Things like alternators are pretty generic on bikes,
www.electrexworld.co.uk list it as a type g17 stator to fit the following,
HONDA:
NSR250, Bros 400 (NC25), CB1-400 (NC27), CBR400 (NC29), CBR400RR (NC23)*, VFR400 (NC24)*
ATV-PILOT
YAMAHA:
TZR250V
Their are probably loads more bikes that use this stator, just cross referance some of the above with your local bike shop, I'm sure you'll find something pattern/after market cheap enough,
