 3RACING MIF-011 Ball Bearing Set offers a direct way to reduce rotational friction on Kyosho Mini Inferno ST and ACME NB16 Racing models. The eight-piece set replaces standard bushes to give steadier rotation and less component stress.
By lowering friction in axle and shaft interfaces, these ball bearings deliver crisper throttle response and more consistent handling. That can make a real difference at club races and track days where control matters.
Fitting the 3RACING bearings usually involves removing the factory bushings and pressing the new bearings into place. Their compatibility across Mini Inferno variants makes them a practical upgrade for multiple cars.
