The Minato-Seat is for shure heavier and should not be compared to any regular Pivotal Seat on the market.
Because it offers more Material to be lasting and strong enough.
It also is really great to handle in the back.
After over 20 Years of using Primo Steroid-Seats i finally have found a working alternative with the Minato Seat for me. It is also a great alternative to the KHE / Infinity / Autum rail-plastic seats.
Great Job ARES, Thank you!
