With the announcement of the Code Name: "KUMI" Motor from Systema Engineering which is the newest and greatest motor release for use with the PTW series, they further give us an update that there will be two types of motors that will be released under this code name which uses the name of the CEO of Systema. She has full faith that this motor series will resolve the issue(s) plaguing the old PTW motors.

There are two versions of our new motor.
 One resembles the 7511 type motor: "Code name KUMI 7511 Type".
The other, which is one of the more popular motor types for the P.T.W. line, based on the 490 type motor: "Code name KUMI 490 Type".


You may have already noticed, that the difference between the two motors is simply in the outer appearance and not in performance.
Future orders of the P.T.W. as well as Challenge Kits will all include the "Code name KUMI 7511 Type" motor.
 For those who have the 2012 model P.T.W. (and prior), may purchase the "Code name KUMI 490 Type" motor; and will be able to enjoy the performance of the new motor without having to purchase a new grip!
