BREMBO Front Brake Cylinder, 13 mm piston diameter, banjo bolt thread M10x1.00 (mirror thread clamp Art. 41973 may be required)

Note if used as a replacement for TT600S/E Belgarda: these had an optically identical Brembo brake master cylinder with a 12 mm piston diameter fitted as standard, so this brake pump has a slightly harder pressure point. No road licence or individual approval required/street legal.
