I cannot comment on the use of KTM ergo seat, but it is not right to buy something from Ktmtwins. I ordered this saddle on about 19 june 2021, I received the product with UPS cargo on 8 July 2021, but when I opened the box, I saw that the saddle was broken in the middle, I immediately sent an email to Ktmtwins explaining and showing the situation, Ktmtwins send an email and an apology and as soon as possible, a reply that it would be sent again in a short time.Although I asked many times, 2 months passed and they still did not send the intact product. They informed me that they are waiting for the latest 13 novemver 2021 products, I know that they will say 13 December 21 on that date. They have postponed it to a future date at least 6 times so far. I have given up hope now, I think they will never send it.
