An 800 SXR bottom end is slightly different than a 750 bottom end, however a 800SXR cylinder will bolt up directly to a 750sx bottom end. I wouldn’t recommend doing this if you using a 750 bottom end with a small pin crank (750SX). If you have a 750SXI bottom end with big pin crank it will work fine. I put a 2003 SXR800 on my 1995 SXI bottom end and rode it for 2 years with no problems.
