| A 2001 S should have the SPS motor, but you would need someone like John Hackett to check engine numbers against the Ducati build log to confirm.
However, don't think you are getting a full blown SPS motor, cos you're not. As far as I can remember you only really get the bottom end, Ti rods etc. Fairly certain top end is pretty standard bip with regard to cams etc. |
