The HFM.Parts BM57 Master Cylinder features a 17/16 inch (27mm) piston bore size and is suited to both ABS and Non-ABS setups.

Perfect for if you intend to increase your braking performance and reduce that spongy pedal, giving a shorter, firmer pedal.

The product is suited for RHD models specifically, however we do also offer a LHD specific version here;

NOTE: The brake lever switch is a square plug, if your current one is different it will need to be modified to suit.

NOTE - If you have ABS you will need to block either the front most(closest to booster) or middle port (as they are the same port just split in two) with the provided tapered grub screw.
