I blew the topend on my 125sx and trashed the cylinder. My dealer graciously loaned me what he called a KTM 174sx. I rode it today and want to do the same to my bike because that thing rips. All I know is that there is a spacer under the jug and obviously has a different cylinder on it. I had one guy tell me that a 174 is a 125 with a 200 cylinder on it but surely there's more to it than that. Is anyone familiar with this setup?
