In a permanently engaged starter system (20), a one-way clutch (40) is located between a starter motor (21) and a starter gear (54) for initiating the start of an internal combustion engine. The clutch (40) can include a starter gear (54), an outer race (56), an inner race (60), a roller cage (42) supporting a plurality of roller disks (46), and at least one spring (52). The roller cage (42) can include an enlarged inertia ring supported adjacent to a radially outwardly located peripheral edge (50) for retarding rotational movement of the roller cage (42) relative to the inner race (60) in response to acceleration of the starter motor (21). The spring (52) biases the roller cage (42) relative to the inner race (60) toward a disengaged clutch position, such that the plurality of roller disks (46) engage the inner race (60) and are spaced from the outer race surface (56).
