Kumi sends her latest Systema product announcement... "Our newest product is aptly named, as the contents of this kit will certainly be a 'Challenge'. The primary additions to the conventional process are focused on both the Planetary Gear Box and the 7511 Type Motor. By assembling this yourself, you can be confident in being able to maintain it.

The P.T.W. is a form of a collective of custom parts. However, what makes or breaks the performance of this technology is the person who assembles this product.

For those who may have thought that the conventional kit was a little short on expectations as well as those mechanics with confidence in assembling, and for the hard core P.T.W. maniacs this challenge will surely not disappoint."
