Gavin - I cant answer your question but I had a good look around my bike while washing it this afternoon.
I bought it in July 05 and understood that it was commonly known as an 06 as it was an ABS model - one of the first in NZ.
Vin is SMTTF6865J6236370.
On the front of the headstock is 080205 which I understand may be the build date.
On the front brake master cylinder is 4T 14.This sounds like a 14mm cylinder.My brakes are fine.
Does this help?
Grant
