I have just measured my rear disc thickness 3.6mm oops, has anyone got any good recommendations for a replacement or is it just a case of £100 at motor works?
My only advice would be to measure your current discs and then make sure what you're ordering states the size as there are several diameter options available for the same model of bike even in the same year, it would appear. DAMHIK
I would also recommend the Grimeca discs from Motobins - £87 inc vat for rear disc.
I now have Grimeca discs on front and rear now. They are identical to OEM parts.
