I'll update this for any cheapskate's like myself. This is a pretty universal starter for most ducati and many other European bikes.
DENSO DUCATI P/N:
27040051A
DENSO P/N:
428000-1070
AFTERMARKET P/N:
SM9162
RPELACEMENT BRUSH SET:
SMBK175
The aftermarket and replacement brush set were listed by a UK company called electrex world Ltd. Brushes are about $27.00
Replacement starter is about $125.00, no idea who makes it, but these part numbers show up on other sites, so they may be from a manufacturer, or they may be electrex part numbers. If anyone is very handy the brush size is 6x9x12.5 and can be purchased in a set of two brushes for denso starters, these would need to be crimped/welded onto the power terminal and brush plate. The above brush part number comes assembled on the terminal and plate with Springs. Hope this will help someone, as this is an easy repair that will save someone 600 or so bucks over a new denso ducati starter.
