New genuine Brembo 9mm clutch master cylinder. Fits KTM, Husqvarna, GasGas, Beta, Sherco and TM models that use a Brembo hydraulic clutch. The Brembo 9mm master cylinder has a much lighter and easier pull than the 10mm master cylinder, which comes stock on most dirt bikes with a Brembo clutch. This is the best mod you can do to lighten your clutch pull. Please message if you are unsure about fitment.
