Parts and upgrades for the Altis Powersports Sigma MX: brake pads, footpegs, seat covers, rear shocks, brake levers and the universal e-moto range of bars, grips, 520 chains, tires, tubes and maintenance gear. The Sigma MX is the 19/16 wheel version of the Sigma and shares its chassis, motor, battery and 520H chain, so most Sigma parts list both bikes.
