    XS650 v XS650 Special

    Hi, everyone. I'm brand new to the site and to the XS650. I've just bought a 1981 XS 650 special as a winter restoration project. Can anyone tell me if the 650 and the 650 special frames are identical. I prefer the "normal" XS 650 and would consider changing the tank, seat and bars if it is...
