Check out the new XR. They have I know someone with two pierbon bikes. One very good and one ok. I keep trying to buy one....
sorry, hadn't woken up - it's the 2 cylinder Pani which makes the frame replacement even more impressive.
They are surprisingly not that expensive, I am in the process of ordering a rear subframe for my 998. Cheaper than some of the monkeys are asking for second hand stuff!
Hmm not so sure..priced up a X80R full kit. That wasnt cheap. https://www.pierobonframes.com/en/bikes/pierobon-x80r/
