Based on the extremely successful Vector X20 Modified Brushless motors, LRP developed special Stock racing motors. Innovative features like the dual axis balanced dynamic rotor, finely adjustable five-step timing or the optimised compact stack for better drive feeling and higher efficiency have been taken over to the X20 StockSpec.
The motors are available in the specific windings for Stock racing. They are extremely powerful, low maintenance and comply to the rules of the international and national Stock classes.
