Genuine Brembo rear foot brake master cylinder for the Stark VARG. Premium Brembo build quality for crisp pedal feel and consistent braking pressure. Compatible with all Stark VARG MX, EX and SM. For road-legal models (VARG EX/SM), the brake light switch SEX1-BR-RWF-80 must be installed on the banjo bolt. Not designed for dual-brake setups — excess pressure will damage the master cylinder and is not covered by warranty.
