Ive very nearly finished a project bike (fzr400) to put on the road until guess what, it failed its MOT on the break discs, easy to change yep! but easy to find a pair of front break discs to fit my bike, no!

So basically my question is this.
Does anyone know where id be able to pick up a pair of 280mm diameter dished break discs for this model as the genuine yamaha part costs £300 each!

Ive scoured high and low and not had much luck, ive checked out the brembo website as they have a pretty good catalogue system but theres no match of front discs for my model.
Any help would be very much appreciated.
Thanks, Matt
