D028 is listed for S4R '04-'07 on this list:-

Also lists S2R '06 - '07 and also Monster 800 from '05 to '07

So maybe the D023 is for the earlier S2R before '06? I wasn't aware of any differences for the years on those but who knows.

The D033 that I had was also listed for Ducati Monster S2R 1000 (07), S2R (07) S4R (04-07), S4RS(2007) here: -

Talk about confusing!
