This motor, made by Sagami Micro for Tamiya, was only released as part of the 49190 rerelease Dyna Storm kit. The motor itself is a "hybrid" with parts from both the Super Stock- and the Acto-Power series.
The can is from the Super Stock giving no adjustability and limited service access. The rotor is from the 53122 Acto-Power pink motor.
Official performance data in general is unknown, as Tamiya never released any.
