Title: Front Brake Switch - 2019 Zero SR
Post by: CagivaRider on July 20, 2025, 02:53:21 AM

The front brake switch on my 2019 Zero SR failed. I found a replacement - Moto Guzzi OEM Front Brake Master Cylinder Lever Microswitch for Brembo Masters. It is a perfect fit. It's a standard Brembo brake switch I bought off Ebay for $20.

I suspect it will fit on many of the Gen2 SR/S bikes.

The screws to attach the switch to the the front brake lever use a T6 tool. The mirror/front brake clamp bolts use a 4mm allen.

Looks nearly identical to standard IP67 microswitches like these.

4-7 USD in this store.

To search for local supplier, specify Cherry switch, DC type, AA actuator and QC connectors.  You will be asked if it's DC1, DC2, DC3 or DC4. You can find that on the old switch.
