FE390 / KTM EXC(-R) master cylinder swap?

Managed to break both clutch and front brake master cylinders last Sunday. Have sourced a replacement for the clutch (9.5mm bore) but struggling with the front brake.

Anyone know which late model KTM's have a m/cylinder with a 12mm bore? I''ve been offered a couple but the vendors have no idea of bore size and/or what model they're off.

All help appreciated.
 
Hi Possu,

If you are still looking, the MC from any KTM from 125-640 (not supermoto) should work perfectly fine.
 
A 12mm bore size sounds quite large. Most of the KTM MC's are smaller which should provide for more precise, easier braking.
