Before & After
FAQs
What's the difference between the Pro and Pro Max?
Everything is the same except for the piston size:
- PRO Version(17.5mm): Best for Single Disc or relaxed Dual Disc riding. It offers a linear feel with a strong final bite but has slightly more lever travel (similar to stock).
- PRO MAX Version (19mm): Best for Dual Disc setups, aggressive riding, or track days. It provides instant bite with almost no lever travel (very stiff/direct feel). Recommended if you have a big motor build, chain conversion, or aftermarket calipers.
Are SuperGear master cylinders compatible with Touring OEM handlebars?
Yes. SuperGear master cylinders are designed to fit Harley Touring OEM handlebars without major modification when the correct application is selected. They can also be used with many aftermarket handlebars, but handlebar diameter, control clearance, mirror position, brake line routing, and switch housing fitment should be checked before installation.
Do SuperGear master cylinders require wiring modification?
No major wiring modification is required. The SuperGear RF7 master cylinder includes its own brake switch and is designed to connect with the bike’s factory wiring harness.
It is designed as a straightforward bolt-on installation, but professional installation is still recommended to properly bleed the brake system, check switch function, and verify safe operation before riding.
What brake fluid should I use?
Use DOT 4 or DOT 5.1 brake fluid only, unless your specific brake system requires otherwise. Do not use DOT 5 silicone brake fluid. If your bike previously used DOT 5, the brake lines and system must be completely flushed before installing the new master cylinder.
Does it come with a brake light switch?
Yes, it includes a pre-installed [mechanical / hydraulic] switch. It’s plug-and-play with your existing harness.
Why go Radial? (What's the benefit?)
Unlike stock axial pumps where energy is lost in the pivot, a Radial setup aligns the piston movement with your finger's pull. This minimizes flex and provides adirect, linear feel ,giving you precise feedback and way more stopping power with less effort.
