There are so many comments, bro, but unfortunately building a prototype motorbike is not as easy as typing in the comments column. It takes money and a long time, you can see KTM and Aprilia
Interesting if it does happen, anything is possible. Kawasaki used to be in MotoGP but they came out in 2008 if I wasn't mistaken. It seems that the contract this time is different, because of Dorna's experience from the Kawasaki case. According to the source I read that Dorna currently provides subsidies greater than Tim spends so they assume if the cost issue is unreasonable. So far there has been no official statement from Suzuki, let's wait.
